Stages Ultegra 6800 Gen 2
1 / 5
Worse than worthless. Stay away.
I found out the hard way that reading power on one side is not a good idea; unless you confidently know, based on a proper lab test or by using a much more expensive proper separate left/right capable unit for some time, that your leg's power difference is negligible. In my case, power from the Stages is off up to 80 (!) watts, depending on the zone. Training with this is the best thing you can do to give the competition a good advantage. And potentially develop some health problems. Connection range is extremely short and power readings constantly drop. For many people this won't be an issue though, because they are off anyway. Battery life of my unit is somewhere between 10 and 20 hours. 'Customer support' simply ignores you after the initial support ticket is opened.
