Keep in mind that your L/R balance can change depending on fatigue, cadence, power level, position on the saddle (do you creep up during climbs for example,) incline, back/hip angle, or any combination of those. It can also skew if you race a lot on courses with only right hand or left hand turns like crits.RossLB wrote: ↑Tue Apr 30, 2019 2:41 amIt really depends on how far out your left/right balance is. Mine is about 54/46. If I used the left power meter on one bike and the right on another bike, they would be different by 16% (108% vs 92%), and both would be inaccurate by 8% but in different directions. This would be too unreliable for training purposes. But if you are much closer to 50/50 it might be less of an issue.
IMO unless one is super cash strapped and just getting into structured training, they should skip single-sided PMs and wait until they can afford something that measures total power or dual-sided power. Assiomas are just US$650.
