The Problem we delete: Mountain bikers know the struggle: you want a new wheelset or have a spare wheel, but the axle doesn’t fit your fork. The difference between 20mm Boost and 15mm-Boost standards creates headaches for bikers worldwide. This often means expensive modifications or simply not being able to use your favorite wheel. Frustrating, right?

With this adapter Set you can put your 15mm x 110mm Boost Wheels in a 20mm  Fox 40 Downhill Forks. Ride all kind of 15 x 110 MM hubs in a 20x110 MM Forks from Fox. Only suitable for the Fox 40 Forks and equal models with the same dropouts. 15x110mm Axle is included. CNC machines produced adapters from extremely strong and lightweight aircraft-grade 7075 aluminum, adhering to the highest German manufacturing standards. Whatch this Video and see how easy it works.
