Wolf Tooth Stainless Steel Single Speed Cog

Wolf Tooth Stainless Steel Single Speed Cog is engineered for riders who demand durability, clean engagement, and refined machining in a singlespeed drivetrain. Precision-cut from 416 stainless steel billet, heat-treated, and electropolished for corrosion resistance, this cog delivers long wear life with a premium finish that stands up to year-round riding.

Designed with extra tall teeth, this singlespeed cog enhances chain retention—especially when paired with chain tensioners. The tooth profile ensures secure engagement under load, helping maintain consistent power transfer on trail, gravel, or urban builds. The cog is also reversible, effectively extending its service life.

A 4.5mm base width distributes load across the freehub splines to prevent gouging or damage, an important detail for riders running aluminum freehub bodies. Lightweight yet highly durable, this stainless steel cog strikes the right balance between longevity and rotational efficiency.
