Im trying to build my mate a rad bike. Cue seeing a rad semi lo pro type thing on ebay with ridic tight clearances at rear. Takes 23mm clincher comfortably but would ideally like to put 25mm tyres on it.
Thought of a few options -
- File out the dropout to push the wheel back like in the attached photo. Would this be safe?
- Ask someone to braze 3/4mm to the bottom of the dropout to make the frame sit higher on the wheel.
- Get someone to braze new track dropouts.
I have done many a bodge before with a file so pretty competent.

What's wrong with 23s? I've ridden them most of my life and the worst that has happened is that I got old. If you can feel much difference between 23 and 25 you're a better man than me, which isn't that difficult.
