Renthal Twinring Rear Sprockets - Red

Unique flat face design keeps weight to a minimum and means the TwinRing is as narrow as a regular chainwheel. 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.
