SRAM X0 Type 2, 2.1 Rear Derailleur Pulley Kit

SRAM developed this replacement pulley kit to maintain the precise shifting performance of X0 Type 2 and 2.1 rear derailleurs. The set includes both the upper and lower pulleys along with the necessary bearing plates for a complete installation. These components are essential for reducing drivetrain friction and ensuring the chain moves smoothly across the cassette. Regular maintenance of derailleur pulleys helps prevent premature chain wear and preserves shifting accuracy. SRAM utilizes durable materials in these pulleys to withstand the grit and debris often encountered on the trail. This kit is a direct factory replacement that restores the original mechanical feel and reliability of a high-performance mountain bike drivetrain.
