Accurate, Durable, Consistent
The power meter benefits from Quarq’s 10+ years of experience designing power meters.
The Quarq SRAM XX1 Eagle DUB Power Meter is the ultimate spider-based power meter for your mountain bike: accurate, durable and consistent in all conditions. The power meter comes loaded with features such as MagicZero, whereby it automatically calibrates (offsets) as you ride. You also get 10K Temperature compensation which ensures the power meter stays accurate regardless of changes in temperature. The XX1 power meter runs for 200 hours on a single CR2032 battery and comes with a full 2-year warranty.
This power meter works with SRAM XX1 Eagle DUB 8-bolt cranksets. It comes in both Boost and Standard chainline configurations.

Crank arms: 165 mm, 170 mm, 175 mm
You can purchase the power meter with or without crank arms.
Chainrings: 30*, 32, 34, 36, 38
You can purchase the power meter with or without chainrings.
*The Quarq SRAM X-SYNC 2 12-Speed Chainring is not offered in a 30T. Therefore, for 30T applications, we ship a Wolf Tooth Components 1x 104 BCD MTB Chainring.
The power meter works with SRAM XX1 Eagle DUB 8-bolt cranksets. We recommend the use of Quarq SRAM X-SYNC 2 12-Speed Chainrings for best performance, however any 104 BCD chainring may be used (32T or larger with the exception of the 30T Wolf Tooth ring mentioned above).
