Upgrades/ New Shit in Norwich

Just looking at the clearances in that frame I think brakeless would be the way to go.
Not a lot of flex from the forks and it's going to go quite wrong if the tyre hits the down tube.

Good news as far as this is concerned. Had to grab a fistful/lock up my legs behind a sudden braking Transit on the ride home from work today - as much of an emergency stop as I'd hope I'd ever deal with - and everything was fine, no tyre/frame interference even though there was certainly some 'give'. Seems like my bodging has paid off!
