RENTHAL Twinring™ Rear Sprocket 48-Tooth Black 2240-520-48GPBK

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 innovative design includes self-cleaning mud grooves and flat socket head screws, enhancing strength and longevity.

• Dual-Material Construction: Inner ring made from Ultralight™ 7075 T-6 aluminum and outer ring from electro-less nickel-coated steel for optimal strength and reduced 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 Durability: Self-cleaning mud grooves between each tooth prevent dirt buildup, reducing wear and extending sprocket life.
• Improved Impact Resistance: Flat socket head screws provide additional strength during side impacts and eliminate contact with the chain guide.
• Longevity: Outlasts standard all-aluminum sprockets by three times and is lighter than all-steel rear sprockets.
