The SRAM RED AXS Power Meter Crankset E1 delivers pro-level performance in a lighter, more refined package. At 29 grams lighter than its predecessor, it’s built for cyclists who want precise data on their rides. The spider-based power meter is fully integrated into the chainring for a clean look and measures power with ±1.5% accuracy, including left/right leg balance—ideal for riders who value data-driven training. And thanks to a weatherproof design, your numbers will stay consistent no matter the conditions.

With SRAM’s X-Range gearing, you get a wider range with tighter jumps, making it easier to find the perfect cadence whether you're climbing or sprinting. Add in the proven DUB bottom bracket interface, and you've got a lightweight, stiff, and low-maintenance setup that delivers crisp shifting and all-day reliability.
