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. -- dabac

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 -- dabac

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. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971

Oh, the horror. 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 -- dabac

Oh, the horror. 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
