They're Mavic MA40s laced 4-cross to Suntour Superbe Pros, that would be some pothole...

The clearance is about 1mm.

The bike feels nice and stiff, made from Reynolds 731 oversize (says Race Only) with a 531 fork. The stays are pretty thin but I've never felt them flex, and I like to climb hills. I LOVE the way it rides, on the track and on the street, but I try to avoid commuting on it because, the less pothole exposure the better
