ENDURO BEARINGS Derailleur pulleys - zero ceramic - sram - 11 speed - red

Upgrade your bike's shifting performance with these high-precision, machined Delrin derailleur pulleys designed for 11-speed SRAM derailleurs. Featuring Zero ceramic-hybrid radial bearings with black-oxide treatment, these pulleys offer enhanced durability, smoother operation, and improved longevity. The 500 AF Delrin material provides high tensile strength, natural lubricity, and resistance to moisture, chemicals, and UV rays, ensuring a highly durable and smooth-running pulley. The upper pulley uses CN (tight clearance) bearings for maximum shifting accuracy, while the lower uses C4 (loose clearance) bearings to accommodate chain-line movement. The 11-tooth profile with 4mm upper bolt-hole and 5mm lower bolt-hole makes these pulleys an ideal upgrade for most 11-speed SRAM systems. Available in various configurations, including the top-tier XD-15 Ceramic-Hybrid, all are proudly manufactured in the USA to meet high-performance cycling standards.
