This freehub Bitex MTF freehub body 6 pawl R07-M2C2 is for Bitex MTF hubs only. This will not fit the RAR road hubs. Well it will but it wont function properly.
This will fit the Bitex MTF hub which is there MTB hub. The freehub will take shimano and Sram 11 speed MTB cassettes and Shimano MTB road 11 speed 11-34T cassettes. Shimano/SRAM MTB/road 8/9/10 speed cassette also fit.
