I like Sigma computers. Mine are wired. They have large figures on the screen. I also have Cateye and Topeak computers (the Topeak wireless), but they have smaller figures which I have found, at times, to be quite difficult to read.

The Simga computer mounts also are very good. It is almost no trouble to twist the computers out and twist them in again. I think that makes them ideal candidates for running one computer on two bikes. The mounts/sensors are fairly easy to source.

There are three buttons, which go against the idea of reducing ways of water to get in, but the main button is large and easy to press to get through the readings.

And the base level models are quite cheap, which, for me right now, puts them ahead of GPS computers.

I've never bothered with cadence.
