Spindle-based, single-leg power meter crankset for 55 MM chainline bikes
SRAM XX Eagle AXS Transmission Power Meter Spindle Crankset
The SRAM XX Eagle AXS Transmission Power Meter Spider Crankset features SRAM’s spindle-based power measurement and XX crank arms. Compatible with 55 MM chainline bikes, this XX crankset measures left-leg power, is accurate to +/- 3% and gets over 400 hours of battery life from one AAA lithium battery. In addition, these XX crank arms are full carbon, which ensures maximum stiffness while keeping weight low.
The power meter also comes loaded with features such as MagicZero, 10K Temperature compensation and is fully compatible with Flight Attendant. It works with 55 mm chainline bikes and fits chainring sizes from 30T – 36T.
Key Product Details
The SRAM XX Eagle AXS T-Type Power Meter Spindle Crankset has a Q174 spindle, uses a 3 mm offset chainring and fits 55 mm (Wide) chainlines. It will not fit bikes with a 52 mm (Boost) chainline. It requires a SRAM DUB Bottom Bracket. See Compatibility tab for more information.
The SRAM power meter measures left leg power and doubles the value to account for both legs (assumes both legs are generating the same force).
Accurate to within +/- 3%, stiff, lightweight carbon fiber crank arms, 400+ hours of battery life, AAA user-replaceable battery, ANT+ and Bluetooth compatible, 2-year warranty, auto-zero (automatic calibration). See Specs tab for more information.
Advice From Our Staff:
This power meter crankset doesn’t offer dual-sided power like the spider-based version we sell does, however at $750, it’s $200 more affordable than the dual-sided version. You also get the exact same light, stiff XX carbon cranks. We are big fans of SRAM power meters. They are reliable and are backed by a solid 2-year warranty.
Options For This Power Meter
Crank arms: 165 mm | 170 mm | 175 mm
Chainrings: 30T | 32T | 34T | 36T
