Schwinn 17-Function Bike Computer

I've owned two of these and ridden in all 4 seasons, driving rain, blinding snow, and even the occasional sunny, warm day. I've never had a problem with either, and find them very easy to set up and calibrate, easy to use, and totally accurate, dependable and reliable.
