Know Your Powers

You can learn a lot about yourself with a power meter. The first thing most people learn is that without a power meter you can't accurately gauge how strongly you are riding. Some days you feel weak, but the power meter numbers tell a different story—one of consistent endurance. Or, you may feel strong and fresh, when in reality, your power meter reveals that you just have a light, steady tailwind giving you a push. 

Here's a short list of major benefits made possible with a power meter:

  1. TRAINING EFFICIENCY — Greater training gains in less time? Yes, please! Power meters track power output so you can perform repeatable interval efforts instead of going too soft and slowing your training progress, or too hard and burning yourself out. Plus, your loved ones will also appreciate the additional free time you'll have to spend with them.
  2. UNDERSTAND YOUR CAPABILITY — Are you ready for that big ride or race? An accurate power meter removes any doubts and replaces it with reliable data you can trust. Be confident in the knowledge that your fitness improvements are real.
  3. TRACK TRAINING PROGRESS — What gains are you making? Use power meter data to know when you are ready for the next stage in your training. 
  4. MANAGING TRAINING STRESS AND RECOVERY — If you are dedicated to training hard, you can pretty much guarantee that you will overtrain at some point and sabotage your hard-earned progress. Power meters help you to know when you need to rest to keep the gains you've worked hard for.

Another benefit to consider is that by upgrading your bike to a power meter, you can continue to use the trainer you likely already have while gaining power measurement capability when riding indoors! This gives you access to virtual riding platforms like Zwift. 


Power meters attach to AXS cranksets using a simple 8-bolt interface. To install one, remove your driveside crank arm using a hex wrench long enough to apply the 60 Nm of force required to back out the fixing bolt. 

Then remove the eight Torx T20 bolts that attach the Force crank spider or RED chainring assembly to the crank. If you are upgrading a Force crankset, we recommend removing the chainrings using a Torx T30 wrench before removing the eight spider fixing bolts.

Force eTap AXS Power Meter

Lift the non-power spider or chainring assembly off the crank and replace it with the power meter version. Install the eight new Torq T20 bolts supplied with the power meter and torque them to 4 Nm. If you have a Force eTap AXS crankset, now install the chainrings and torque the four Torx T30 fixing bolts to 12 Nm.

Reinstall your crankset and torque the 8mm hex fixing bolt to 54 Nm. Just be sure to place the chain on the small chainring before doing this.

The last thing to do is to install the power meter battery and then follow the instructions for your computer head unit to pair your power meter to the device.
