So, I’ve renovated a couple of classic style 80s road bikes ( a 1981 Gitane Tricolore and a 1986 Jan Janssen “Tour de France”) both of which didn’t really need any major work doing to them. More cosmetics than anything else. Now I’ve moved on to a couple of “proper” bike builds from scratch. Hence, this is why I’ve navigated to this forum for some stirling advice.
First up, is an old early 70s George W Stratton built Claud Butler tourer. I bought it as a project as it was in need of a lot of attention. The frame itself is sound (Reynolds 531) and it came with plenty of original fittings: Gerry Burgess quil and bars, Weinmann brake set and simplex sx410 derailleur and Maillard hubs and freewheel. I had to lose the BB as it was worn and the plastic was damaged.
Now here comes my “issue” that I need some advice on. I replaced the BB with a Shimano 68/118 1.37x24T . It fits nicely, however, it wouldn’t take the original suntour crankset as the inner ring was rubbing out on the chain stay. I guess it’ll be something to do with ISO vs JIS. So I changed it for a Shimano 600 arabesque crankset that seems to fit well. I hung the rear derailleur after servicing it, but it seems that the chain line is wildly out of alignment. Can any of you guys offer some advice on the best approach to setting this correctly? Should I use a BB spacer or adjust the hang on the rear derailleur? I’ll upload some pics when I get the chance.
Thanks in advance.
I’ll follow up with another question a bit later on about best way to treat an acid dipped and stripped 531 steel frame before spray painting.
