With bigger cassettes come bigger pulleys.
Designed for the Sram Eagle and Shimano 12 speed mountain bike derailleurs, these pulleys maximize the tooth count to reduce friction. Cross seals only.
The specific 14 tooth upper and lower pulley wheels are built to last: aluminum cogs, serviceable bearings to resist the most challenging mountain bike conditions.
