My LBS always gets kind of pissy when I ask to look though their junk. Plus, how long is it going to take me to find a 23t and 26t cassette? They're not super common gears.
My other decision is whether to stick with my current 12t cog or go up to a 13t, which I found for $26 online.
Good enough. The cassettes that went up to 30 had a 23 and a 26. I think this is a HG90 or HG70 unit. If you look at the back, you should see the heads of the 3 small pins that hold everything together. Hopefully they are either a tiny hex key head or a hex head. Either way, unwinding these to get at the loose cogs will be a lot easier than grinding away at the riveted pin heads.
12t - you must be referring to the threaded first position cog on your Uniglide cassette. But your hub does not accept a 12t small cog. The smallest cog possible on the 600EX Uniglide was a 13.
Second point: $26? Seriously? If I were to sell of the hundreds of pounds of similar bike gravel crap that I've horded, I should be rich. I guess.
BTW: don't get a Dura-Ace
#1 threaded cog. Smaller diameter. Not compatible with your freehub. Unless you really really have a 12 tooth first cog, which means you likely have an early Dura-Ace freehub.
