No they arent vertical so its a tyre rethink most likely. Shame as i wanted some gravel use!

Long drop callipers would help. If you bodged a rectangular bracket and mounted it vertically in the existing hole for the calliper fixing bolt, drilled a hole higher up, and attatched the long drop calliper to it.

Long drop calipers will NOT help. They won't move the brake mount higher up in the frame.
All you can do is downsize your tyres and pray you never have the urge to fit mudguards.

Yellow Saddle is right - 28mm tyres would be my shout.
As one who rides bridlepaths on 24mm tyres (while being a bit of a chunky monkey), 28mm should cope fine.
Unlucky with the bars and stem though - I'm guessing one is oversize but not the other?

I think Mr Roadkill was thinking about something like this....
And a longer drop brake?

Yeah, I know. They are called drop bolts. However, they work to convert frames designed for old-fashioned long arm brakes to work with short arm brakes. Not the other way around. The problem is the brake bridge. It remains in place and that's right up against the tyre.
Further, drop bolts are not a great idea. The moment of inertia at, especially the front brake, is far too great to prevent lots of flex, resulting in poor brake performance and squealing.
Sometimes the solution is the one we don't want to accept.

A friend of mine has an Allez Sport with 28mm tyres, I'm not sure what brand, some tyres size slightly larger/smaller but his only has about 2mm clearance from tyre to underside of brake, when the time comes he's reverting back to 25mm because mud collects under the brake and rubs on the tyre.

I flat-barred my Scott Expert last year, initially leaving the tyres, 23c, unchanged. All else changed easily. Later, I put a set of 25c tyres on, and that was as far as it would go. Still not enough comfort for me in that, so it reverts to 2nd bike once the Trek mtb is modified.
