Enduro Directline pulley sets are designed and manufactured for performance.
These pulleys feature CN (tight clearance) XD15 bearings in the upper pulley to maximize shifting accuracy and C4 (loose clearance) XD15 bearings in the lower pulley to allow for chain-line movement.
Precision machined from Teflon® infused 500 AF Delrin® material, these pulleys greatly reduce friction between the pulley and the chain while offering significantly less drag than pulleys machined from aluminum or titanium. Directline pulleys spin on corrosion-proof XD15 Ceramic-Hybrid bearings to provide the ultimate high performance bearings and include a lifetime warranty. Available for a wide variety of Shimano and SRAM road and mountain bike derailleurs.
