You might want to think that you actually, on a clean wet road, assuming decent tires and a good rider, there is more traction there than you think. You really just have to be smoother and a bit slower in the rain. You don't do nothing sudden in the rain, be it steering inputs, braking or acceleration. I have seen good road racers only loose a second or so per lap on a 1.5 mile course in the rain. Slicks are another story.
