For SRAM XX1 Eagle Boost 148 (52mm chainline).
Use the SRAM XX1 Eagle Power Meter Spider to upgrade a legacy SRAM XX1 Power Meter to the DZero platform.
The Eagle Power Meter Spider uses the 8-Bolt crank to spider interface. It is compatible with power meter crank arms only.
The DZero platform embodies 10 years of Quarq’s technology advances and adds new features such as dual Bluetooth low energy and ANT+ wireless data transfer, and the Qalvin BLE app. The companion X-SYNC 2 chainrings are designed specifically for Eagle chains and drivetrains. SRAM’s Eagle groupset and an XX1 Eagle Power Meter Spider are a winning combination for mountain bikers who want to soar.
