Renthal Twinring Heavy-Duty Rear Sprockets
$0.00 - $229.95
Inner ring is the same high strength Ultralight™ 7075-T6 aluminum used for the standard Renthal® sprocket. Outer ring is electroless nickel-coated steel for ultimate durability and is designed with the minimum amount of material to keep weight down. The outer ring is expanded at 200 °C (329 °F) and then fitted over the inner; this interference fit combined with the wave pattern ensures a permanent bond for the life of the chainwheel. Flat socket-head screws add additional strength to the chainwheel during side impacts and eliminate contact with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt buildup and reduce chainwheel wear and weight. Will outlast a standard all-aluminum sprocket by three times, yet is much lighter than an all-steel rear sprocket.
