Renthal 520 Twinring Heavy-Duty Rear Sprocket

The longest lasting most durable off-road sprocket you can buy developed over 5 years. The unique flat face design keeps weight to a minimum and means the TwinRing's as narrow as a regular chainwheel. Inner Ring is high strength Ultralight 7075 T6 Aluminium. Outer Ring is Electroless Nickel Coated steel. Outer is expanded at 200 °C and then fitted to inner, creating a permanent bond for the life of the sprocket

Features:

  • Inner Ring is high strength Ultralight 7075 T6 Aluminium. Outer Ring is Electroless Nickel Coated steel
  • Outer is expanded at 200 °C 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 prevent dirt build up.
  • Available for most popular dirt bikes with a 520 chain in sizes ranging from 47 to 53

I've used many sprockets over the past 30 years and this is the very best money can buy. Nice looking, tough as nails, machined to tight tolerances. Very nice.

Forget the aluminum sprockets, the composite material ensures durability and low weight at the same time. I use it to rally races, it is the best.
