By understanding your output on the bike, you can adjust how you train to optimize your cycling performance. 

The only thing more irresistible than the iridescent carbon crankarms is setting a new personal record, and with Force AXS, you can measure your power and make it happen. Read on to find the best upgrade path for your Force AXS bike.

Force AXS power meter options for 1x and 2x drivetrains.

2x Power Meters

A one-piece design means this 2x power meter is the lightest, stiffest, and most accurate upgrade for your Force drivetrain. The integrated power meter and chainring combo includes our ultimate Quarq D-Zero technology for right and left leg power readings, accurate to +/-1.5 percent, and our consistent 13-tooth gap on the rings for fast and reliable shifting. 

This spider-based power meter attaches to AXS cranks using a simple 8-bolt interface. Add it to your Force AXS bike in a handful of steps:

How to Install
  • Remove the driveside crankarm using a hex wrench long enough to apply the 60 Nm required to back out the fixing bolt. 
  • Remove the eight Torx T20 bolts. 
  • On the power meter, remove the battery cover, unscrew the cap, and remove the insert under the battery. Reinstall the cap and cover.
  • Lift the non-power spider or chainring assembly off the crank, and replace it with the power meter version.
  • Install the eight new Torx T20 bolts supplied with the power meter and torque them to 4 Nm in an alternating sequence.
  • Reinstall your crankset, torque the 8mm hex fixing bolt to 54 Nm, set your preload, and go ride. 

Now you're ready to see just how many watts you can put down during your next townline sprint.
