Sigma BC Wired Computer
Simple 1 button operation and 8 essential functions makes the BC 8.12 an ideal fit for any handlebar. Features include current speed, trip distance, and maximum and average speeds.
I'm happy with this computer so far. I've had it for a couple of weeks on my road bike, and I've ridden about 80 miles so far with it. It's easy to install and set up. I got caught in some rain on one ride, and it kept on ticking. Decent price as well. It is a little hard to adjust the position once you have it set on the bar, but that's my only (minor) gripe.
