If your ALLIED comes equipped with a SRAM Red AXS or Force AXS 1x drivetrain, simply replace your stock spider with this unit and you'll be training with power. The swap is simple -- it's just eight T20 Torx bolts.

Your wattage data will be accurate within /-1.5% and won't be affected by climate conditions during a ride. The power balance measures left and right legs separately, and it uses a common CR2032 battery that last for 200 riding hours and changes without tools.

Since this spider is part of SRAM's AXS electronic integration platform, components connect through a simple-to-use app, making it simple to monitor battery status and perform firmware upgrades. Information is sent to your smartphone, tablet, or head unit via Bluetooth Low Energy or ANT connection.
