Just bought an Orbit America f&f: 531c and nicely built. -
It's all a bit tongue in cheek, but there is usually more than a little sense at the heart of the Velominati rules.

...the lotus looks funny. you should ask the seller how much it weighs.
Out of curiosity I sent the following message:
"More information please:- what is the groupset?
- who built it and for which museum?
- what does it weigh?
- what is the provenance?"
And got this reply:
"not a groupset
came from small museum in suffolk which closed down
weight about 22lbs or 10kg
provenance unknown"I can't decide if he's thick or cagey...
- what is the groupset?

Which seatpost did you use? Is a 24mm one with micro-metric adjust? Where can I find one of those?
Cheers
They go for good money when they ,very rarely, crop up on eBay.Magic Bike Mike is your best bet: either one of his custom made posts or a shim for 22.2mm posts.

Thanks guys. Even on the middle chainring? I was under the impression cross chaining only applies to the inner and outer chainring on a tripple FD
No, the available chain ring/sprocket combinations are dependent on two things: chainline and chainrub.Chainline refers to having such extreme combinations (big/big or small/small) that the chain runs at an angle that causes excessive wear of itself and the cassette and chain ring.
The wider the cassette the greater the problem: a 1x5 set-up will happily run all options.
Chainrub is more apparent when using the smaller rings, because the bigger rings overlap them: you might get rub in the two highest gears and the small ring, but none from the lowest and the big ring (but chainline could then be the issue).
With a triple, I would set it up so that the available gears are evenly in the centre, ie lose one gear from either end.

1 of 4! shite!
cheers rive gauche
so are these still available new?
You know you need an Italian BB, so that narrows it down to two: pre-'78 is 113mm and post-'78 is 115.5mm.
Which one you need is dependent on the front derailleur: post-'78 the derailleur was wider, hence the wider BB.
These do crop up on eBay quite regularly (there are a couple on there at the moment), failing which 115.5mm is the current triple BB so they are available as cassettes.
I'm not sure that 113mm has been used for other groupsets, so I don't know what alternatives are available

The shifter for the front derailleur is, but the shifter for the rear is 9 speed indexed without a friction option (you can get different wheels to change the number of gears it is indexed for).
I suppose you could remove the springs which engage the toothed wheel.
How many gears do you want it to work with, or do specifically want friction?
-
Assuming the wheels are original, you can date it quite accurately: Maillard hubs use a plain date code.
There will be two pairs of numbers: the first two are the week of manufacture and the second, the year.
You'd do well to get £100 for it and there are enough in circulation that no-one will pay to ship it here I'm afraid.
