Not exactly vintage, but I've a nice junior cassette with 15-25 ratios, Ultegra 6600 10 speed, as stated in the title.

15 - 16 - 17 - 18 - 19 - 20 - 21 - 22 - 23 - 25

Used but seems OK, I've tried it on my bike with new chain and it changes gears fine and doesn't skip.

Having said that, it's a used cassette, so you never now. And it comes with a generic (heavy) end "screw".

Expensive new, looking for £40 posted or a reasonable offer.

Thanks.
