Surface, which you've mentioned is one consideration. Speed and weight (both yours and gear) are the others.
And here's the somewhat boring truth: unless you are extreme in weight or speed, or a bicycle connoisseur (and in which case you wouldn't be asking on a list-serve in the first place) any Riv will do admirably. When it comes down to it, feel free to pick based on color, just don't tell any of the folks here that. :-) The irony is kind of funny that some folks mock cyclists that think they need just the right foot gear or what-have-you, and yet split hairs on frames and handlebars all the same. Not saying there's not a difference among frames or handlebars, but sometimes us systemizer- maximizer types can get carried away.
