The XD 1-ER has been developed from our vision that riders with XD freehubs may want to go single speed without buying a new freehub. We entered the single speed market early and we know that riders still look for simple and elegant solutions to keep their bikes working in all conditions.

Utilising the splines and threaded XD freehub body our XD 1-ER kit is simple to fit and provides a 49 or 51mm chain line depending on the orientation of the suppled 3mm spacer. Going singlespeed on a modern SRAM equipped bike has never been so easy.

This kit is supplied with:

16t 5/64cog.

Steel Splined Flat Sided Spacer

Threaded Cog

3mm Cog

6x T25 Torx

SRAM XD compatible only.

17/18/19/20/22T cogs available separately.
