Οπίσθιο γρανάζι RENTHAL Twinring™ HONDA CR 125 (Μαύρο-Κόκκινο)

Twinring™ Rear Sprocket

• Inner ring is the same high strength Ultralight™ 7075 T-6 aluminum used for the standard Renthal sprocket
• Outer ring is electro-less 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 and then fitted over the inner; this interference fit combined with the wave pattern ensures a permanent bond for the life of the chainwheel
• The flat socket head screws add additional strength to the chainwheel during side impacts and eliminates contact with the chain guide
• Self cleaning mud grooves between each tooth prevent dirt build upand reduce chainwheel wear and weight
• Will outlast a standard all aluminum sprocket by 3 times, yet is much lighter than an all steel rear sprocket
