I can recommend any of the Cateye wireless models, for speed and distance they work great and are easy to install and setup. With the included handlebar mount they don't look to out of place on a CV bike IMO. Get the out front mount and you might get a second look or two.

The latest Cateye I picked up I can recommend only with caution. The Padrone Digital wireless that can track distance, speed and cadence. Why do I recommend it with caution? Because it is a pain in the butt to get connected, the instructions leave out information and could use some helpful tips and hints. I had to call Cateye customer service and they talked me through it. To me it was well worth it for the cadence feature.
