I got caught in my first downpour on my new Cannondale R600 last week and I'm glad to report that the bike didn't shrink <g> and the tires seemed to grip OK on the wet roads (although I wasn't about to push my luck in any hard corners) The worst part was the shoes full of water that took about 3 hours with the blow dryer to get dried out. I'm either going to get a pair of sandles or find something to cover the shoes with. (any suggestions?) Riding in the rain wasn't too bad but I did get questioned by my husband about why the bike was in the den and why I was using the blow dryer on it <g>
