## Description

Thanks to the Shimano Tilt by filtration technology, you can get Dura-Ace functionality. While you don't mind the slight difference in weight, you can rely on Ultegra for changes as clean, smooth, and precise as the ones Dura-Ace offers. For 2017, Shimano uses its shadow design for a thinner mounting design and offers a more agile, integrated adjustment. The pulley keeps a constant distance with the band for more stability of the change. or and it fits bands up to 11-30T. Features: stable performance Shimano Shadow gear with low profile rear design. Uses a 11-30T tape.

## Questions & Answers

**Q: 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.**
A: 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

**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. Bob
