*ONYX* vesper mtb boost iso ms hub rear (black aura)

"ONYX RACING RACING PRODUCTS" is the brand specifically making hubs from Minnesota, US.

This is their unique rear hub "Vesper" features one-way-scratch mechanism "Sprag Clutch".

12mm x 148mm boost hub, compatible with Shimano Micro Spline 12 speed .

The sprag immediately transmits torque to the wheel when you pedal without time-lag.

When the free wheel is spinning, the flat sprag reduces friction-loss and it benefits less speeding down.

Another feature of the hub is its ”quietness", while other brand's hubs make noise.

The ONYX hubs are popular not only for BMX racing but also MTB free rides.




The very specific and distinctive shape is reminiscent of old USA cult makers.
