I've got some 25mm Vittoria something or others on a halo aerotrack rear rim and mavic open pro front. Clearance is spot on for 25mm. 28mm would be too much as the wheel is pretty much as far back in the track dropout as it can go and a bigger tyre would rub against the area of the guard directly under the brake bridge. Would recommend grabbing some better grub screws for the stay clip things as the ones they come with start to rust up. Otherwise, welllllllllll happy with them!
