Group think appreciated: I've got a road race this weekend and it looks like alot of fun: 9 mile loop with 1 mile section of chushed gravel that ends ~.25 miles from the finish. I'd post a link of the video, but work prevents it.
Anyway, it'll be a total mess...
So, would 25mm tires make much of a difference? I have 23mm gatorskins and I was going to run the pressure a little low, but would I be better off doing the same with 25s?
