Q-Axle Splined Cranks
These Qu-Ax cranks are specifically designed for their Q-Axle hub.
The Quax Q-Axle Splined Unicycle Cranks only fit their Q-Axle Hub. These use a splined system with pinch bolts to lock them to the shaft after being precisely position using an alloy cap. This crank interface is less prone to wear and is more resistant to frequent assembly/dissassembly. As with the ISIS interface, the Q-Axle interface is considerably bigger than with the tapersquare one, this means that the connection-surface that transfers the pedaling-power is bigger, stronger and more durable.
Material: Forged aluminium
Pedal Size: 9/16"
These cranks will not fit on ISIS hubs or KH/Onza Splined buhs, they will only fit on the Qu-Ax Q-Axle hub.
