I have some significant power differences between left and right legs that are contributing to some ongoing muscle/tendon issues that are being addressed by physical therapy and some strength and flexibility training. As part of addressing these ongoing issues I did a bike fitting that included a torque analysis that confirmed the power differences identified in physical therapy. The fitter recommended using a left+right power meter to get some ongoing feedback about progress with improving the balance in power output. I'm thinking of using the new Vector 3, but not too enthused about switching from my Speedplay pedals. But, I see this as a worthwhile investment?
