7075-T6 Aluminum 50T Sprocket Blue

Description

• 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 designed with the minimum amount of material to keep weight down
• The outer ring is expanded at 200°C 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 setscrews add additional strength to the chainwheel during side impacts and eliminates contact with the chain guide
• Self cleaning mud grooves between each tooth prevent mud 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
