These are the lightest weight and best looking stainless steel single speed cogs available. They feature extra tall teeth for reliable chain retention when using chain tensioners and are machined from 416 stainless steel billet with heat treating and electropolishing post processing for durability and corrosion resistance. They are reversible and feature a 4.5 mm width at the base that won't dig into your freehub body. 

Compatibility

• These will fit on Shimano Hyperglide style freehub spline (geared or singlespeed).
• Not compatible with Shimano Microspline or SRAM XD freehubs.
• Designed to work with any 9, 10, and 11 spd chain and SRAM Eagle, Shimano HG+, KMC, Wipperman, and Connex 12 spd chain.
• Not compatible with single speed specific, 12 spd SRAM Transmission (T-type) and Road Flattop chain or Campagnolo Ekar 13-spd chain.
