You've debated getting into fat biking for some time now, and the short winter has you all the more tempted as the ski season has graced you with little snow, and sub-par conditions -- but just enough moisture to make the trails unrideable on your standard 2. 2-inch wheels. When you're ready to bite the bullet and build up a trusty chubby-steed, snag a pair of the Race Face Turbine Fat Bike Crank Arms to bring light functionality to your plus-sized workhorse. With precision machining to exact standards, these crank arms are perfect for pairing with the Race Face direct-mount chainring of your choice, so you get to pick the optimal gearing for the rides ahead of you, or swap on a whim when you're ready for change. Just like the standard Turbine, the Turbine Fat Bike Crank Arms are forged and machined out of high-strength 7050 aluminum and utilize Race Face's Cinch System interface for maximum fatigue resistance and power transfer, with a huge variety of gearing options and compatibility with most bottom bracket standards. The Cinch system has the unique ability to convert between direct mount and bolt-on chainrings with a separately sold removable spider for exceptional flexibility of chainring choices.
