Power meters are a great way to improve your bike training and now they're less than a nice pair of aero wheels. If you're looking to add power to your bike without breaking your piggy bank, check out the Quarq RIKEN 10R Power Meter Crankset - BB30. Featuring Omnical, which means you can run whatever chainrings you want and not have to recalibrate your power meter, the RIKEN is just a fancy as the more expensive power meters, just without the lightweight crank arms. With the battery placed so it's easily accessible, you can now change it on your own. The Quarq RIKEN is the power meter for everyone.
