RENTHAL Twin ring Rear Sprocket - 1540-520 Series
Introducing the innovative Twinring* Rear Sprocket, a perfect blend of performance and durability designed to enhance your riding experience. Each sprocket features an inner ring crafted from high-strength Ultralight* 7075 T-6 aluminum, renowned for its lightweight properties and exceptional strength. The outer ring is made from electro-less nickel-coated steel, providing ultimate durability while minimizing material for reduced weight.
The unique manufacturing process involves expanding the outer ring at 200°C and fitting it over the inner ring, creating an interference fit that, combined with a wave pattern, ensures a permanent bond for the lifespan of the chainwheel. This advanced design not only enhances performance but also significantly extends the life of the sprocket.
Engineered for resilience, the flat socket head screws add extra strength during side impacts and prevent contact with the chain guide, ensuring smooth operation. Additionally, self-cleaning mud grooves between each tooth effectively prevent dirt build-up, which reduces wear and tear on the chainwheel while maintaining its lightweight advantage.
Compared to standard all-aluminum sprockets, the Twinring* Rear Sprocket will outlast by three times, while still being much lighter than traditional all-steel options. This makes it an ideal choice for riders seeking both performance and longevity in their gear. Elevate your riding experience with the Twinring* Rear Sprocket, designed to keep you ahead on the trails.
