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.

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.
