SRAM XX1 Eagle Power Meter Boost Crankset 32T Info
The SRAM XX1 Eagle Power Meter Boost Crankset 32T sits at the top of SRAM's mountain drivetrain hierarchy, combining the proven XX1 Eagle platform with an integrated power meter for riders who want accurate wattage data without bolting on aftermarket hardware. It's a single-ring crankset built around a 32T chainring and Boost spacing, designed for 12-speed Eagle drivetrains. If you're training with data or simply want to understand your output on the trail, this is where precision meets proven MTB performance.
SRAM's power meter technology is built directly into the left crank arm, measuring power through strain gauges and transmitting via ANT+ and Bluetooth to your head unit or cycling computer. The XX1 Eagle lineage brings a carbon construction that keeps weight well below what you'd find on mid-tier options, and the Boost spindle spacing positions the chainline correctly for modern short-travel and trail geometry frames. Available in 170mm and 175mm crank arm lengths, it's adaptable to a range of rider proportions and bike setups. The 32T single chainring pairs with a narrow-wide tooth profile designed to retain the chain across rough terrain without a guide.

Design Benefits
- Integrated power data without compromise. Because the power meter is built into the crank arm rather than added as a separate unit, there's no additional hardware to mount, pair, or maintain separately — the setup is cleaner and the drivetrain weight stays low relative to most aftermarket power meter solutions.
- Eagle-grade durability across demanding terrain. The XX1 Eagle platform has a long track record on technical singletrack, enduro courses, and long backcountry days. The narrow-wide 32T chainring is designed to hold the chain securely under the kind of vibration and lateral force that dislodges chains on less refined setups.
- Broad compatibility with modern mountain bike geometry. Boost spacing has become the standard for trail and enduro frames, and the DUB spindle interface spans a wide range of bottom bracket shells — making this crankset a straightforward fit for most contemporary builds without requiring obscure adapters.
