*ONYX RACING PRODUCTS* vesper road hub rear (silver)
This is their unique rear hub "Vesper ROAD" features one-way-scratch mechanism "Sprag Clutch".
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.
This is the no-disc/135mm rear-hub, fits QR frames such as RIVENDELL or SURLY.
The very specific and distinctive shape is reminiscent of old USA cult makers.
