I've got 2 Elsas, one compact and one standard each on different bikes. I alternate pretty regularly for training and racing. I calibrate before each ride (the standard reads about 480 or so and the compact reads about 1451 or so, both before and just shortly into the ride). Are the different readings from each bike suspect?
To complicate matters I'm looking at a TT bike with a Rotor 3D, and the only compatible meter I can find is the Power2Max, which would make 3… I know, I know, first world problems.
