RENTHAL Twinring™ Rear Sprocket 50-Tooth Black 1230-520-50GPBK

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 manufacturing process ensures 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 Strength: Flat socket head screws provide additional strength during side impacts and prevent contact with the chain guide.
• Self-Cleaning Design: Mud grooves between each tooth prevent dirt buildup, reducing wear and maintaining optimal performance.
• Extended Lifespan: Outlasts standard all-aluminum sprockets by three times and is lighter than all-steel rear sprockets.
