If you intend to ride steep mountains on your roadbike, are you sure your gears match your strength and weight?
WattsMyGear can calculate how many watts are required, in relation to your weight, your cadence, your wheel size, your gears, and the intended climb.
You change the gears in the app, until you find a watt result that matches your strength.
The gear combination you have dialed into the app, is what you should install on your bike. Get this sorted out BEFORE you get to the mountains!
