SRAM's Rival AXS E1 Crankset sits at the entry point of the road AXS hierarchy, and it inherits the same one-piece 2x chainring architecture that Force and Red use rather than a traditional spider-and-bolt setup. Integrated chainrings deliver flawless shifting in ranges that fit your needs, with the whole package coming in over 50 grams lighter than the previous generation. The crankarms are aluminum instead of the carbon used on Force and Red, which is where the price difference between the tiers actually goes.

Strategic cutouts in the crank arms shave 50 grams off compared to the previous generation, while SRAM's DUB spindle further reduces weight versus most 24 mm spindles. The DUB interface is the same across SRAM's road and mountain lineup, so bottom bracket compatibility stays consistent whether you're building a road bike, a gravel bike, or swapping cranks between platforms. The crankset is compatible with road bikes and frames that use a standard road 45 mm chainline and works with SRAM AXS 12-speed drivetrains.

Chainring options cover the two ratios SRAM offers across the road AXS lineup. The 48/35T and 46/33T chainring combinations are available , both using X-Range gearing to pair with a 10-33T or 10-36T cassette for a wider spread than traditional 11-speed road gearing. The 13-tooth gap between the rings is intentional — it keeps front shifts predictable and lets the rear derailleur handle smaller cadence adjustments without cross-chaining.... Read More
