I've run into a tire-size problem with this Raleigh Sports build I'm working on.
I thought I measured things adequately, and thought I could put tires as large as 700x42, but I guess I'm mistaken. Clearance isn't an issue on the back, just the front fork, and it's a matter of tire height rather than width. The Continental Eco Contact tires I'm working with just lightly rub against the top of the fork...strangely, the 700x38 Schwalbe Marathons that I was originally going to mount are narrower, but significantly taller, and they're pressed pretty firmly against the fork. Fenders aren't an issue, I won't be using them.
My question is, how big of a tire can I go with, when there appears to be a lot of variation between brands and models? What are everyone else with a Sports and 700c rims using? Are there other considerations I need to be thinking about?
