Yeah, it is a pretty stout tire. I put them on my Salsa Casseroll, which supposedly only has clearance for 38s as well but the 43 BG tire measures true at 43mm and fits just fine. So you'll want to measure for sure, they run at 43 pretty solidly. FYI. Good tire though. Gonna be hard to put the Paselas back on in the summertime! I really like the RNR tires.
