SRAM XX SL Eagle AXS Transmission Power Meter Spider Crankset

The SRAM XX SL Eagle AXS Transmission Power Meter Spider Crankset features SRAM’s new integrated thread mount power meter spider with XX SL (Super Light) crank arms. This is SRAM’s lightest, most accurate mountain bike power meter ever! 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 both 52 mm and 55 mm chainline bikes and fits chainring sizes from 32T – 38T.

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 super 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.
