SRAM Rival E1 DUB Crank Arms Without Bottom Bracket

SRAM Rival E1 DUB crank arm, with aluminium arms optimised for stiffness and weight, suitable for riders using a SRAM AXS drivetrain. It is sold without a bottom bracket: a DUB bottom bracket must be purchased separately. The available colour is black.

Length is the main choice: sizes range from 160 to 175 mm, and the spindle is available in standard or Wide versions. Choose the size based on your height and pedalling style. The 8-bolt mount is compatible with AXS spiders, with or without a power meter, and with integrated cranksets. The DUB bottom bracket adds durability and simplicity.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
