RCF001R Race Face SixC Crank Arms

The Race Face SixC Crank Arms are the lightest DH arms in the universe. So, if you’re looking for Earth’s version of indestructible crank arms, but you’re also trying to keep the weight to a minimum, there’s no reason to look anywhere else. This is due to Race Face’s ultra-high-density unidirectional carbon fiber, which is shaped into the SixC crank arms with its proprietary hollow-molding process.

There’s even more to these crank arms than that. The SixC uses Race Face’s Cinch system to make it the most versatile crank setup in existence. Imagine interchangeable spiders, limitless ring combinations, a 30mm alloy spindle and compatibility across all relevant frame standards. That means, unless it’s a discontinued model from a brand that went out of business 30 years ago, your frame will happily accept the Race Face SixC crank arm setup with the drivetrain that you want to run.

  • Industry’s lightest DH-rated crankset
  • Ultra-high-density unidirectional carbon fiber
  • Proprietary hollow-molding process
  • Cinch interface

Unanswered Question

Considering buying these cranks.
Which raceface spindle does this crank set include?
Would be helpful with determining chain-line and q factor from the information provided here> http://www.raceface.com/comp/inst/Crank_Q-factors_and_chainlines.pdf


Light, strong, and stiff

So far no issues with these. They're on my DH bike but weigh little enough for your am bike as well. I paired them with the race face crank boots for some extra protection and so far they are still in great shape. Wish you could get a King Bottom bracket for them but that's about my only gripe.

Unanswered Question

How do these compare to the RaceFace SL cranks? I was looking to get those for my Trek Farley

Hi, I want to know if the shaft size is 83mm

Where to start...the RF SIXc cranks are awesome! They're burly enough to hold up to full on DH riding but come in at a weight that rivals that of many carbon XC cranks, partly due to the direct-mount chainring setup. If direct-mount rings aren't your cup of tea, however, RF also makes a direct-mount spider, making the SIXc cranks incredibly versatile. Installing the chain ring is a cinch, simply using a Shimano/ISIS bottom bracket tool (Park Tool# PAR0063).

It's worth noting that the cranks come with the rubber crank boots (black) to protect them from jealous rocks. Unless you want to spice it up with a different color, save the money you were going to spend on the crank boots and take your muse on a date to somewhere fancy like Applebee's.
