record sprint refurbishment continues

Quoted message said:

So ...

a few months ago, starting with an '86 Record Sprint all-original parts
and zero knowledge apart from fixing a puncture, I now have on the
bike:

- Pete Biggs's special (minus shifters) Campagnolo Mirage Ergo levers

- 2nd hand Campagnolo Veloce brakes

- 'new' old-stock Suntour down-shifters for those friction changes

- a cold-set frame from 126mm to 130mm

- (ready to put on) a newly built wheel by me on the excellent
Cambridge course advertised on uk.rec.cycling recently (36x3 Mavic Open
Pro, Shimano Ultegra hub, DT Competition spokes - bit OTT for this bike
but I'm getting a new frame currently favouring MSteel Cycles hopefully
Spring 2005 so I'll transfer it over)

But now what ...

Obviously, I need to get a new chain once I've chosen my cassette
(SRAM/Shimano not sure but this newsgroup might not be the right place
for that discussion) but ...

In a previous set of postings, I get the feeling that the derailleur
capacity is OK for my little upgrade so that can be left alone.

I had a new bottom bracket put on before I realised the implications of
changing from 6 speed to 8/9 speed and chain line. Not much preparation
there!

Also, now I examine properly, the chainrings (52-42) are bloody awful.
Some of the teeth look they've been in a brawl and are half missing! My
'cassette' is 14-24. It's a really pedestrian setup compared to modern
road bikes! I'm nearly always in 42x16 on flat roads but I'm so unfit
the 42x24 is not easy on even those little inclines in Richmond Park!

I check Sheldon Brown's website
http://www.sheldonbrown.com/gloss_bo-z.html#bcd about cranks in order
to investigate new chain ring possibilities whilst keeping to the
existing bottom bracket and crank.

I measured the spider's C-C to be ~65mm so BCD is 110mm perhaps:
"Touring double, standard triple outer". Hmmm, anyone else have a
similar old bike with cranks to verify this? I think it's right though.

Oh well, modern, double chainwheel sets seem to use 130mm.

Any advice? Any spares to throw my way? It seems like I need to search
for 2nd hand or old parts for new chainrings. Or should I just get an
all-new chainset? What would be the best idea?

Cheers!

One can get 110mm BCD chain rings from Spa Cycles. They sell all kinds
of Stronglight rings of this dimension. Some are more expensive than
others , I got a 38T for £14 I think it was. My 1986 Raleigh Royal came
with a Sugino GT double chainset with 110mm BCD rings. I have recently
(thats a relative term) fitted a 1986 Deore triple with 110/86BCD
drilling, I re-used my original 50 tooth ring. If you really want to
keep the chainset, and I would as I like old bikes, just get new rings.
You should be able to measure with a ruler, if it looks like it might
be 110 it will be. The modern trendy term is Compact Chainsets, as if
the you fellows had just discovered such devices.

Definitely looks like 110 BCD. as the 2 sizes either side come up as 55mm or
72mm centre to centre (I have a spare chainring which has a list of the
various measurements on the packaging in front of me as I type). Stronglight
rings should be fine for this bike. as regards suppliers you may find Settle
Cycles cheaper as they do free postage, spa only do free once you've spent
more than £50

Depends what sort of gearing you want. There's only 2 models of SRAM
'road' cassettes (the R9 for Shimano 9sp., and the R8 for Shimano 8sp.
users), and they are quite high spec and therefore higher price,
whereas Shimano offer 8 and 9 sp. models for those on a budget as well
as the top-end stuff. I think the picture may be slightly different
for wide-ratio MTB/touring-type stuff, with cheaper SRAM kit available
lower down their MTB range. If going for a 'road' cassette, consider
also Miche cassettes; a bit harder to find, but available from
Withington Cycles in Manchester (amongst other shops). Their prices
fall somewhere between the two, and sprockets up to 28T are offered if
you want wider gearing for light touring, etc.

Good point re postage. Spa Cycles makes a nice afternoon ride for me so
I didn't consider it. :-)
