have you given any thought to internal frame corrosion?

I have given it some thought. I have the bottom bracket out and can see into the seatpost tube. I am guessing that the worst of the corrosion would be in these areas, thankfully it isn’t a steel frame so won’t rot like that. The areas I can see into seem sound.

What about the BB-threads? Anything left?

edit: Oh, you already wrote about it. So the threads are gone. Time for a repair-type treadless BB then.

That is quite job you do there. Hats off, Sir.

I managed to bag a few parts. eBay was able to supply a correct front and rear mech. M550 shimano LX 3x7 as it should be. The front mech being a bottom pull fitting a 31.8 down tube.

Sourced a set of cranks,again M550 LX components. The rings may not be correct but they could be moved on to help with the costs. I still have original correct teeth chainrings.

Was this project finished or abandoned?
