Code: RD5800-Black
Shimano 105 -5800 11speed rear derailleur, GS, for low gear 28-32T black. Featuring a new spring mechanism and cable pitch. Cage length options: SS and GS

 

The Shimano 5800 has gone 11 Speed for the latest incarnation of the 105. The 5800 has been inspired by the innovations of the more upper end Shimano Ultegra and Dura Ace; you can see the technological influences across the design of the 5800 components.  More advanced and lighter than its predecessors and with a more eye catching design, the 5800 promises high performance and is one of the latest cycling must haves.

  • 11-speed 105 wide link rear derailleur

  • Super light shift action

  • Average weight 232 grams (GS)
Mr canillo good shifting
Mr Cullinan 105 lives up to reputation
Mr Matute always loved the shifting from the 105 group without breaking the bank.
Mr Hendricks An excellent product. Fitted and worked like it should have and very impressed with it.
Mr Oliver Great to find this replacement derailleur for my road bike. Have over 25000km on original one.
Andy_Vibes Fast, easy shifts. A few grams heavier than Ultegra but functionally I couldn't tell the difference between this and my Ultegra 6800 setup.
Mr Taylor Bought this one to replace the one on my bike that I damaged in a spill. Went on quickly and worked great right out the box.
Mr Shaw Great piece of kit at a great price, smooth as silk
Mr Lightwood Derailleur needed to work with 11-32 setup, easy to install and tune up. Works like a dream. Delivery fast and all round good experience.
Mr Veitch Great mechanism that is smooth and easy to set up. Instructions are not very good, but found fitting instructions on line.
Mr harrop-Peel Great stuff work a treat , fitted as a replacement for worn 105 kit, added the shifters and all went on my old Jalopy- now running like a dream!
Slava Great product. Shimano 105 series are solid. Merlin cycles is my #1 choice for bike parts.
Mr Smith Great mech. offers clean, crisp shifting. Very easy to install just set the limits and fix the cable so that it is tight
Reyes Switched my cassette from a 11-28 to 11-32 and so I also bought the long cage derailleur. It worked perfectly. Shimano never seems to disappoint.
Menzies What can you say it's Shimano 105 - works flawlessly, and lasts as long as the bike will!
David Previous one did a lot of mileage with little maintenance. At the price I decided to just buy a new one rather than fiddle around with new jockey wheels etc. Shifting so crisp
Hans A bit heavy, but I don't mind. Great bang for your bucks.
Diesel Sharp and smooth shifting
Mr Valle Super sleek design and easy to adjust and tune.
Doherty Provided that you don't have a major spill, will last a lifetime.
Mr Daly I upgraded to the 105 5800 11speed set from my Tiagra 10 speed set and what a huge difference. Shifting is extremely smooth and fast, and the routing of the cable in the bar tape is much cleaner.
Mr Canada Great upgrade from Sora, very smooth shifting.
Mr sanchez Very smooth shifting. It's a bit heavier than the ultegra equivalent. My next build will have ultegra shifters and rear derailleur. Everything else will be 105
