SRAM RED E1 Crankset Power and precision meet on the road with the SRAM RED E1 Crankset, turning every pedal stroke into forward momentum. Its hollow carbon fiber arms drop 29g from the previous generation, delivering a stiffer, lighter platform for climbs and accelerations, and the 45mm chainline ensures optimized shifting performance. With X-Range gearing, front shifts are crisp and predictable, keeping you in the optimal gear as you ride. Who is this for? Riders who demand elite-level performance from their road bike—racers chasing every watt, long-distance grinders, and enthusiasts who value smooth, reliable shifts and a gear range that covers steep climbs and fast flats. specifications details Number of Chainrings Double (2x) Drivetrain Speeds 12 Chainring BCD Direct Mount SRAM (8-bolt) Chainline/Hub Compatibility 135/142 Road Disc Hubs < 415 mm Chainstay Crank Intended Use Road BB Included No Pedal Spindle 9/16" Spindle Interface Type SRAM DUB Arm Material Hollow Carbon Fiber Each item is professionally packed and shipped next day.
