DMR - Single Speed Conversion Kit
The single speed conversion kit is the most effective and easiest way of converting your bike to single speed set up without buying a whole new wheel. Two precision-machined anodised spacers sandwich a single 16t cog to replace your entire 8 or 9 speed cassette. Matched with a DMR Tension Seeker, it is possible to run a conventional vertical dropout frame as a single speed bike.
