The Story
The SRAM RED E1 Crank Arm Assembly represents the pinnacle of carbon engineering, achieving a 29g weight reduction over its predecessor. Utilizing a refined hollow carbon process, these arms are the lightest and stiffest in SRAM's lineup, designed to maximize power transfer. To meet modern ergonomic trends, the E1 series introduces a 160mm length option, ensuring a high-performance fit for a wider range of riders.
Built for versatility and longevity, the assembly features the proven 8-bolt interface, making it compatible with both powered and non-powered AXS spiders or integrated chainrings. The DUB bottom bracket spindle provides superior bearing durability and a simplified interface across various frame standards. This crank arm assembly is the definitive choice for riders looking to shave every possible gram without sacrificing structural integrity.
