Historically the easiest place to consistently measure power on a bike was at the rear hub, which has the least input forces and is the most stable area for measurement. Although hub-based power meters were once very popular, in more recent times they have become somewhat of a rarity as pedal and crank-based power meters have largely replaced

Learn MoreAftermarket power meters like Stages are bonded to inside of the crank arms. Stages (shown above) and 4iiii are the top aftermarket brands for add-on power meters, offering kits for most popular alloy (and some carbon) crank arm brands and models. They measure the power with a strain gauge that measures the deformation of the crankarm under power.
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. The spider-based power meters attach to AXS cranksets using a simple 8-bolt interface.
If you're Training (with a capital “T”) for real, it's probably best to put your power meter-equipped bike on the trainer and use that to track performance even if you're relying on your smart trainer to control resistance or online avatars.
Most brands claim accuracy between +/- 1% for crank-based power meters, and the tolerance can go out as much as 2-3% for less expensive options. Asking how accurate you need it to be, though, is a bit of a trick question, because the real answer is “it doesn't matter” as long as you stick with the same one.
Spider-based power meters use Magic Zero technology to automatically calibrate the power meter for you, so you never need to worry about calibration! MagicZero works by continuously monitoring the torque signals from the strain gages as you ride, so you can focus on the road ahead.
If you have a smart trainer for indoor riding, capture power data straight from your power meter rather than your trainer to keep your data consistent from outside to inside. If you have a standard indoor trainer, your power meter will make it “smart” by allowing you to capture power and cadence data and transmit it to your bike computer.
