If you've been shopping for a new bike or upgrading your current one, you’ve likely come across the term “Boost” – especially when it comes to forks. But what exactly is Boost, and why does it matter? Let’s break it down.

What is Boost?

Boost is a modern standard for mountain bike hubs, axles, and forks that was introduced to improve bike performance and durability. Specifically, Boost refers to a wider hub spacing compared to traditional standards. For forks, this means a **110mm x 15mm thru-axle** spacing (up from the older 100mm x 15mm standard). This extra width provides several key benefits for riders.

Boost is a modern standard for mountain bike hubs, axles, and forks that was introduced to improve bike performance and durability. Specifically, Boost refers to a wider hub spacing compared to traditional standards. For forks, this means a **110mm x 15mm thru-axle** spacing (up from the older 100mm x 15mm standard). This extra width provides several key benefits for riders.

Why Boost Matters

1. Increased Stiffness and Strength: The wider hub spacing creates a stiffer wheel and fork interface, improving handling and control, especially on rough terrain.

2. Better Tire Clearance: Boost allows for wider tires and better clearance, giving you more options for tackling different trails.

3. Improved Chainline: The wider spacing optimizes the chainline, which enhances shifting performance and reduces wear on drivetrain components.

Is Boost Right for You?

Boost has become the industry standard for most modern mountain bikes, from cross-country to downhill. If you’re upgrading your fork or building a new bike, Boost is likely the way to go. However, if you’re working with an older bike or components, compatibility might be a concern. Always check your frame and hub specifications before making the switch.

Boost vs. Non-Boost

While Boost offers clear advantages, non-Boost systems are still functional and widely used. The choice ultimately depends on your riding style, bike setup, and future upgrade plans.



Boost on a fork isn't just a buzzword – it’s a game-changer for modern mountain biking. With improved stiffness, better tire clearance, and enhanced performance, it’s no wonder Boost has become the go-to standard for riders worldwide.

Whether you're a seasoned pro or a weekend warrior, understanding Boost can help you make smarter decisions about your bike setup. Ready to boost your ride?
