Renthal 520 TwinRing Rear Sprocket 48T Black

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 aluminum
• Outer Ring is electroless nickel coated steel that's expanded at 200 degrees Celsius and then fitted to inner ring, 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
• Made in the UK
