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 **Q: is this for 10 speed ?** A: 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. **Q: El de tamaño M es el conocido como patilla larga ?** A: Sí, es lo mismo que pata larga. **Q: What length of chain do I need with a medium cage?** A: 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.
