Q & A

The Stages Cycling officially endorsed Cannondale Si power meter allows you to transform any bike equipped with an alloy or carbon Cannondale Si chainset so you can train using power.

The first thing lot's of people ask when it comes to measuring power is; what does measuring power do? the answer is simple - power is a true metric that remains relatively unaffected by temperature, wind speed, road surface, road grade, time of day, heart rate or any other outside parameter that might affect a cyclist's performance.

Since power is the most consistent measure we have of a cyclist's effort, it's the best metric to use when tracking a cyclist's training. Power is the only measure that shows a true change in fitness or the performance of a cyclist over a period of time.

Power can also provide the most accurate gauge of real time performance, thus a power meter can serve as a rider's 'rev' limiter, ensuring that a rider puts forward their best performance and sustains it for the necessary time.

By training smarter with power you're guaranteed to get faster and able to put the hurt on your competition.
