SRAM Rival XPLR E1 Crankset

The SRAM Rival XPLR E1 crankset is an aluminium gravel crankset with a 42-tooth chainring and a DUB bottom bracket. It is designed for riders fitting a 12- or 13-speed drivetrain to a gravel bike who want a good balance of stiffness and weight. The 47.5 mm chainline is designed for Full Mount rear derailleurs.

The DUB bottom bracket uses a simpler, more durable interface, and the long spindle is compatible with both road and MTB standards. The crankset supports 135, 142 and Boost rear hub spacing, so you can check your frame before purchasing. It is available only in black. If you want to change the gearing, the direct mount interface accepts chainrings from 38 to 46 teeth.

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.
