First Look: Race Face SIXC Cinch Chainset

Race Face rose phoenix-like from the flames a few years ago and are back to their old ways. Pete has got his hairy palms on a pair of what are being sold as ‘ lightest production DH rated carbon crankset on the planet.’ They’ll be tested among some Scottish granite over the coming months.

Cranks might not be the most exciting product on Earth, but when they’re done right they are worthy of attention. Race Face’s SIXC chainset is a name many will be familiar with from their previous top-of-the-line carbon efforts. This all-new for 2015 chainset however is a move to not only improve the previous offering, but to make this one future-proof.

  • 540g (36T DM, 165mm, 83mm spindle, w/o BB).
  • New Sinch interface allows unlimited axle/ring configurations.
  • 30mm axle.
  • £389.99 (arms only).

First impressions?

Let’s start with that confident claim that these cranks are ‘ lightest production DH rated carbon crankset on the planet.’ Light they certainly are. At 540g with the 36t direct mount ring and 83mm axle, they are one of the lightest cranks out there, not just DH rated. The set we have here is likely marginally lighter owing to the fact that the guys at Silverfish have sent a 68/73mm axle and a 32t front ring, pushing the weight ever closer to the 500g mark.

Strength can only be tested in the real world, but there is plenty of promise here. Race Face have designed these cranks to be as strong as they can be. A hollow carbon arm takes care of the positive strength:weight ratio here. The arms are all-carbon as well, no metal inserts here.

On top of all this low weight and high strength is the real selling point. While more expensive than an XX1, and similarly price to the XTR offering, the real winner here is bike compatibility. The Cinch interface isn’t unique to the SIXC, available on both their Turbine and Next SL chainsets, but it is a very smart idea. Once you have purchased the crank arms, you can change the axle width from 68/73 to 83mm or even the width fatbikes use, whatever that might be. On top of that, the removeable spider allows you to fit 3x, 2x or 1x front setups, or even mount a BMX spider for your race bike.

Having been more than used to Shimano’s offerings, crank-wise, over the last few years, the 30mm axle and accompanying BB seems large to say the least. It’s unlikely a 49kg runt will find any flex here, but it’s nice to know I’ll not be wasting any power through lack of stiffness.
