I think I mentioned earlier that the new Conti Grand Prix 25 mm tires where a tiny bit wider than the Mavic 25mm tires that they replaced, and I know this because the new front tire is slightly wider than the front brake pads so I have to push the wheel a bit to get it on and off. Well I shouldn't have been surprised on Saturday when I was getting ready to ride and noticed one of the brake pads had been knocked perpendicular to the way it's supposed to be. It was just a loose screw, and as I was at the start of a metric that was organized by my club, there was a mechanic there helping people with last-minute problems. So he tightened it and made sure it was positioned correctly. Then he adjusted the brakes to widen the brake pads a little. In hindsight, I should have done that myself when I first got the new tires. The brake pads were set pretty narrowly because I prefer them that way -- less pulling on the lever to stop on steep down hills.
