Sram Red Axs Crankset

The sram red® crankset leverages a pivotal design innovation: smaller chainrings and a wider cassette range. This leads to smoother and faster shifting up front and more useful gearing for today’s riders. The new configurations improve cadence and efficiency while also delivering shifts that are crisp clean and quick—every time. - speeds: 12 - bb compatibility: all sram road dub bbs gxp/pf gxp 68mm - chainring size: 46/33 48/35 50/37 - crank arm length: 165mm 167.5mm 170mm 172.5mm 175mm - chainline: 45.0mm - bb spindle interface: 24mm dub - chainring material: aluminum - guard: no guard - bolt circle diameter (bcd): direct mount (dm) - crank arm material: carbon - color (crank arm): natural carbon
