The GOKISO hub for Disk Brake also comes with our original rotation performance. It suits for MTB, CX, and Disk Brake Road Bike. The shock absorbing elastic suspension performs its ability at rough road and keep the bearings’ rotation smooth.
Removal and maintenance of free body with the GOKISO special tool, and Campagnolo compatible freehub body and Shimano compatible freehub body are replaceable. (Shimano 11s ⇔ Campagnolo 10/11s)
Special tool designed for the GOKISO Hub is able to easily replace and maintain the freehub body of the GOKISO Hub which are precisely assembled without damage.

Cobblestones bike racings are popular bicycle tours in Europe. When racing on such a rough street, a hub must bear a deadly impact (approx. 600kg weight) in every moment. With a standard hub structure, a shaft easily gets deformed and axle becomes deflected causing bearings to twist.This creates a constant"put on brake"condition on the bearing, caused by abraded steel bearing balls . As a result, more pedaling force is required. GOKISO Hub adopts a spring-structured and elastic body suspension around the bearings with a 0.5mm play to absorb the shock. This system minimizes the shock without sacrificing its rotation performance.
A slim and lean shaft sounds ideal for light-weighted bicycle hubs, but it lowers the strength and makes a shaft more vulnerable to deflection. A hub shaft could get deformed during wheel installation.Our spherical nut and washer are the successful solution for these problems. By keeping the hub shaft straight regardless of frame deformation, we have achieved the highest rotation accuracy without abrading or damaging the bearing.
Ball bearings in a bike hub must be big enough to support its load, thus, larger its diameter, the bearing balls suffer more friction and heat generation. As a result, it degrades the rotation performance. The GOKISO Hub use of 2mm-diameter"micro steel balls"made of the highest quality material used for precision machines is certainly unique. The roundness accuracy of the "Micro steel balls"is well illustrated by this is if the ball was the size of the moon, the surface roughness of the ball would be as little as 70m.
