Campagnolo wheels

Peter: they are probably not original to the bike, but they are contemporary (or maybe even a bit older as they were standard on the 1977 Darmahs. weren't they?).
I do get myself worried about them every once in a while (I've accumulated 2 wheels, one from a 600TL and the other from an Allazurra) which should be a direct fit, but I'm looking for the right colour paint, and I will probably need to get 6-bolt rotors as well.
From what I have been able to tell, it is the Speedline wheels that were really high magnesium content, and corroded very quickly. The Campagnolos were "elektron", and I haven't heard any definitive evidence that they were any more prone to cracking or corrosion than the FPS replacements for the Speedlines....so for now I continue to use them and look carefully for corrosion. If I start to ride the 900 more regularly I'll finish off the other wheels and install them.

Peter,
If you noticed external corrosion, I would be highly concerned that the
damage was also going on internally where you can't see it. The only
way you find out is a) get them x-rayed b) when one of them
disintegrates underneath you (generally at high speeds when loads are
increased). One minute your wheel is there, the next second she's gone!
There were a lot of nasty accidents/fatalities on those wheels
(predominantly Speedlines) in the early 80's.
I would have any mag alloy wheel from that period surveyed / x-rayed
if it were mine. Nice bike though!
