I've spotted a decent looking 1980s bike for sale with a 531 frame. The price seems reasonable, but the trouble is that the pedals and cranks are seized
Specifically, this is how the owner describes things:
The pedals are seized onto the crank, I couldn't remove them. But they are still functional as I took them apart and regreased the bearings and axles. They show not a great sign of wear.
The cranks are seized onto the bottom bracket axle, well I couldn't remove them either. But the bottom bracket moves freely and has no play. Also I was able to remove the chainrings to clean and there seem in pretty good condition.
So the bike is perfectly function as it is but issues will arise if you wish to put your own pedals or cranks on. All I can think is when they wear out is to see if a professional mechanic can remove them or it would be a case of cutting threw the bottom bracket axle in order to get at the bottom bracket to remove.
If I were to buy this bike I'd want to sort out this issue asap rather than let things get even worse. I'm not sure whether the owner has already tried using penetrating oil, but if this doesn't work, does this problem sound to you like something my LBS would be able to sort out fairly easily? I know it's difficult to work from a description, but...
Thanks in advance for your advice.
