Its direct mount design improves stiffness and gear precision, while compatibility with 11-30T cassettes offers versatility for diverse riding conditions. Crafted from lightweight aluminum, it balances durability with minimal weight, making it a top choice for competitive and passionate cyclists. ## Description Shimano Ultegra RD-R8000-SS 11 Speed Rear Derailleur features direct mount attachment, providing a stiffer derailleur/frame assembly for improved gear shifting while minimizing the risk of frame damage in the event of an accident. The Ultegra R8000 derailleur incorporates Shadow RD technology, which places the derailleur body under the cassette. This is to protect the derailleur in the event of falls or projections, but also to keep it at the same distance from the cassette, regardless of the pinion used. The short cage version allows the installation of cassettes with teeth from 11-25 to 11-30. The long cage version will allow the mounting of teeth from 11-28 to the new 11-34 for the most difficult passes. Mini tooth: 11 teeth. Max teeth short cage: 30 teeth. Max teeth max cage: 34 teeth. Review: Mejor sistema para tensión de cadena Mejor diseño de caja de poleas y de articulaciones. Review: I upgraded from a 2005 10 speed Ultegra to 11 Speed Ultegra. The gear changes are smoother and quality of the newer product is great. Would recommend. ## Features - Stable Shifting Performance - Shimano Shadow Construction - Low profile rear design - Uses up to an 11-30T cassette ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072MKT5NR | | Batteries Included? | No | | Best Sellers Rank | #17,563 in Sporting Goods ( See Top 100 in Sporting Goods ) #8 in Bike Rear Dérailleurs | | Bike Type | Road Racing | | Color | graphite grey | | Customer Reviews | 4.7 4.7 out of 5 stars (718) | | Date First Available | 26 June 2017 | | Department | Unisex | | Global Trade Identification Number | 00689228623156, 04524667623151 | | Height | 9 centimeters | | Included Components | 1 x Shimano Ultegra RD-R8000-SS 11 Speed Rear Derailleur, Black | | Is Discontinued By Manufacturer | No | | Item model number | C8C055 | | Length | 15 centimeters | | Manufacturer | Shimano Inc. | | Material Type | Aluminum | | Number of Items | 1 | | Product Dimensions | 14.61 x 11.43 x 9.53 cm; 198 g | | Season | Fall/Holiday | | Size | Standard | | Sport | Cycling | | UPC | 689228623156 | | Weight | 0.7 Pounds | | Width | 12 centimeters | ## Product Details - **Brand:** SHIMANO - **Colour:** graphite grey - **Item weight:** 198 Grams - **Material:** Aluminum - **Mounting type:** Braze-On Mount ## Images ![SHIMANO Ultegra Rd-R8000 Rear Derailleur - Image 1](https://m.media-amazon.com/images/I/51h5L8rAflL.jpg) ## Available Options This product comes in different **Color, Size** options. ## 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.
