The frame has another lug on the seat tube on mine, looks like it's routed right to me. It's hard to imagine that they've put it there for no reason and the Canti setup seems to work as intended@Plankosaurus there's still to much crap stuffed into my shed to get the bike out but I managed to get the phone near the bike to get this pic. It looks weird as the bike was standing on its back wheel but I've rotated the pic to make it closer to yours. You've got the front derailleur and rear brake cables bass ackwards. These frames were made for V brakes so you'll need one of the stops that @Dales Cannon has posted to run canti's successfully, otherwise fingers crossed the braze on wasn't a Friday arvo job

I could route it like that though I guess I think the derailleur cable might rub the seatstay a bit, but shouldn't get a massive amount of use so probably not an issue. Could maybe use a little bit of cable inner through that spring too maybe.
