All new, but nothing new.

Are you surprised that Race Face just released the world's lightest DH-rated production crankset? You shouldn't be. The British Columbia-based company has been known for pushing the limits of what materials can do, so riders can push the limits of what they can do, and in the case of the Race Face SIXC Crank Arms, everyone wins as a result.


Made in-house of ultra-high-density unidirectional carbon fiber, and formed with a proprietary hollow-molding process, the SIXC's arms are like Bruce Lee's: there are bigger ones out there, but virtually none that are stronger. The crank is based on the company's Cinch interface, which allows for the installation of both direct-mount Race Face chainrings in a huge range of available sizes, or a four-bolt spider for the installation of any others. The modular 30mm spindle interface means you can swap out the standard 68/73mm spindle for a DH-ready 83mm one, both of which are made of RF's own "super alloy" that's 20% stronger than the 7050-series alloy most commonly used in crank spindles.


The Race Face SIXC Crank Arms are available in the color Black and in 165mm, 170mm, and 175mm lengths. The arms come standard with the 68/73mm spindle. They do not include and chainrings, spiders, or the necessary Race Face Cinch bottom bracket, which is available for several different bottom bracket platforms.
