I have a bike with Campy Chorus 11 speed, all parts bought about six years ago if that helps. What is the max tire size I can expect to fit? Frame clearance isn't an issue, the brakes will be the limit. The pads are set at the bottom of their travel, so I have quite a bit of clearance too the arms, it is squeezing in between the pads I am worried about. The rims are HED Belgiums (not +, just plain).

Thanks!
