I bought an old bike, basically for the frame (Reynolds 453). And after completing at least a months restoration, the bike was put back together, whilst riding the crank bracket came loose and I tried to put it back on without success. I took it to the local bike shop and was informed that the bolts were put on incorrectly, i.e left hand thread put on right hand so and vice-versa. He said that the threads might be knackered on the frame now, and if that is the case then the frame is scrap............
Now you can imagine after putting in all that effort, I'm not best pleased, more so, as the crank was put back together by someone else (trying to help).
My question is this : If the threads are done, is there a way of securing the crank, but NOT screwing into the frame ?
The frame was probably made in the 70's, and is on an old Falcon Team Equipe bike.
Your help would be appreciated.
