Singlespeed cogs and freewheels

Wolf Tooth Components Singlespeed Aluminum Cog

Size

If you're going singlespeed look no further than these top-quality cogs from Wolf Tooth Components. These fit on any Shimano-type free hub body (most common freehub body type on cyclocross, gravel, and adventure bikes). They work with any chain but are optimized for 9/10/11 speed chains. 

Each cog is beautifully crafted from 7075-T6 aluminum in Minneapolis, MN, USA. They are reversible, so you can extend their life by turning the cog around to run the other way, evening out the wear. They feature extra-tall teeth for reliable chain retention. 

A common problem when using singlespeed cogs on wheels designed for a 8/9/10/11 speed cassette is that the base of the cog can dig into the freehub body. Narrow steel cogs can gouge the freehub body, especially if the freehub body is aluminum. Wolf Tooth's design uses an extra-wide 4.5mm base to prevent this from happening. 

TECH SPECS:

  • Weight - 22T= 23g, 20T= 20g, 19T= 18g, 18T= 16g, 17T= 15g, 16T= 11g
  • Fits any Shimano-compatible freehub body (you'll use spacers on either side to adjust chainline and occupy the space the cassette would normally take up)

FIT GUIDELINES: 

  • 7075-T6 offers a great combination of light weight, strength, and durability, so they are great for bikes where weight counts, like cyclocross race bikes. If you prefer a more durable cog, at the expense of weight, consider a steel cog as an alternative.
  • Pair your cog with Wolf Tooth's Drop-Stop chainrings for your crank, and you have the ultimate singlespeed cyclocross drivetrain.
