Power meters measure the actual power (in watts) you're producing while riding. Unlike heart rate or speed, power is a direct and consistent indicator of your performance—making it an essential tool for structured training and race-day optimisation.

Types of Road Power Meters

Crank-Based

• Installed in the crank arm or spider, these are highly accurate and common among pros.
• Offer consistent power data, often from both legs.
  

Pedal-Based

• Easy to install and transfer between bikes.
• Some models provide dual-sided metrics for detailed analysis.
  

Hub-Based

• Located in the rear hub—reliable but less common today.
• Great for those who want “install-and-forget” functionality.
  

Chainring-Based

• Integrated into the spider or chainrings.
• Accurate and discreet, but harder to swap between bikes.

Key Features to Look For

• Accuracy – Look for ±1.5% or better to ensure reliable data.
• Battery Life – USB rechargeable or coin cell; both offer weeks to months of use.
• Dual-Sided Measurement – Helpful for identifying left/right imbalances.
• Connectivity – Ensure compatibility with ANT+ and Bluetooth for easy data transfer.
• Durability – Waterproof ratings (like IPX7) matter for all-weather reliability.

How Power Meters Help You Train

Set Accurate Training Zones

• Base your training on power zones rather than perceived effort or heart rate.

Track Progress Over Time

• Monitor your FTP (Functional Threshold Power) and watch it improve.

Train Efficiently

• Avoid overtraining or undertraining by using real performance metrics.

Improve Race Strategy

• Learn how to pace yourself effectively over various race distances.

FAQs

1. Are power meters worth it for road cycling?

Absolutely—power meters provide accurate, consistent data that helps cyclists of all levels train smarter and race more effectively.

2. Can I install a power meter myself?

Yes—pedal- and crank-based power meters are generally user-friendly and can be installed with basic tools.

3. What's the difference between single- and dual-sided power meters?

Single-sided meters measure power from one leg and double it, while dual-sided meters provide separate data from both legs for more accurate analysis.
