Renthal 2240-520-51GPSI Twinring Heavy Duty Rear Sprocket - 51T

Material: Aluminum
Sprocket Position: Rear
Sprocket Size: 520
Sprocket Teeth: 51

Unique flat face design keeps weight to a minimum and means the TwinRing is as narrow as a regular chainwheel. Inner Ring is high strength Ultralight 7075 T6 Aluminum. Outer Ring is Electroless Nickel Coated steel. Outer is expanded at 200C and then fitted to inner, creating a permanent bond for the life of the sprocket. Precision CNC machined to extremely tight tolerances. Flat socket head screws add additional strength to the chainwheel during side impacts. Self-cleaning mud grooves between every tooth on both sides help prevent dirt build up.
