A new optimized layup drops further grams from our hollow carbon arms and to stay on top of current fit trends we’ve added our first carbon 160mm crankarm length option. And our x-range gearing keeps your cadence change during a front shift to the minimum maximizing your ability to put power down. - one-piece 2x chainring results in a lighter weight stiffer more durable crankset - 29 g lighter than the previous generation - x-range gearing technology gives you more range and a smoother gear progression so you’re always in the right gear - crisp and accurate front shifts - ultra-light hollow carbon fiber crankarms - dub bottom bracket adds durability and simplicity - 50/37t 48/35t and 46/33t chainring combos available - can be upgraded to a power meter - available in 160 165 167.5 170 172.5 and 175 mm lengths
