The Wolf Tooth "Single Speed" MTB Cog - Aluminium is a single speed cog machined from 7075-T6 aluminium for Shimano HG freehub bodies, on a geared or a single speed hub. The extra tall teeth keep the chain on even with a chain tensioner, the 4.5 mm wide base does not dig into the freehub, and the cog is reversible. It runs with 9, 10 and 11 speed chains and the 12 speed chains from SRAM Eagle, Shimano HG+, KMC, Wipperman and Connex; not with single speed specific chains, SRAM T-Type, Flattop or Campagnolo Ekar. Not for Microspline and XD. Weight 19 g (18T), 21 g (19T), 23.5 g (20T). Set the chainline with the Wolf Tooth Single Speed Spacer Kit; the Drop-Stop chainrings are the matching front end.
