Listers,
I've been looking at buying a used Stronglight 93 crank set for my Allegro build (or for a potential Peugeot PX-10LE if I take a trip down memory lane) and have been wondering how to evaluate and/or treat corrosion on the cranks. How much corrosion or pitting is too much for safety? For successful polishing or re-anodizing?
SL 93s often show up on ebay in varying condition, but my cash is limited, so auctions like this are attractive initially:
130378915252
The recent thread on polishing prompts me to ask whether it is possible and/or practical to refinish (re-anodize) a crank set like this, and how many irregularities and/or how much corrosion can be tolerated or dealt with in such a process, if it is possible at all.
What are my options with used Stronglight 93 cranks?
Regards,
