What would be the best power meter option for a BSA road frame with Campagnolo Chorus and a BB30 CX frame with Ultegra? I really want true power balance too because I'm struggling with a weaker left leg having dislocated my knee twice. I want to know how much weaker. The chrous chainset weights 670g so I want something lighter really.
Maybe I'm cheaping out by not buying two powermeters but I exclusively ride the CX bike in the winter so there's not much point in having two PMs when one will be idle for half a year.
