Hi there. This is my first post. Hope I haven't screwed it up. We have a Cateye Mity 3 (also says ccMT300). on the stoker end of our tandem. Our computers were always in sync until this year. Now it's 10% higher than my Captains computer. I can't find our instruction manual . Is it on line anywhere? The wheel is 26 x 1.25. can someone send me the basic instruction on how to re-set the calibration? Thanks. -- Irwin Prince -- can e-mail direct to [email protected]
