I have one Shimano 8-speed 12-25 cassette, that came free with a nice older wheelset (Mavic rims, Ultegra hubs) that I bought used a few weeks ago. I worried that my 64 year old legs would prefer something like a 28T big cog, but on my lighter carbon fiber bike it turns out I can handle most of our short, steep hillettes with the 39T small chainring and 21 or 25 cog. But I couldn't find a model number on that cassette. It's currently paired with older Ultegra 8-speed RD and MicroShift brifters.

You guys both have the 12-25 "W" cassette. The 13-26 "V" cassette shifts the whole range down a tooth (with a little better progression IMO), but probably not enough if you're wanting a 28.

Hopefully some minor thread-****ting is okay since I don't see a sale happening in this instance, but here's an idea for canklecat : if you start with your 12-25 and buy an 11-28 or 11-32 8-speed cassette (pretty sure HG31/HG41/HG50/HG51 would all work), you could steal the 24 and 28 from the new cassette and replace the 23/25 on the old one for a pretty decent 12-13-15-17-19-21-24-28 progression. The 600 Tricolor RD can absolutely handle a 28T, DA lists a max cog of 26T, but I suspect it could be made to work too.
