Is the "medium" cage the ss or the gs version? shimano literature does not use the terms "short" or "medium" in their descriptions of the rd 8000.

medium is GS, short is SS for Shimano RD-8000 derailleurs. They cover 11-28T to 11-34T and 11-25T to 11-28T, respectively. See https://bike.shimano.com/en-EU/product/component/ultegra-r8000.html

is this for 10 speed ?

Actually, this will work with 10sp Tiagra. If you have ST-4700 levers (not sure about the MTB (flat bar) shifter version), then the pull ratio will work for and as 10sp on your 10sp cassette and shifter. You'll be future-proofed when you decide to switch out the lever, chain and cassette for actual 11sp. I am running ST-4700, RD-R8000GS, CS-MT771-10, CN-6701 (10sp) chain and everything works flawlessly.

El de tamaño M es el conocido como patilla larga ?

Sí, es lo mismo que pata larga.

What length of chain do I need with a medium cage?

Hi, we sell standard length: 116 link & you buy it & you have to cut yourself. if you need chain, we have it at my amazon store cycle4less asin #B00KQK5RAW. Bob
