EXTRALITE Freehub Body Hyper + Special 72T-OP Open Program | SRAM-XD Ceramic
Special replacement freewheel from the Extralite Open Test program for HyperRear2, Hyper JR, HyperCamber2 or HyperBoost R rear wheel hubs.
The freewheel is based on a spur toothing, but not with 36 (like series) but with 72 teeth. This not only results in a noticeably shorter free travel until the frictional connection occurs, but also an incomparable sound. The direct power transmission offers clear advantages, especially in tough competitions or in technically difficult terrain.
The freewheel body was designed for maximum loads and also works with more than half a ton of force on the chain.
