Subject: Comprehensive chart of chainwheel sizes?

Hi guys,

I'm toying around with an idea that is probably equally pointless an
entertaining, but to put some reality into it I need to know wha
chainwheel sizes there are available.
Does anybody know of a compiled list somewhere, or do I have to kee
trawling the online catalogs?

(I have tried a quick google, but it didn't lead to anything helpful.

I think the 80-tooth chainrings were a Greenspeed item also. See
http://www.greenspeed.com.au/gsparts.html . Custom chainrings are also
available from Highpath Engineering: http://www.highpath.net/cycles/eggs/01.html
. Available in 11 to 110 teeth!

Once upon a time I read an article in HPV news that described how to
make a custom chainring with a router, a carbide bit, and a plate of
aluminum. I'll try to turn up the article if anyone likes.

Found 'HERE:' (http://www.ihpva.org/Builders/Sprocket/)

Together with the printers I have available I have to rate th
usefulness as "moderate", as the templates that can be printed out ar
very pale. Still, it shows nicely what can be done with few tools and
bit of dedication

You can look for big chainrings here-

Although it is a USA & recumbent-oriented site.

The Vuelta Alloy rings go up to 60T, and there's some RANS and
Greenspeed ones that are 62, 65 & 74T. As I recall they used to sell an
80T, not listed now but they might remember who made it.

Need to know crank application for diameter and your preferred format,
(e.g., the middle of a triple shifts better with ramps/pins). There are
oodles of formats out there, so a 'listing' would be scattershot anyway
considering aftermarket rings and adapter systems.

p.s. for special applications (Hour Record?), custom chainrings.

Long explanation follows:

I've got a set of composite wheels that I'd like to use for all-weathe
commuter in fairly flat terrain(17 miles each direction).
Trouble, and my challenge is that the rear wheel has a S-A 3 spd hub
which is a bit more limited than I like.
Through helpful pointers from posters here I found Sheldon Brown's gea
calculator and a reasonable starting point(front triple 40-44-48), s
now I've spent some time searching for the "ultimate" chainring comb
both to widen the range and to add more intermediate steps *w/
repeating* already available gear ratios.
One option I've looked at is to make it a quad in front (as foun
'here:' (http://abundantadventures.com/quads.html) ) but I thought
could make do w/o their splined carrier and simply bolt it all up.
My theory is that I could use two bolt circle diameters, and use chai
ring bolts for a double to hang the biggest chainring outboard of th
2nd biggest, then use a smaller bolt circle and chainring bolts from
triple to hang the other two rather more traditionally to the inside.
I don't want to use a 36, as the combos I've calculated generate repea
gears, but a 37-40-44-48 would have a slightly more even spacing whe
combined with a S-A 3 spd than a 38-40-44-48 would.

I've thought of trying to force the S-A hub out of the wheel and stic
a Shimano hub compatible with a current body in there, but I'm no
certain if that is possible w/o causing irreparable damage to the wheel

Dear Andrew,

We caught on to your habit of pocketing valve caps long ago!

Do you think that the cycling public is unaware that you recommend the
larger chain ring solely in order to sell the extra chain link?

Cheers,

Carl Fogel

Lists a 37.

Of course you didn't say what bolt circle you needed...

Starting from scratch, or rather, from scrap, I have full flexibilit
in that matter - as long as I can assemble a matching set

MO and Online catalogs do not the bike parts market make. TA rings are
available for just about any bolt circle, 1 tooth increments, road and
track pitch.
