Bikes can be so mean - mini vbrake will not fit

[hamster]

Here you go: a seatclamp with a stop for a cable outer for cantis: https://www.tredz.co.uk/.One23-Cyclocross-Seatclamp-With-Canti-Brake-Cable-Stop_45709.htm

Not all mini V's are the same height. My brother upgraded the tyres on his boys bike (24") for fatter tyres as he's starting to get some serious air and we max'd out on frame clearance, but the tyres ended up doing what yours are doing! I have a few pairs of Mini V's and managed to find a pair that had a few extra mm in height to avoid tyre contact, guess they must be midi V's?!*

Hmmm, aren’t those meant for the opposite problem ? The Minis fit my rims perfectly, just the clearance is to small? Or do I just not get what they do?

They'd give you a bit of extra clearance between the cable & tyre as the whole caliper would be shifted upwards

These ones have better dimensions etc so it might be workable: https://amzn.eu/d/2EDOdij

I don't know where the pads are sitting on the calipers currently - if they're near the top then they might work with this... If they're near the bottom you're going to miss the rim & will be breaking on the rubber
