Compatible with first generation 9:ZERO:7 197/190 rear hubs ONLY. Works with Shimano 10/11spd, SRAM NX 11spd and SRAM 10spd. Comes with caps for either 197x12mm thruaxle or 190x9mm QR - please specify when ordering.
The design and quality of the freehub body seems great but the aluminum material with which the hub driver is made of seems to be to soft as my casette really chews it up after only a year of use. I have never had this issue on any of my other bikes Lyndsy on 13th Feb 2017
