Qu-Ax Q-Axle Disc Hub, 36 Hole – Red

The ISIS axle has here been replaced by a technique that has been used in the cycle industry since 2002:

The axle has a 24mm diameter instead of the ISIS-typical 22mm and is more hollow which makes it lighter (the bigger diameter allows a thinner wall).

The cranks are no longer tightened as much on the axle as possible – but precisely positioned by an alloy cap and then fixed by tightening 2 Allen-key-screws on the crank.

The crank-connection has less wear and is more resistant to frequent assembly/disassembly.

Also, just like from taper square to ISIS, the connection-surface that transfers the pedalling-power is bigger.

Thanks to the more hollow-drilled axle, already the hub is more than 130g lighter than its ISIS-predecessor.

It also makes the axle stiffer.

As the bearings still keep the same outer-diameter, the hubs are compatible with all ISIS-ready-frames.
