Powertap ? $$ wow Polar 525
Looking at Bike computers for another bike.
Any reason to get a computer above Polar 525?
What does the 725 or 720 have that makes it more desirable?
Mainly interested in HR, cadence, mileage.
Why is the Powertap so expensive?
The Power Tap is "expensive" because it measures power output via strain gauges within the hub, it's not just a bike computer. It's actually cheaper than it's rivals (with the exception of the Polar 725, which is just cheaper) such as the SRM, Ergomo.
It's a great bit of kit
