Wolf Tooth Single Speed Aluminum Cog - 20t | Orange

Why Is the Wolf Tooth Single Speed Aluminum Cog Worth the Price?

The Wolf Tooth Single Speed Aluminum Cog 20t Orange is machined in Minneapolis specifically for reliability in single-speed and fixed-gear drivetrains. The teeth are designed with extra height compared to standard cogs, which provides better chain retention when paired with chain tensioners, a common problem point on single-speed setups running through bumpy terrain. The cog is reversible so you can flip it to extend service life by wearing both sides evenly, effectively doubling the lifespan of the part before replacement is needed.

At 4.5mm width at the base, the cog is engineered to avoid digging into your freehub body under load, a real concern with narrower aftermarket cogs on aluminum freehubs. Machined from 7075-T6 aluminum in orange anodized finish, it sits in the same color ecosystem as Wolf Tooth's headset spacers, seatpost clamps, and bar end plugs. Compatible with standard single-speed freehubs and freewheel hubs. A purpose-built part for riders who take their single-speed drivetrain as seriously as the rest of the build.
