SRAM RED Crank Arm Assembly E1 DUB
SRAM’s lightest and stiffest road crankarms have been refined to save further weight, with a new hollow carbon arm process reducing weight by 29g versus the previous generation.
Designed for modern fit requirements, the range now includes 150mm and 155mm crankarm options alongside the existing lengths. The 8-bolt interface provides compatibility with power and non-power AXS spiders, as well as integrated chainrings, while SRAM’s DUB system keeps setup simple and durable.
