Renthal TwinRing Rear Sprocket 48T Black 520 Pitch 1540-520-48GPBK

RENTHAL Twinring™ Rear Sprocket 48-Tooth Black 1540-520-48GPBK

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 is designed to withstand the rigors of off-road riding while minimizing weight. The unique interference fit and wave pattern ensure a permanent bond between the rings, enhancing longevity and reliability.

• Durable Construction: Ultralight™ 7075 T-6 aluminum inner ring paired with electro-less nickel-coated steel outer ring for maximum strength and minimal weight.
• Permanent Bonding: Outer ring expanded at 200°C and fitted over the inner ring, creating a permanent bond for the sprocket's lifespan.
• Enhanced Impact Resistance: Flat socket head screws provide additional strength during side impacts and prevent contact with the chain guide.
