SRAM Rival E1 AXS XPLR/Wide Power Meter Crankset
The SRAM Rival E1 AXS XPLR Power Meter Crankset is an affordable power meter crankset for gravel and adventure bikes. This spindle-based power meter measures power from the left leg and is +/- 1.5% accurate. It uses a replaceable AAA battery featuring 400+ hours of battery life which is perfect for long adventures without access to charging. In addition, this power meter crankset uses a 1x chainring. This eliminates the need for a front derailleur which simplifies and saves weight on your bike’s drivetrain.
This power meter supports both ANT+ and Bluetooth SMART for easy pairing with your favorite devices. It’s IPX7 waterproof and backed by a 2-year warranty for added peace of mind. The lightweight aluminum crank arms are built for durability on rough terrain, with cutouts to reduce weight without sacrificing strength.
