OK, I'm not a techie. I read the information, but it just doesn't seem to sink into my brain. I think a new bike requires a new Garmin cyclocomputer. Right? I've looked and looked, but can't find the answer to this burning question.

If I get one, I want to use it for both my bikes. I know I need a second bike mount and sensors, but I'm stuck on the calibration. Does this thing calibrate wheel size automatically or do you have to program in the wheel size? Or do you even need a wheel size? My bikes have different size wheels. Will this be a problem? Is it even possible to change back and forth between bikes? Help!

My friend just got one and had it on her bike for last nights ride. It was sooo coool! bikerHen
