Designed for compatibility with Ultegra R8000 and Dura-Ace R9100 groupsets, it supports a wide cassette range (11-30t to 11-34t), delivering smooth, reliable shifting for serious cyclists seeking professional-grade drivetrain efficiency. ## Description Shimano has used Shadow technology for years on its mountain bike rear derailleurs. It allows for a lower profile and places the derailleur further inboard, keeping them out of harm's way and allowing a better chain path off the top jockey wheel in relation to the cassette. Shimano's R9100 group is the first time we saw this technology carried over to the road side, and we're happy to see its inclusion on the Ultegra RD-R8000 rear derailleur. The RD-8000 is the crowning jewel on the new Ultegra group, and if you are building up or updating a bike, you really can't do wrong with this group. The additional range afforded by the longer cage opens up the Ultegra group to adventure bikes and brings the precision, durability, and value to the masses. Additionally, if you just want to add a wider range to your Dura-Ace steed, adding the long cage Ultegra derailleur and cassette is all you need to spin perfect circles up long mountain passes. The shifting is impeccable, the durability is immaculate and the performance gap to Dura-Ace is about a tire width's margin in a bunch sprint. The change to an aluminum cage and some other minor hardware details are all that separate the Ultegra R8000 version from the Dura-Ace 9100 unit. Two cage lengths are available with cassette ranges from 11-30t (short) and 11-34t (long). Given a few design tweaks, the R8000 rear derailleur works best when paired with R8000 or R9100 levers, and it's a perfect addition to a full Ultegra bike or those running Dura Ace who want to run a bigger cassette. Another advantage of the Shadow design is the more linear path of the derailleur when shifting, which allowed the engineers at Shimano to create a shifter with a shorter throw resulting in more precise and quicker shifts—even with the larger cassette ranges we're beginning ride on everything from tarmac to gravel. We are happy to see Shimano continuing with a barrel adjuster at the derailleur. Road shifters don't have adjusters at the levers lik... ## Features - Material: alloy - Capacity: [short] 35t, [long] 39t - Cassette Range: [short] 11-30 t, [long] 11-34 t - Gearing: double - Compatibility: Shimano Ultegra R8000, Shimano Dura-Ace R9100 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072MPXWL5 | | Best Sellers Rank | #72,215 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #25 in Rear Bike Derailleurs | | Brand | SHIMANO | | Brand Name | SHIMANO | | Case Material Type | Alloy | | Color | Gray | | Customer Reviews | 4.7 out of 5 stars 769 Reviews | | Included Components | Rear Derailleur | | Item Dimensions L x W x H | 9"L x 6"W x 3"H | | Item Highlight | R8000-GS 11-Speed Rear Derailleur | Medium Cage, Black | | Item Weight | 11.2 ounces | | League | Ultegra R8000 | | League Name | Ultegra R8000 | | Manufacturer | Shimano | | Manufacturer Part Number | IRDR8000GS | | Material | Multi | | Material Type | Multi | | Model Number | Shimano | | Mount Type | Braze-On Mount | | Mounting Type | Braze-On Mount | | Number of Items | 1 | | Number of Teeth | 30 | | UPC | 689228623163 | | Unit Count | 1 Count | | Warranty Description | Limited Warranty | ## Product Details - **Brand:** SHIMANO - **Color:** Gray - **Item Weight:** 11.2 ounces - **League:** Ultegra R8000 - **Material:** Multi ## Images ![Ultegra R8000 Rear Derailleur Box - Image 1](https://m.media-amazon.com/images/I/519j7FgjXGL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - SHIMANO Ultegra Rd-R8000 Rear Derailleur - Shimano Ultegra/XT CN-HG701 11-Speed Chain W/Quick Liink - SHIMANO Unisex 305751220 Ultegra Cassette R8000 11V 11 V, Silber, One Size EU --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/47338845-ultegra-r8000-rear-derailleur-box](https://www.desertcart.ph/products/47338845-ultegra-r8000-rear-derailleur-box) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-11-11*
