Why Choose the Wolf Tooth Aluminum Single Speed Cog?

The Wolf Tooth Aluminum Single Speed Cog 20T in Orange has extra tall teeth for reliable chain retention when you run a chain tensioner. It is reversible, and Wolf Tooth says its 4.5mm wide base won't dig into your freehub body. It is made from 7075-T6 aluminum, and Wolf Tooth lists the 20T at 23.5g.

The cog fits a Shimano Hyperglide style freehub spline, geared or single speed. It does not fit Shimano Microspline or SRAM XD freehubs. It works with any 9, 10, or 11 speed chain and with SRAM Eagle, Shimano HG+, KMC, Wipperman, and Connex 12 speed chains. Wolf Tooth says it does not work with single speed specific chains, SRAM Transmission (T-Type) or road Flattop 12 speed chains, or Campagnolo Ekar 13 speed chain.

To set your chainline, Wolf Tooth makes a Single Speed Spacer Kit with a stainless steel lockring, and its Drop-Stop chainrings pair with these cogs. If you want more durability, Wolf Tooth also makes a stainless steel single speed cog.
