As of 7/7/21 I'm out of all of the cogs listed below.

A - 26 t Aftermarket cogs from Holland 1/8" chain only, $27.00 Each
(Price refects the economics of small scale production & gray market vs. wholesale purchasing.)

B - 24t, Fichtel and Sachs (Germany) 1 /8" or  3/32" chain.   $27 Each
Long out of production. I have only 2 left and this is my favorite cog. So if you want one you're gonna pay for it.

A good choice for 28" wheels if a 22t work well for you on 26" wheels. Clears DL-1 "Hockey Stick" chainguards.
Will also fit into most fully enclosed chainguards, but I hear it's a VERY difficult installation.

C - 21, 22 & 23t, Shimano, 1/8" or  3/32" chain.  Chrome plated $12 each
Chrome plated. Looks great with a nickel plated chain, on a bike with a lot of chrome.

D - 22t Sturmey Archer (Taiwan) 1/8" chain only,  Chrome plated $8
Sturmey Archer is no longer making black cogs, but I have a few black 18s
Chrome plated looks great with a nickel plated SRAM or KMC chain, on a bike with a lot of chrome.
                       I also have some smaller SA 1/8" cogs, New Old Stock, Made in England.

I also have a few smaller Sturmey cogs.

E -
24t Sturmey Archer (Taiwan) 1/8" chain only,  Chrome plated $20
22t and smaller I can buy wholesale. 24s are a special order from Taiwan.

Going to a larger cog often means needing a longer chain.  I carry a few 1/8" chains.
SRAM Nickel Plated $12 - SRAM Brown $10
KMC Nickel Plated $9 - KMC Brown $7

Cogs made from 3/32" steel are stamped in such a way that they take up
1/8" of space on the driver.  So all such cogs are interchangable.
