Race Face Next SL G4 Crank Arms Parts Mountain Cranksets

Race Face Next SL G4 Crank Arms. The Race Face Next SL G4 crank arms are the lightest cranks in the Race Face line up and are a must have when your mountain bike demands the highest performance delivered with the minimum of grams. The Next SL G4 crank arms are even lighter than their Next SL predecessor plus they're stiffer thanks to the Super Alloy aluminum construction of the 30mm spline interface spindle. The Next SL G4 crank arms are also remarkably versatile due to the Cinch system interface which enables you to run a direct mount single chainring, or else use a removable spider to set up the crank arms for double or triple chainring configurations.
