When SRAM found ways to make their lightest and stiffest crank even lighter, they went for it. A new optimized layup drops 29g from the hollow carbon arms. The X-Range gearing technology minimizes cadence changes during front shifts, maximizing your ability to put power down. Plus they're offering more crankarm lengths than ever before to ensure this crank works for you.
