At present, the braking system of road bikes is divided into two categories, disc brakes and rim brakes (rim brakes are also called v brakes). Earlier, road bikes generally used rim brakes, while disc brakes were mostly used on mountain bikes. With the gradual emergence of disc brakes in the Tour de France, more and more users using disc brakes on the market have also followed. The braking of the rim brake mainly depends on the friction braking between the brake block and the brake edge, while the disc brake uses friction braking between the pad and the disc. Compared with the disc brake, the weight of the rim brake road bike will be lighter. Due to structural problems, disc brakes are heavier than rim brakes. Although disc brakes are heavier, they sacrifice weight for better braking power and heat dissipation. For carbon fiber wheelsets, disc brakes are more friendly to the wheelset, and there will be no frame-burning phenomenon of rim brakes when going downhill for a long distance, which greatly improves the service life of the wheelset (the phenomenon of burning frames is mainly due to long-term driving Slope, the brake block and the brake edge have been rubbed for a long time, and the heat dissipation is not timely and the frame is burnt) On rainy days, the braking force of the rim brake will drop to a certain extent, and the advantage of the disc brake will be more obvious when going downhill for a long distance, so there is no need to worry about the phenomenon of burning the frame. Disc brakes are better than rim brakes in terms of the braking cube and stopping distance. Secondly, in terms of price, the price of rim brakes at the same level will be cheaper than disc brakes. The working principle of the rim brake caliper is mainly that the brake handle is connected to the brake line, and the brake line pulls the caliper so that the brake block on the caliper and the brake edge on the wheelset friction brake. Disc brakes can be divided into two types, mechanical disc brakes, and oil brakes.The working principle of the wire pull disc brake is similar to that of the rim brake caliper, but the oil brake is different. When the brake handle is pressed, the oil in the oil pipe is pushed to push the piston, so that the pad and the disc rub. Note: Because rim brakes and mechanical disc brakes are pulled by wires to brake, the material of the wire tube and the way of wiring will have a certain impact on the feel of the brakes, so the oil disc does not need to consider such a problem. Disc brakes and rim brakes for road bikes have their own advantages and disadvantages. The real choice depends on personal preferences and needs. The first is the braking force. For most situations, the braking force of the rim brake is absolutely sufficient, otherwise, it is impossible to be active in the Grand Tour for so many years. However, there is a shortcoming of the rim brake, that is, the braking force is insufficient when the carbon blade is used and the brake pads are not very good, and the braking force will also be attenuated on rainy days. The risk of burning the frame, but with the maturity of carbon knife technology, this situation is rare. In contrast, disc brakes will have more stopping power than rim brakes on rainy days and are equipped with carbon blades. This is a major advantage of disc brakes. Besides the weight, if you are pursuing ultra-lightweight, it is recommended to use rim brakes. After all, although the current disc brake technology is relatively mature, the weight is still a big problem. It may be easy to assemble a tank. Rim brakes will weigh a lot less in comparison, which is one benefit of rim brakes. Disc brakes have a big advantage in cable routing. Due to the special structure, the rim brake frame generally cannot completely hide the wiring. No matter how you hide it, there will always be a part of the line leaking out (of course, the inability to run all the way will also cause most rim brakes to feel good). Those who pursue beauty and simplicity, they can give up. Then you can refer to this Full internal carbon Routing road bike frame： Trifox X12 frame. Finally, let’s talk about maintenance. The braking logic of the rim brake is relatively simple, especially since the brake pads are easier to replace and relatively easier to maintain, and there will be no messy problems such as rubbing against the rim and making abnormal noises. The maintenance of disc brakes is more troublesome. The oil disc needs to be refilled and exhausted when disassembling and assembling. Moreover, since the brake pads of pads are approximately equal to the brake pads of the rim brakes, the clearance is small, and very fine adjustments are required when installing them for the first time. otherwise, it is easy to rub the disc, and generally, it takes a lot of time to adjust the disc brake. Rim brakes are more advantageous in terms of maintenance.
1.Choose a hardtail frame First, let me briefly talk about the importance of frame size. The frame size must fit your body. If it is too large or too small, it will affect your riding posture, causing you to ride harder than others, and may cause sports injuries for a long time. However, this is not absolute. For example, if you often go up and downhill, then the frame size should be smaller. If you only use it for flat road riding, then it does not matter if the frame size is slightly larger. The frame material is of course titanium alloy or carbon fiber is the best. 2.The front fork is a high-tech component of mountain bikes. Mountain bikes with hard front forks are rare, and they are basically front forks with shock absorbers. Spring Forks: The lowest range forks with no damping. Features: cheap, the most common. Resistance fork: The resistance fork is used as the medium without damping. Features: More than the above, but more than the bottom, but the resistance fork will age after about three years and needs to be replaced. Oil spring fork: the spring is used as the rebound medium, and the oil is used as the damping. Features: The heaviest, but the strongest. The spring is relatively smooth to use and responds sensitively to small vibrations. Generally, the shock absorber oil is changed every six months, and the fork is removed to change the oil. Oil-air fork: Air is used as the rebound medium, and shock oil is used as the damper. Features: Lighter than the oil spring fork, but the firmness is reduced. If you pump up the gas every six months, the car dealer will provide a special pump for free, and you can buy it separately. The advantage of using air as the medium is that it is lighter in weight and can protect the rider’s wrist during high-speed off-road, but it is not very sensitive to small vibrations. 3.The braking system includes brakes, brake levers, and brake lines. There are two kinds of brakes for mountain bikes: V brakes and disc brakes, while suspension brakes for ordinary bicycles are not common. V brake: The force is very strong, because it is braked by the friction rim, so the rim must be adjusted in place, and it is not easy to deform. Disc brakes: Compared with V brakes, it is less likely to lock the tires. When driving at high speed, locking is very dangerous and will cause sideslips and rollovers. There are two types of disc brakes: hydraulic disc brakes and mechanical disc brakes. Hydraulic disc brakes rely on oil to press the brake pads to obtain huge braking force. Wire-pull disc brakes rely on the power of your fingers to brake. Now, V brakes have been phased out one after another. Disc brakes are better in terms of aesthetics and practicality. The only trouble is that sometimes you need to adjust the brakes to make the gap between the pads. V brakes are more dangerous than disc brakes when riding downhill on rainy days, and are more prone to brake failure. For long-distance riding, one or two pairs of pads must be prepared, especially in mountainous areas. As for the oil pressure and machinery, it depends on your own choice, and the machinery is better maintained. If the oil brake is broken on the road, most cities cannot repair it, especially in remote areas, you can only either express a new one or replace it with a mechanical one. 4.The transmission system includes a crankshaft, a central shaft, a chain, and a flywheel. Tooth plate: also called tooth plate. Most of them have 3 gears, and some people change them to two gears in pursuit of lightweight. Central axis: There are three types of integrated central axis, plum blossom hole central axis, and square hole central axis. Chain: This is a consumable item, and the chain is often broken. A good chain drive is flexible and will not wear out after long-term use. Flywheel: There are 7-speed 21-speed, 8-speed 24-speed, 9-speed 27-speed, 10-speed 30-speed, and 11-speed 33-speed. 5.The speed change system includes a shift handle, a front derailleur, a rear derailleur, and a speed change cable. 6.Wheels include rims, steel wires, front and rear axles, outer tires, and inner tubes. Rims: Double-layer rims should be used for mountain bikes. Because the double-layer ring is stronger than the single-layer ring, it can better withstand the test of the performance of the bicycle on harsh terrain. Steel wires (spokes): There are two types, one is common, with a circular cross-section; the other is flat (wind resistance strips), which can reduce frontal wind resistance. Axle: also known as flower drum. Friends who use disc brakes should choose disc brake shafts because the disc brake pads are fixed on the disc brake shafts; friends who use V brakes can use ordinary shafts. If you want to upgrade to disc brakes in the future, you can install disc brake shafts first. Tire: very important, because it directly affects the rider’s handling of the car on a specific road. Different tread patterns adapt to different road surfaces. The flatter the tread, the less resistance, the faster the speed, and the stronger the friction on flat ground. Skinny tires are suitable for flat concrete roads in the city. The more convex the tread, the greater the resistance, the slower the speed, and the stronger the friction on the mountain. if you want to check more bike knowledge, you can pay attention to our official web.
Even though aerodynamics is widely accepted these days, most of us cyclists still wish our bikes were lighter. Probably from the earliest days of bicycles, cyclists have been trying to make their bikes lighter. We’re sure Octave Lapize, the first rider to climb Mount Duttmare in the 1910 Tour de France, would have liked his bike to be lighter. No matter what era, if you’re riding a bike, you have to push the weight of the equipment with your own effort. As a result, cyclists tend to think about taking weight off their equipment and being happy to lose even a little weight. In recent years, with the improvement of academic understanding and research knowledge of aerodynamics, and being accepted by the majority of cyclists, aerodynamics is regarded as the kingly way to ride faster. Studies have shown that, except on the steepest climbs, aero bikes are generally faster than lightweight-oriented bikes. It’s crucial for racers, but for most of us cycling enthusiasts, saving weight is still a welcome act. Below we’ve outlined some weight-saving upgrades and tips to help keep your bike’s weight down. Handlebar While the effect may sound insignificant, you can actually save up to 80 grams by swapping out your aluminum handlebars for carbon fiber ones. You can go a step further and see them short. I recommend the Trifox bike Carbon Riser Handlebar RHB300, which weighs in at 187g and is very reasonably priced. Tires and Tubes If your bike comes standard with heavier, cheaper tires, upgrading them can provide some solid weight savings and improve ride quality. This inexpensive upgrade also comes with the all-important problem of generally reduced puncture resistance. But for many lighter-weight cyclists, it’s a risk worth taking. Wheels To keep costs at a minimum, manufacturers often equip their entry-level to mid-level bikes with more durable components. Especially when it comes to wheelsets. Low-end and mid-end vehicles are usually equipped with aluminum alloy wheels, which are usually heavier than carbon fiber wheels. If your wheels are heavy, upgrading them could save a lot of weight. Depending on the wheelset you choose, it may even be possible to save up to half a kilo. spare parts Another simple weight-saving measure is the option to replace the saddle, seat posts, and pedals that come with the bike with lightweight alloy or carbon fiber versions. These modifications are also less expensive than replacing your wheels and drivetrain. If you’re going to ride for a long time, not just lightweight for climbing, Trifox bike has a lighter carbon bow saddle option. The trifox bike CS100 saddle, which weighs only 106 grams, has also attracted attention for its perfect combination of comfort and weight. Another great way to modify is to invest in a lightweight seat post. The SLS21 Bike Seatpost is my personal favorite, ditch unnecessary items like a second bottle cage; swap out all-stock steel bolts and nuts for titanium versions, and upgrade to lightweight quick releases or thru axles pole. When every moment counts, you can also consider sawing off the overly long front fork steerer tube and seat tube. Sawing off the excess can actually save a lot of weight. Tips for light-weighting without spending money If you’ve already saved a lot of weight with component upgrades, trimming the excess length of the cable and bar tape can save a few more grams. If your bike has external cable routing, optimizing the cable routing will also help improve aerodynamics at the front of the bike. The brake and transmission cables of the whole car are usually relatively long when they leave the factory. Cutting them as short as possible can save considerable weight. When operating, please note that if it is too short, it will affect the braking and shifting performance. Road handlebar tape and handlebar plugs also save weight. Inflatable handlebar plugs are much heavier than simple plastic ones, and I like to keep a pair of lightweight handlebar plugs on hand so I can attach them to a new bike no matter what bar strap I’m using. Thicker silicone bar tapes are usually heavier, thinner cork tapes are usually the lightest, and you can save on tape if you tie the bar tape as tight as possible. As controversial as it may seem, toss your valve caps and locknuts in the trash, save some weight, and if your valves are going to rattle against your rims, just secure them with some duct tape. You can also swap out the steel screws for bottle cage mounts, headset lid mounts, and other non-fasteners for lightweight alloy screws for even more weight savings.
Anyone who loves cycling will know that bicycles are mainly divided into four categories： The first category is civilian vehicles, which are the most common transportation vehicles; The second category is mountain bikes with thick tires; The third category is called climbing car; Another category is road bikes. The road car used in the competition, we usually call it “racing car”. Tire Road 700C is equivalent to 28 inches, and mountain bikes have a wheel diameter of 26 inches; mountain bike tires are usually above 1.9″ (1.5″ may be used for special tracks), while road bike tires are mostly around 20mm wide. Handlebar controls In order to ride on rugged mountain roads and pursue control, the mountain bike uses a wider handlebar, while the road pursues speed and reduces wind resistance, so the handlebar is narrower. Frame On bumpy roads in the mountains, the consideration is the combination of lightweight and hard work, while the focus of road considerations is pedaling rigidity and lightweight. Road bikes are usually slender (and aerodynamically designed frames are thicker in recent years), while mountain bikes are stronger. The frame angle of the mountain bike is very particular, and the angle of the road bike is similar. Mountain bikes have thicker axles, while road bikes have more delicate axles. At present, with the application of manufacturing technology and high-tech materials, it is difficult to find any similarities between the two frames except for the basic structure. Brake Mountain bikes require powerful, powerful braking, and all-weather braking systems. The earliest mountain bikes used a suspension brake system and the V-shaped brakes that appeared later provided better braking performance. The best braking system now is the disc brakes, introduced by motorcycles. In addition to braking power, the most important thing about road bikes is lightweight. Front fork The front fork of the mountain bike is an important part of the mountain bike. It has high technological content, a combination of performance and comfort, rigidity and lightweight, while the front fork of the road bike is just a part related to the frame. Weight Weight is very important for mountains and roads. During competitions, mountain bikes can reach 12.5kg, while the maximum limit for roads is 10.5kg. The heavier the car, the more energy you consume, virtually increasing your excess consumption. Precautions The appearance of the mountain is complicated, and there is no road. It feels simple and smooth. Of course, some of them cannot be seen by their appearance. What needs to be seen is the overall effect of the car, especially during the riding process. Mountain bikes feel relatively stable, and comfortable, and have very good maneuverability and braking; all road bikes are designed to emphasize speed because the narrow tire width has high requirements on the road surface, and wet and slippery roads are easy to slip and have poor flexibility.
Breaking the wind is the necessary process for cyclists to lead to victory!If you do not fully prepare, it will consume your stamina bit by bit and become the biggest enemy on the field.Even if they have excellent aerodynamic bicycles and ultra-low wind resistance cycling equipment, riders can only get a certain amount of help on the field. It does not mean that they can get the first opportunity in the leading group, and there is no guarantee that they can stand in the awards the stage accepts cheers because the output power is determined by physical fitness. If riders have good equipment and attitude, they can play an important role in the key to victory.For advanced riders who are looking for speed and fighting every second, you must know the 10 tips for creating low-drag riding. The following are the bike parts, personal parts, and body parts, respectively, and explain in order the ways in which road bikes can achieve low-resistance riding settings.Bike parts selection1. WheelsIn principle, a rim height of 35mm or more can produce a wind-breaking effect. Although the higher the rim, the better the wind-cutting effect, if it encounters a crosswind, it will become difficult to control. Considering the front wheel, it is recommended to use 50mm. For the high-frame wheels, the rear wheels have no handling problems and the overall center of gravity is also on the rear wheels, so wheels with higher rims can be used.The part that can exert the maximum aerodynamic performance is the wheelset. The picture above is an AERO wheelset of Trifox. There are 45mm, 50mm, and 60mm for your choice.2. HandlebarIn addition to the appearance of the body to minimize the wind resistance area and make the whole more streamlined, some bike handles use a hidden wiring design, which hides the wiring inside the handlebar. Not only does the car become more concise, but it can also more or less Reduce wind resistance.3. TiresTires that seem to have nothing to do with low wind resistance, in fact, the tread pattern and width will also affect the wind resistance coefficient. It is recommended to choose a smooth and flat tread pattern to minimize the wind resistance friction coefficient, and the width of the tire should be echoed with the wheelset to avoid Choosing wider tires to produce greater wind resistance.Although there is no so-called aerodynamic tire, choosing a bald tire and a suitable width can help.Personal parts selection1. Low wind resistance helmetIt is the most straightforward way to buy a road helmet with low wind resistance. Its appearance is similar to that of a timing helmet. As the rider may face downwards in the final sprint, there is no drop-shaped tail end design. Some brands of road bike helmets are sold separately with caps. By covering the vents to reduce wind resistance, some ventilation will be sacrificed. If your budget is limited, you can add a smooth cap to your existing helmets, which is economical and affordable.2. Shoe coversThere are usually Velcro or laces on the surface of general car shoes. In order to reduce wind resistance, it is more economical to wear shoe covers directly. On the other hand, many shoes on the market pay attention to low wind resistance design, through surface treatment or the whole piece of smooth design, making the whole pair of shoes more streamlined.Wearing shoe covers directly is a more economical way, and the laces and Velcro are not exposed.3. One-piece cycling suitCompared with the separate styles of the upper body cycling jersey and cycling pants, the one-piece cycling underwear is more streamlined, and the seam point is located on the lee side of the front of the jersey. In addition, the appropriate size and tailored tailoring design make the whole set the cycling clothes attached to the body, but the disadvantage of the one-piece cycling suit is that the ventilation effect is not ideal.Body part selection1. Cycling postureThe wind resistance area of the human body is much larger than that of a bicycle. If you want to reduce wind resistance, you can change the cycling posture to create a better low wind resistance effect. Riders who are very particular will perform fitting according to their needs, usually, by adjusting the saddle forward and lowering the handlebar height, The body seems to shrink into a ball, but this posture will not be very comfortable, and the body will easily feel tired.Many riders think that holding the lower handlebar can reduce the wind resistance more than holding the upper handlebar, but in fact, the cycling posture is not as low as possible, but the more level the better, so it is recommended to hold the upper handlebar with both hands. In the horizontal state, the helmet and the back are in a straight line, and the pedaling posture is maintained in a vertical state.2. Shave leg hairDifferent people have different opinions on the effect of shaving leg hair. Some riders have the habit of making the body surface smoother, but after all, leg hair is a part of human skin and has a warming effect. If you really want to shave leg hair, it is usually best. There is such a habit, try not to do it before the game, otherwise, it may cause skin allergies or infections.3. Reduce excess body weightIf you accidentally get too much luck or your BMI exceeds the standard range during the New Year holiday, it is recommended to find a normal way to reduce weight. An average weight loss of 0.5kg per week is more appropriate. It can reduce overall weight on the one hand, and reduce weight on the other. The windward area can also have little effect on reducing wind resistance.4. Reduce wind resistance through wheelsWhen riding, the body will divert the wind resistance to both sides. When the airflow converges again in the neutral position, a so-called low-pressure zone will be generated. There is no wind resistance in the area. If the team is moving through the division of labor and cooperation, it will not only It also achieves the effect of reducing wind resistance and also saves energy.
In today's life, many bicycles, especially mountain bikes, have an obvious groove on the saddle.As for why this design is used, many people don't know why, and many experienced cyclists have different unique opinions.In fact, leaving a hole in the saddle makes this design more humane. The earliest bicycle saddles were designed based on saddles, and this design is still in use today.1. Cost savingThe hollow design in the middle of the bicycle saddle is much more complicated than the integrated design in the production process.Some people think that it is cost saving. In fact, this is impossible. At most, it can only save some materials. However, the cost of craftsmanship and manpower far exceeds the cost of materials.2. Reduce weightSince the material of the saddle is reduced, the weight of the saddle will inevitably be reduced.For cyclists, especially for races, a little weight on the bike is very important. Although it looks small, it reduces the streamlined wind resistance of riding, which can better save people's physical strength and is suitable for long-term riding.3. Relieve stressPeople who often ride bicycles will definitely feel this way. After a long period of riding, the hip will feel the pain of tearing.In fact, it is caused by the force between the sides of a person's hips (sit bones) and the saddle during riding. There are many nerves and blood vessels in the human sciatic bone. The hollow design is mainly to solve the pressure on the blood vessels and nerves in this area, so as to relax our feeling of pressure and discomfort when cycling, and make cycling more healthy!4. VentilationAfter cycling for a long time, there will be a lot of heat in the position of the buttocks, which will produce a lot of sweat. This design plays a role in ventilation and heat dissipation to a large extent, so it is very necessary for the bicycle saddle to be breathable.5. Beautiful and generousWith the development of science and technology, according to people's pursuit of life, the novelty of models makes it easier to attract consumers and promote product sales.Just like many people buy a bike, in addition to performance and price, one thing that cannot be ignored is that its appearance is enough to attract them.Nowadays there are too many sub-healthy people. It is good to buy a bicycle and start cycling. It is environmentally friendly and can also exercise~ Don't be so lazy in life. Be sure don't eat too much and move your legs often!Click Here to buy Trifox Carbon Fiber Bike saddle, suitable for up and down lock or left and right lock seat posts, such as the seat post of trifox full carbon fiber road bike X16.
Among the three largest consumables of bicycles (chains, tires, brake pads), Relatively speaking, brake pads are relatively low in consumption and replacement frequency. Compared with chains, tires, and other accessories that are easy to lose money, hardly notice it. After all, the frequency of replacement is not high and the size is small. You can find the problem only if you watch closely. But in my opinion, the brake pads not only play an important role in safety protection but also a window that shows the low-key luxury taste and cycling values. Well, let's find out, there are some particularities in the choice of brake pads.Love and hate between brake pads and rimsWe know that when the brake pads directly contact and act on the rim, physical reactions such as braking, heat generation, and wear will occur. In addition to the primary function and consideration of braking force, we should also consider whether the material of the brake pad and the rim can be perfectly matched.In addition to the heat generation that bike friends are most concerned about, the "frame burning" is caused by friction and heat, and the temperature is too high; the second is wear. Under the action of friction between the brake shoes and the rim, both sides will cause a certain degree of wear. The material, the brake method, and the friction time will affect the degree of wear.The brake pads used in metal rims are rated at 180 degrees Celsius, while the brake pads used in carbon fiber rims are rated at 320 degrees Celsius. Therefore, the brake pad materials for carbon rings, aluminum rings, and ceramic rings are different. Brake pads are not just a piece of brake pads, and you need to change them when you use them up, but make a reasonable choice based on the material of the rim.MaterialThe material of bicycle brake pads is mainly composite rubber and cork. At present, the mainstream brake pads on the market use composite rubber. Due to the requirements of different material rims, the synthetic composition is different, which is better in terms of temperature and wear. Ground protection of the rim. Cork brake pads appear earlier and are extremely difficult to wear. They perform better in temperature control and in humid environments, but generally speaking, the braking force is relatively weak.RecommendBrandTrifoxModelWT18Typelight weight wheelsetStyleQuick ReleaseMaterial100% Carbon FiberSize700CDepth40mm/45mm/50mm/60mmRimFinish: UD / MattDrills: Front:20; Rear:24 HolesWidth: External 25mmBrake SystemV BrakeO.L.DFront 100mm, Rear 130mmFront Hub2 bearingsRear Hub4 bearingsHub materialAluminum AlloyCassette CompatibilityFit for 8/9/10/11 speedSpoke MaterialStainless SteelSpoke BrandPillarNipplePillar alloy nippleTire TypeClincherRider Weight Limit100kgRecommended tire size700C X 25CRecommended tire pressure 90-135psiPackage Content1 Pair Carbon Road Bike Quick Release Wheels (come with hub already)1 pair Cloth Rim Tape (Nylon Rim Tape Clincher, Wheel Strip Inner Tube Pad)Guarantee2 yearsClick here to buy Carbon Road Bike Quick Release Wheelset WT18
The bike rides through thousands of mountains and rivers. It is inevitable that the road will be rugged. The wheels collide with the bumpy road for a long time. The gradually swaying rim will not only affect the riding feeling but also cause an uneven braking feel. Today, teach you how to do it yourself DIY to correct it to avoid the fate of returning the rim to the original factory due to excessive deflection!Many tools on the market have the function of adjusting the copper head, which can be operated by choosing a coil adjuster (copper head adjuster)Learn about adjusting the rimThe correction of rim deflection is mainly by adjusting the spoke tension on the left and right sides of the rim to balance it to center the rim. ●The direction of adjusting the copper head of the spoke is opposite to that of the lock screw. Counterclockwise is to lock and clockwise to loosen. For example, if the rim yaw position is to the right (the right spoke has greater tension), it depends on whether the spoke at that place is a right spoke or a left spoke. If it is a right spoke, the tension is relaxed clockwise; If it is the left side, tighten it counterclockwise, and at the same time, adjust one spoke (the other spoke) in the opposite direction. ●The adjustment range of the copper head is limited to 1/8 to 1/4 turn each time. After the adjustment, turn the rim to check and fine-tune slowly. Do not adjust too much at one time, which may cause serious consequences.Rim deflection correction!This time the main purpose is to simply improve the cycling and braking feel. The brake pads of the bike are used to make judgments and corrections. For example, turning the bike upside down in the demonstration can be more convenient for operation.1. Adjust the brake stroke knob to make the brake block closer to the rim to facilitate the judgment of the deflection condition.2. Rotate the wheelset, and find out the deflection part by observing the change of the gap when the rim passes the brake block.3. Mark the most severely distorted spoke with a mark, use the adjuster to adjust the spoke, as well as one, spoke before and after it (according to the above-mentioned adjustment technique), then repeat steps 2 and 3, repeat the correction to satisfaction status.After the rim has been rectified, adjust the distance between the brake pads to an appropriate distance, and confirm that the brake is centered, so as to prevent the rim from being distorted due to long-term uneven force.This time, only simple adjustments are made for the left and right deflection of the rim, but the professional rim correction also includes details such as full circle and diagonal tension, or some wheels use special designs with non-square copper heads. If the cyclists need it, It is recommended to ask a professional technician or the original factory to assist in the correction will be more accurate!Click Here to buy carbon fiber road bike wheelset
The handlebar is too long? The wrong posture is destroying your shoulders.A longer handlebar means more stable handling, right? Usually, the short answer from riders is "YES".However, for a rider with a height of 1.9 meters, the 800mm long handlebar will give the rider a super comfortable and stable experience during the ride, while effectively maintaining the stability of the shoulder control and smooth turning. Sex. It seems that everything is perfect, but for the majority of ordinary riders, too long a handlebar brings comfort and also tends to hurt your shoulders invisibly.Too long handlebar will reduce the range of physical activityLooking back on the recent mountain cross-country trips, you felt your shoulder pain? If this happens frequently, it's time to re-evaluate the riding posture during off-roading. In the cross-country process, the most stable posture should be a slight external rotation of the humerus (upper arm bone), the elbows are slightly lowered, and the shoulder blades sink backward. It is a bit like the meaning of "sinking shoulders and falling elbows" in traditional Chinese martial arts. Such actions can stabilize the scapula and shoulder joint muscle tissue, and effectively improve and cope with the range of physical activity in the cross-country drop. The opposite movement (elbow, shoulder shrug), usually because the handlebar is too long, the force will not be smooth, the movement will become stiff, which greatly increases the risk of shoulder joint injury.Aaron Gwin's perfect postureLet's take a look at how downhill champion Aaron Gwin maintains the correct cross-country posture on the field-notice that his shoulders are not high, the upper arms are slightly externally rotated, and the positioning of his elbows: elbows and handlebars It's close to the level, and it's not raised high, close to the shoulder. The whole action is very standard! Aaron Gwin has incredible strength, strong back rotator cuff, and scapular muscles, which can help him to accept the rapid impact of a continuous drop and maintain stability.Wrong posture comparisonJust like running, it is difficult to perceive what your movements are like during the riding process, so it is best to take a good friend to rush the mountain, which can help you record the cycling posture. When reviewing the cycling video, you can check whether your elbow and shoulder movements are wrong. Is the elbow raised exaggeratedly and the shoulders raised? If this is the case, you may need to replace it with a shorter handlebar.The key is to find a balance between the position that can effectively control the shoulders and elbows and how comfortable you feel. Remember, the perfect balance point may not be an 800mm long handlebarClick here to buy Carbon Fiber Handlebars
