RENTHAL Twinring™ Rear Sprocket 48-Tooth Silver 1540-520-48GPSI

The RENTHAL Twinring™ Rear Sprocket combines advanced materials and engineering to deliver exceptional performance and durability. Featuring a high-strength Ultralight™ 7075 T-6 aluminum inner ring and an electro-less nickel-coated steel outer ring, this sprocket offers a lightweight yet robust solution for off-road enthusiasts. The innovative design includes self-cleaning mud grooves and flat socket head screws, enhancing longevity and reducing maintenance.
