Endless Bikes Kick Ass Cog - 19T - Black

- Machined 7075-T6 aluminum Singlespeed cogs
- Wide base prevents the cog from digging into freehub bodies and reduces flex
- Splines are machined for perfect alignment and fit on all mountain cassette hubs
- The shape, width and height of the teeth are CAD designed and optimized for Singlespeed use with 3/32" chains (1/8" OK)
- The design offers more contact with the chain rollers for better wear resistance of both the cog and the chain
- Positive engagement prevents chain slippage and makes for a very quiet drivetrain
- 100% made in the USA
