Installing the Ultra Light SF-QR 2.0 Quick Release on your bike may seem daunting, but with a few straightforward steps, you can ensure a secure and efficient setup. This quick release skewer, available at Trifox, offers lightweight performance and reliability ideal for serious cyclists. Here's a detailed guide to help you install it correctly.

Step 1: Gather Your Tools

Before starting, gather the necessary tools:

Bike stand (optional but helpful)、Allen wrench or quick-release lever、Grease or lubricant

Step 2: Prepare Your Bike

Place your bike on a stable surface or bike stand. Make sure the bike is stable and won't tip over during the installation process.

Step 3: Remove the Old Skewers

If your bike already has skewers installed, you'll need to remove them first. Open the quick-release lever and unscrew the nut on the opposite side. Slide the skewer out of the hub and set it aside.

Step 4: Apply Lubricant

Apply a small amount of grease or lubricant to the threads of the quick-release skewer. This helps ensure smooth operation and prevents seizing.

Step 5: Insert the Ultra Light SF-QR 2.0 Skewer

Insert the new Ultra Light SF-QR 2.0 skewer through the hub axle. Ensure the lever side is positioned on the non-drive side of the bike (the side opposite the chain).

Step 6: Attach the Nut

Thread the nut onto the skewer from the drive side. Tighten the nut by hand until snug, but do not fully tighten yet.

Step 7: Adjust the Lever Position

Position the lever in an open position. The lever should be parallel to the fork or frame for proper alignment. Ensure the lever won’t interfere with any components when closed.

Step 8: Close the Quick Release

Close the quick-release lever. It should require firm pressure to close securely. If too loose, open the lever and tighten the nut slightly before closing again. A properly adjusted lever should leave an imprint on your palm when closed.

Step 9: Check Alignment

Ensure the wheel is properly aligned in the dropouts and centered between the forks or stays. Spin the wheel to check for any wobbling or misalignment.

Step 10: Test and Secure

Ensure the quick release is securely fastened by pressing down on the lever. There should be no movement in the wheel. For added safety, double-check that the lever is tightly closed and locked.



By following these steps, you can easily install your Ultra Light SF-QR 2.0 Quick Release, ensuring a secure and smooth ride. Proper installation not only enhances performance but also ensures your safety on the road.
