SRAM XX Eagle AXS Transmission Power Meter Spider Crankset
The SRAM XX Eagle AXS Transmission Power Meter Spider Crankset features SRAM’s new integrated thread mount power meter spider with XX crank arms. This is SRAM’s most accurate mountain bike power meter crankset ever made! It is also one of it’s lightest (just behind the SL version). The XX Eagle AXS T-Type Power Meter Crankset uses an all-new spider-based design with a proprietary thread-on chainring mount system. This thread mount system allows for a lighter, easier to use power meter. The power meter also comes loaded with features such as MagicZero, 10K Temperature compensation and is fully compatible with Flight Attendant.
The power meter gets 200 hours of battery life on a single CR2032 battery and comes with a full 2-year warranty. It works with 55 mm chainline bikes and fits chainring sizes from 32T – 38T.
Key Product Details
Compatibility:
This power meter 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.
Power Measurement:
The SRAM power meter measures power at the spider and is therefore able to measure power from both legs.
Key Features:
Dual-leg power measurement, accurate to +/- 1.5%, lightweight carbon crank arms, 200 hours of battery life, CR2032 user-replaceable battery, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration). See Specs tab for more information.
Advice From Our Staff:
This is one of the nicest MTB power meter cranksets we offer. It is not cheap, but you get an accurate, dual-sided power meter mounted to light, stiff carbon fiber crank arms. We are big fans of SRAM power meters. They are reliable and are backed by a solid 2-year warranty.
