Shimano Ultegra RD-6800 Rear Derailleur

Shimano Ultegra 6800 11 Speed Rear Derailleur

Shimano Ultegra 6800 11-Speed is one of the most anticipated road groups of the season. With trickle down from Dura-Ace 9000, what’s not to love? This race inspired group is super fast, reliable, and above all… smooth. The 6800 rear derailleur has been completely overhauled. The Shimano Ultegra 6800 Rear Derailleur is more compact and lightweight. A new spring mechanism has also been added to are balanced and equal across the cassette range.

Wide gear range is available with the use of the GS medium cage derailleur, which accepts up to a 32T rear cog for big climbing days.

  • Super-smooth and crips shifting with wide link design that increases rigidity and reduces shifting deflection
  • Trickle Down technology from Dura-Ace
  • Sealed bearing pulleys
  • GS Cage and SS Cages available to customize your gear ratios
  • Max Cog: SS: 28T, GS: 32T
  • Maximum front difference: SS: 16T, GS: 16T
  • Capacity: SS: 33T, GS: 37T
  • Weight: SS: 195g, GS: 207g
  • Compatible with 11-speed Shimano Road systems only.

Long cage provides 11-32 option to replace a triple.
The long cage allows use of an 11-32 cassette which provides the same low gear ratio as a triple with a 28 tooth cassette. And will still work with an 11-23 cassettes for flatland rides.

Great upgrade
Great performance as would be expected from this derailleur; crisp, accurate shifts. Easy to install with detailed instructions. Great price and fast shipping from Jenson = an awesome deal.

The Usual Shimano High Quality
Needed the mid-cage RD to accommodate Ultegra 6800 11-32 cassette on new Orbea Orca Bronze Ultegra roadbike (Fine!). Easy swap with new chain needed and all works very well.
Needed the 11-32 to help handle some huge 5-8%+)long inclines (e.g., 10+ miles)here in Central Oregon (and a few 12% pulls).

Worth the pruchase
See my review of the 11-32 Ultegra 6800 cassette. I cover this there. You will like the 6800 components. Because it is 11 speed I was able to add a 32 for climbing and not give up any other gears to do so. Yo need the medium cage for the 11-32 cassette. I thought the 11 speed might be finiky to adjust and operate but not the case. solid, smooth and easy to get installed and operational.

Ultegra rear derailleur
Upgraded from 9 spd Durace to 11 spd Ultegra. Was easy to adjust with the 11-32 cassette and has worked well for first two months on the smart trainer.

Ultegra medium size derailler
Got this derailler because online literature stated I needed the bigger derailler to use with 11x32 rear cassette and 50/34 chainrings (previously had 11x28 cassette). Installed rear cassette and new chain easily. Derailler was easy to install but being the first time for me was difficult to adjust. The key is to get the length of the cable just right then fine tune the adjustments. Once I got it adjusted correctly, it worked beautifully. Difficult but not impossible do-it-yourself project requires patience.

Awesome Shifting
Ultegra 6800 is an industry standard. The shifting with this derailleur is butter smooth and very crisp and precise. Great value for the money with a high level of performance over 105 but a better price tag than Dura-Ace. For the enthusiast rider Ultegra is the way to go.

Best value out there.
Ultegra is hands down the best value in road cycling. The shift quality is 100% as good as Dura Ace, at a fraction of the price. Yeah, it's a little heavier, but if you're looking for function and weight isn't the most important thing to you, Ultegra will serve you well. Not that it's heavy, it's totally not, it's just not as feather light as Dura Ace.
