In competition, every little advantage counts - a merciless hunt for even lighter, stiffer, stronger and more durable material. In order to develop the best possible groupset, SRAM has checked the crankset again and completely revised it. This XX1 Eagle Carbon Tuned crankset for Boost frames is currently the lightest, stiffest and strongest from SRAM. DUB technology contributes to this by simplifying the interaction of bottom bracket and crank axle and raising durability to a new level. A DUB crankset is simpler, more universal and more durable.
