I think I will have the same problem if I try to go to 25mm tyres. It looks like the underneath of the front brake will stop the guard from being pushed up enough.
It’s possible but they need modifying. That means removing stock hardware and going all out with a drill and some files. See mine upthread. Running 25s with pdw slim. Campag calipers being the bottleneck.
