BIKE POWER METERS BUYER'S GUIDE KIT ZONE
Put simply, the power you put into riding a bike is what you get back on the road. And monitoring that power has many benefits for triathletes – the biggest of which is pacing. When using a power meter paired with a bike computer, you can monitor your output and make sure you don't push too hard, which could otherwise negatively affect your run performance.
Another benefit is the ability to spot early signs of fatigue. By assessing actual work done,inaccurate metrics like average speed or feel, you can catch signs that your body isn't quite on it. And unlike heart rate, which can be affected by things such as nerves, weather or cardiac drift, power is unaffected by external variables.
