Note: The 50T is a pretty huge cog and your derailleur may experience a fair bit of stress when shifting into and out of this gear. For best results, we highly recommend that you mod your derailleur cage to allow it to shift into the largest cog properly. See the link to our recommended option below.

Fits onto standard splined freehub bodies (not SRAM XD)
