Ok, so LBS wen't over my bike, adjusted cables, wen't through the gears, because I was getting a clicking when I would down shift.ANYWAY...my computer was STILL off jumping all over the place. They said the pick up wasn't aligned right and fixed it (they put it on in the first place.) Anyway, they show it works go out to ride.....and there it goes AGAIN. I finally rode without my heart monitor and now it works fine. Last night at LBS we asked the manager what I can use with the computer (it's a trek computer) and he shrugged his shoulders....I dunno .
So, I'm coming to the pros!! What do ya'll recommend. I'm using just one I got from GNC, I like it because it counts time, calories, obviously h/r and shows precentage you are working at. What do ya'll think?
