32mm mostly-slicks on the cross bike.
Still rode with the faster guys. Hardly felt slowed at all. A tiny bit maybe, but the numbers at the end were hardly significantly different. And, it was fun.
When I put 25s on my S1 I do go significantly slower. Which tells me that even though it looks like there's just enough clearance, there really isn't in real riding circumstances.
