Bumping this thread instead of making a new one. I’ve been doing researching for my next tri bike with larger tires on these TERRIBLE roads, and the results are very limited. The best I could come up with online is…
Trek Speed Concept (Gen 2) = 28c
Trek Speed Concept (Gen 3) = Possible 30/32c ??
Current Cervelo P5 and P3X = 28c (30mm actual, with 3mm clearance on each side)
jn46, yes the older P5X is different (3mm narrower). You were able to fit 30.5mm actual width on the P3X. The frame’s total clearance is 36mm, which would leave just 2.75mm on each side, provided perfectly centered wheels. I was under the impression you don’t want to push it under 3mm each side. You were comfortable with the 2.75mm clearance?
Found this “100% kind shooting”…

Has anyone found any other options?
