Step 1. Bike – Road
Step 2. Select Power Meter Type
There are 8 types of power meters for your road bike. Review and select the best option.
1. Crank (Spider)
Crank-based cycling power meters are located on the cranks of the bike and measure torque using a strain gauge positioned inside the crank spider. These units require specific cranks or cranksets, but can be interchanged between bikes, depending on compatibility. A typical crank-based power meter adds approximately 150 grams to the crankset. Crank-based cycling power meters are some of the most common power meters and are the most heavily adopted system by professional athletes.
- Dependable, reliable and accurate
- You can find a crank-based power meter to fit just about any bike (road, MTB, track, cyclocross, etc.)
- You don’t have to make any compromises to your component selection. For example, you don’t have to use different pedals (as with a pedal-based power meter) or a different hub (as with a hub based power meter)
- Can cost more than some other options
- Servicing crank-based cycling power meters can be more expensive and time consuming. For example, SRM requires you to send your unit in to the factory when it’s time for a new battery
- $1,599 – $2,499
- Crank based power meters take more time to install and are generally not transferred from bike to bike
