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
