Made of ultrastrong but light alloy, the Turbine's arms are more than up for even your most aggressive cross-country, trail, or all-mountain rides. 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 other two- or three-ring combinations. The 30mm spindle is CNC machined from 7050-series aluminum for excellent strength and solidity.
The Race Face Turbine Cinch Crank Arms are available in the colors Black, Blue, or Red, and in 170mm or 175mm lengths. The 30mm spindle is compatible with most 68/73mm bottom bracket shells. The arms do not include and chainrings, spiders, or the necessary Race Face Cinch bottom bracket, which is available for several different bottom bracket platforms.
