SRAM Rival E1 12-Speed 2x DUB Crankset

The SRAM Rival 12-speed crankset is an aluminum 2x road crank on SRAM DUB, with an integrated aluminum chainring built around SRAM's X-Range gearing. It is a clean way to put modern 12-speed double gearing on a road or all-road bike.

You choose between 46/33T and 48/35T rings, each offered in 160, 165, 170, 172.5 and 175mm arms. Chainline is 45mm and the DUB bottom bracket is sold separately, so plan your frame's bottom bracket alongside the crank.

Who It's For

• Road riders building or upgrading a 12-speed SRAM 2x drivetrain
• Riders who want shorter arm options down to 160mm
• Bikes with 135/142 road disc rear spacing
• Consider a different crank if your frame needs GXP, BB30 or a 1x ring

What to Look For

• Spindle interface: SRAM DUB. You will need a DUB bottom bracket for your frame; it is not included.
• Gearing: 46/33T for lower climbing gears, 48/35T for a taller top end. Both are 12-speed.
• Crank length: 160 to 175mm in 2.5mm and 5mm steps; choose by fit.

Key Features

Aluminum arms. SRAM shapes the arms to put material only where it is needed for stiffness to weight, and states the package is over 50 grams lighter than the previous generation.

DUB spindle. The DUB spindle is SRAM's current bottom bracket platform. The bottom bracket is sold separately, which lets you choose the version for your frame's shell.

Integrated 2x chainring. The aluminum double ring mounts via SRAM's 8-bolt direct mount interface and uses X-Range gearing, which SRAM designs for wider range and a smoother progression between gears. Chainline is 45mm.

Fit options. Black finish, 9/16" pedal threads and five arm lengths, including 160mm for riders who benefit from a shorter crank.

Rider Intent Summary

• Biggest strengths: 12-speed 2x gearing in two ratios with a wide spread of arm lengths.
• Tradeoffs: DUB bottom bracket sold separately; integrated rings mean the ring set is replaced as one unit.
• What makes it different: An integrated 8-bolt direct mount double ring rather than a bolted ring pair.

Victory's Take

At Victory Bicycle Studio we match 46/33T or 48/35T to how and where you ride, then confirm crank length during a fit. If you are unsure which DUB bottom bracket your frame takes, we can sort that out with the order.
