Looking to pick the collective brain. I’m seriously thinking about adding power meters to my 'bent trike. I’m not looking for anything super accurate. Just good enough to give an indication of how I’m doing. I use TrainerRoad for indoor rides. For those rides, power is calculated by speed and the power curve for my double overdrive trike rollers. What I’m wondering is, is whether or not a single sided crank based meter is going to do the trick. I don’t cringe at the thought of $3-400. $1000 makes me flinch.
