Description

The Excess steel cog is a straightforward rear cog with a Shimano fitment, so it goes onto any cassette hub built to that standard. It comes in seven sizes, from 12 tooth through to 18 tooth, which makes it an easy way to try different gearing on a race setup.

It is machined from steel and finished in black, with no other colour offered. The 16 tooth version is listed at 30 grams.

Features
  • Fits Shimano cassette hubs. Built to a Shimano fitment, so it drops onto any cassette hub that takes that standard.
  • Seven sizes, 12T to 18T. Choose 12, 13, 14, 15, 16, 17 or 18 teeth to change your gearing without changing anything else.
  • Made from steel. A plain steel cog for riders working out which gearing suits their setup.
  • 30 grams in the 16T. The 16 tooth version is listed at 30 grams, so a gearing change adds very little weight.
  • Black across the range. Every size comes in black, the only colour offered.
