I purchased recently this week a Holdsworth 531 Special and I intend to restore it to its former glory. I am not 100% sure of it's production year but it is currently fitted with Huret rear derailleur and shifters, Zeus crank and Suntour rear cassette. On the frame it states that it was a Holdsworth Campagnolo set so I am assuming it was originally fitted largely through out with Campagnolo components and I want to get them back on the bike.
I have purchased a Campagnolo nuovo record derailleur, set of down tube shifters and front gear shifter. I wanted to know what rear cassette (5 speed) would usually come combined with a Campagnolo nuovo record group set if that makes sense?? Is it likely that it would genuinely be a Suntour one, or an I right in thinking it is more likely to be a Regina or is it just down to personal preference?? I would like it to be of a chrome/polished finish if possible rather than black.
Any advice or recommendations would be appreciated.
Thanks,
Damon!
The rear dropout spacing is probably 120 mm. You should measure that. If it is 120, you need a 5-speed freewheel to be true to Campy, or an "ultra-6" freewheel with a narrower (7-speed) chain. Both options pretty much eliminate modern silver freewheels like an IRD or a Sunrace. The Campy NR works well with ranges like 13-24, and even better with 13-21 or so. It can be used with gears as big as 26 or 28, but there might be compromises as you set it up.
NOS Regina is probably $$. But there might be a good used one or two that have not been converted into ashtrays by some flea-market craftsperson.
Send a PM to Pastor Bob. He might have the makings of a good 5-speed for you: Regina, Maillard, Atom, or SunTour.
