The Knowledge / Re: Removing rounded off / seized hex bolts...
« Last post by Sergeant Pluck on Today at 10:01:52 pm »OK. Given that the stem have 5 rounded off hex bolts; I took the decision to hacksaw it off - bi-metal 24 tpi blade made short work.
That’s what I would have done, as I wouldn’t trust that fork given the demonstrated lack of mechanical sympathy, so would sacrifice it.
The chainstay bridge should be doable somehow, then all that remains to worry about is the rear caliper, the bolts of which the former owner has hopefully never touched, and the mudguard stay bolts. No bottle cages mounted so hopefully those bolts have been left alone two.
Then you will have a lovely frame for not much outlay.
