15 Tooth Cog

Features:

  • Machined from 4130 steel
  • black oxide coated post machining
  • Fits 1/8" chains (3mm tooth width)
  • Cog has chain shelf to allow ISO bolt heads to clear chain

Why only 15T?

Well.. you've got to start somewhere. 15T is my preferred gear on the street, and is currently unavailable from other ISO cog manufacturers. 15T also gives a good range of skid patches for varying gear ratios. More sizes on the way.
