The XX SL Eagle AXS Transmission Powermeter crankset features our new XX SL crank arm with an integrated powermeter that records precise power values and transmits them to your bike computer. Thanks to the new crank spider design, this is our most accurate and powerful powermeter yet. Our new crank spider design uses a proprietary chainring attachment system, allowing us to reduce weight without compromising reliability. The dual-sided power measurement system calculates total wattage, is unobtrusive, lightweight, and has unbeatable battery life. Additionally, it is compatible with the RockShox Flight Attendant system, enabling all AXS-capable components to connect seamlessly. The uncompromising and powerful data transmission gives you an edge over the competition.
