PowerTap's G3 Enve SES 3.4 Wheelset is an invaluable tool to monitor and maximize every ride. With Enve's light and fast 35/45mm-deep front/rear carbon rims, PowerTap's choice aluminum G3 hubs and DT Swiss Aerolite spokes, these hoops cheat the wind for free speed. Plus, the PowerTap G3 rear hub measures watts for the ultimate in data during training and racing. Plus, its convenient Ant+ wireless transmission sends your critical training information to any Ant+-compatible head unit (sold separately). PowerTap readings are accurate to within +/-1.5%.
By now you've probably seen friends riding with fancier-than-normal computers and strange new hubs, cranks or pedals on their bikes and found out they're riding with power meters. You may also have overheard cyclists and coaches talking of "power" and "watts." Or maybe you've read of the amazing wattage output of professional cyclists.
We're not surprised. Power measurement is the most objective, reliable measurement of cycling output, and we're here to explain how it works and help you decide if you should join the most exciting revolution in cycling since shifting brake levers.
It also has a lag in catching up to the muscular effort of pedaling. And, while heart rate increases at a rate proportional to pedal power in a controlled lab environment, it rarely does so on the road or trail. Heart rate also has high susceptibility to temperature, fatigue, altitude, caffeine intake, time of day and more, making it an imprecise measure of performance on a given day and a limited tool for comparing multiple workouts.
|Watts Are Better
Watts are better for a number of reasons, including:
Watts are objective, not dependent on the varying factors of your body or the weather. If you held 305 watts for 30 minutes on April 8, and then you churned out 318 watts for a 30-minute period a month later, you know you are improving.
Once you have this number you can compare it to get an apples-to-apples comparison and see how you're doing related to other cyclists (chart). And this will give you an idea what level you need to get to to improve.
Finally, you'll be able to track your fitness and improvement over a wide array of new levels. If you've enjoyed measuring your average speed on your favorite courses, you'll love being able to measure effort, calories, time in various zones, the intensity factor of the ride and much more.
TSS takes IF into account to provide an even better big-picture measurement of training stress. By taking IF and duration into account, TSS can be used to quantify your overall training load. By then gradually increasing TSS for several weeks and dropping it during rest weeks, you can pinpoint overload training like never before. Or, if serious training isn't your goal, you'll be able to gauge fatigue like never before. If you have trouble sleeping or find yourself snapping at your relatives, a quick check of TSS will show you if overtraining is to blame.

This is one of the best things I have ever purchased for my bike. It made a huge impact on the way I ride my bike every time I ride it. Not to mention the fact that it made me faster and look cooler immediately.
