Originally designed for the Sram 11 speed 1x mountain bike derailleurs, these pulleys have a narrow-wide tooth profile for better chain retention. Cross seals only.
The 12 tooth pulley wheels are built to last: aluminum cogs, serviceable bearings: bring it on, cross season! Tested by Helen Wyman and ridden to a double Canadian National Championship by the Focus CX Team.
