SRAM RED 2x Crankset E1
Product Details
The SRAM RED 2x Crankset E1 represents the cutting edge of road cycling performance, combining ultra-lightweight construction, exceptional stiffness, and advanced drivetrain technology. Designed for riders who demand maximum efficiency, this crankset features redesigned hollow carbon fiber arms that are 29 grams lighter than previous generations, delivering responsive power transfer with every pedal stroke.
The one-piece 2x chainring design improves stiffness and durability while reducing weight, creating a seamless connection between rider and drivetrain. SRAM’s X-Range gearing technology provides smoother gear progression and minimizes cadence changes during front shifts, helping you maintain consistent power output across changing terrain. The DUB bottom bracket interface adds durability and broad compatibility, while optional power meter upgrades allow riders to track performance with precision.
Available with a 160mm crank arm option, the RED 2x Crankset E1 accommodates modern fit preferences while maintaining the speed-focused performance expected from SRAM’s flagship road components.
