Turbine 3x10 CranksetTurbinecranks are light enough for XC yet strong enough for AM use. The 7050alloy I-Beam crank arms have stronger pedal threads than the XT (fromthe big S of course). 24/32/42 with 170/175/180mm arm lengthoptions. Note: Please use with compatible 3x10 components.Features: Arms are carefully engineered using ultra-high strength 7050 aluminum alloy to maximize strength to weight ratio. Fully forged for maximum fatigue resistance and then extensively CNC machined for that classic Race Face look. Aggressive I-Beam profiling minimizes weight while maintaining stiffness and strength. Race Face Turbine chainrings are 100% CNC machined from super-hard 7075 aluminum to maximize wear resistance & impact strength. 'EXI' interface external bottom bracket system for easier crank installation and removal with standard tools and fully adjustable chainline. Integrated butted, forged and CNC machined CrMo EXI spindle. Incorporated crank bolt puller cap makes crank removal a snap with just an 8mm hex wrench. Comes with all new Turbine BB; fits 68/73mm shells Bearings feature new custom triple wiper seal to better retain grease & keep contaminants out. Custom 6805 16 ball retainer bearings with Titanium coated races that ensure unparalleled corrosion resistance.
