Unique flat face design keeps weight to a minimum and means the TwinRing is as narrow as a regular chainwheel. Flat socket head screws and additional strength to the chainwheel during side impacts. Self-cleaning mud grooves between every tooth on both sides help prevent dirt build up.

• Inner ring is high-strength, ultralight 7075-T6 aluminum
• Outer ring is electroless nickel coated steel, 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
• Available for most popular dirt bikes with a 520 chain in sizes ranging from 47 to 52 teeth
