SRAM Crank Arm Assembly RED E1 DUB 175mm (BB/Chainrings not included)We’re not ones to rest on our laurels. So when we found ways to make our lightest and stiffest crankarms even lighter, we went for it. A new process 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.

29 g lighter than previous generation

8-bolt interface compatible with power and non-power AXS spiders and integrated chainrings

DUB bottom bracket adds durability and simplicity

Available in 160, 165, 167.5, 170, 172.5, and 175 mm lengths
