"What gets measured, gets done!". Simply stated, power measurement takes the guess work out of your training. You wouldn't go to the gym and randomly place unmarked weights on a bar hoping to "perceive" how much weight you were lifting. That would not only be dangerous, it would be a waste of time. Trying to gauge your on-the-bike training by any means other than power is dangerous (to your performance on race day) and also, likely, a waste of your valuable time and energy. The fastest racers in the world in EVERY cycling discipline incorporate power to ensure they get the most out of their training and so should you! We currently partner with Powertap, offering power hubs as options in any of our road our mountain wheelsets. Powertap has a proven track record of offering industry leading accuracy, quality, and affordability when it comes to power measurement.
