Renthal Twinring Rear Sprocket 520-50t

The Renthal Twinring™ rear sprocket provides the ultimate combination of light weight and exceptional durability. Engineered for performance and longevity, this sprocket is a must-have for serious riders.

Description

The Renthal Twinring™ rear sprocket features a unique two-piece design. The inner ring is machined from Renthal's high-strength Ultralight™ 7075 T-6 aluminum, the same material used in their standard sprockets, ensuring minimal weight. The outer ring is constructed from electro-less nickel-coated steel for maximum durability. Designed with the minimum amount of material to further reduce weight, the outer ring is expanded at 200°C and then fitted over the inner ring. This interference fit, combined with a wave pattern, creates a permanent bond that lasts the life of the sprocket. Flat socket head screws provide additional strength, especially during side impacts, and prevent contact with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt buildup, reducing chainwheel wear and weight. The Renthal Twinring™ sprocket lasts up to three times longer than a standard all-aluminum sprocket, while remaining significantly lighter than an all-steel rear sprocket. Upgrade to a Renthal Twinring™ rear sprocket for improved performance and extended service life. This 520 chain size, 50-tooth sprocket is ideal for riders seeking maximum power transfer and durability.
