What is Boost Spacing?

Boost spacing refers to a design standard for bicycle forks and frames that increases the outer width of the front hub and fork legs. It was introduced by the mountain bike component manufacturer, SRAM, in 2015.

The traditional front hub spacing for mountain bikes is 100mm for quick release (QR) hubs and 110mm for thru-axle hubs. However, with Boost spacing, the front hub width is increased to 110mm for QR hubs and 148mm for thru-axle hubs.

This wider spacing offers several benefits for mountain bikers. First, it allows for a wider spoke bracing angle, which leads to a stiffer and stronger wheel. This improves the overall stability and control of the bike, especially when navigating technical terrain.

Second, the wider hub spacing creates more clearance between the fork legs and the tire. This allows for the use of wider tires, which can provide better traction and a smoother ride over rough surfaces.
