13-21 8 Speed Shimano Cassettes - do they exist?42-52 Kelly

I found an old listing on the net for a 13-21 Dura-Ace 8 speed, now all I can find is 13-23.

Anyone have any leads on Ultegra or Dura Ace 13-21 8 speed?

Thanks in advance.

My guess is you could buy an 18 tooth cog, take the cassette apart, save the 23 tooth cog for your declining years, and put it back together with the 18 in the appropriate spot. New cassettes usually come apart very easily.

You may change cogs out but I believe the Ultegra and DA cassettes have the first four or five big cogs riveted together making it difficult to replace these. The 105 cassettes however use a small allen screw that allows any of the cogs to be replaced.

Mine are pretty old and what looks like a rivet is a tiny hex head bolt that I turn with a needle-nose vice grip.
