About This Product: Race Face Cinch Carbon Crank Arms

Introducing the lightest production DH rated carbon crankset on the planet. Designed, tested and manufactured in Raceface's Canadian facility with US sourced carbon and aluminum. SIXC combines proven Race Face proprietary hollow arm technology with new Cinch interface and the renowned strength to weight ratio of the original SixC crankset making it ideal for BMX.

Features

  • Completely redesigned for 2015.
  • The crank arms are completely hollow with all unnecessary material being removed from the center core - no internal aluminum spine.
  • Industry-standard 30mm spindle with Cinch spline interface. The spindle is CNC machined from a newly commercialized aluminum 'super alloy' that is 20% stronger than 7050 alloy (the alloy commonly used in this application).
  • Removable spider offers the ability to convert between existing chainring standards while remaining flexible to future developments.
  • Custom BMX specific spindle and spider (104 BCD)
  • Chainline - 47mm
  • Pair with one of the new 30mm Raceface bottom brackets to fit any bottom bracket shell-style (PF30, Euro, BB86/92) or if you have a BB30 frame, any BB30 bottom bracket will work
  • Weight - 620 grams w/o BB
