Moving you through 11 gears.

When Shimano decided to revamp its trusted Ultegra groupset under the new 11-speed 6800 banner, it did so only after carefully studying the mechanics of its flagship Dura-Ace 9000 mechanical group. This is represented most clearly with the new 6800 STI Shifters, as they were engineered to mimic both the 11-speed functionality and beautiful aesthetics of its popular older sibling.

If you've spent time with Ultegra's ST-6700 levers, you'll immediately notice the refined hood shape of the new 6800 STI Shifters. They've slimmed down considerably, borrowing the same look and feel of Dura-Ace mechanical, which took its cues from the flagship Di2 levers. It's a welcome trickle-down effect for longtime Ultegra devotees, as the new design lends itself to improved comfort and grip, combined with, most importantly, crisper shifting.

Made from a dual-compound rubber composite, the low-volume hoods are reminiscent of Di2, and the design makes lever accessibility easy. The lever blades also received a sleek redesign. They're still made from carbon fiber but their outward curve and feel is now more pronounced than prior versions, which makes for a more positive interaction from either the hoods or drops. And to accommodate a large range of hand shapes, Shimano included, like Dura-Ace, 10mm of reach adjustment for the levers.

For the shifting itself, Shimano's 'Rider-Tuned' philosophy really makes itself known. This is the title given to Shimano's campaign of providing you the best rider-experience possible. Throughout the entire Ultegra group, every component has been given little custom touches, but the levers have received several. To start, Shimano has shortened the lever stroke. In fact, it's reduced the stroke by around 13% over Ultegra 6700. Obviously, the less distance that you have to push the lever, the faster your shift will move up or down the cassette. And during the act of shifting, the required effort has also been lessened. In tandem with the reduced stroke, the shifting experience has been minimized to light touches that rival both Dura-Ace 9000 and Di2 shifting speed.

Shimano also aimed to make the shifting effort seamless across every sprocket of the cassette. The effort required is now equalized, regardless of whether you're moving across the bottom or top of the cassette. Using what Shimano calls Vivid Index Technology, down-shifting feels just as crisp, engaging, and as smooth as up-shifts. This is due in part to superior mechanics, but in the larger scheme of things, it's more attributable to something as simple as proprietary shift cables. Ultegra 6800 STI levers use Shimano's exclusive polymer-coated shifter cables. We know that it doesn't sound like a big deal, but the new cables play a key role in the near-elimination of mechanical drag, and they also provide a flawless shift performance.

The Shimano Ultegra 6800 11-Speed STI Shifters are available in one color and one size. Please note that these shifters are specifically designed for use with Ultegra 6800 components and Shimano's polymer-coated and PTFE cables.

  • The privateer racers' preferred shift levers
  • Precision actuation with more positive lever feedback
  • Carbon fiber brake lever blades shed grams
  • Compatible with Ultegra 6800 components and PTFE cables
  • It's difficult to overstate the value of Shimano's Ultegra drivetrain

Agree with the other reviews

No complaints at all about these shifters. Running gear and brake cables is easy. I even had a cable snap inside and was able to get it out. There's a screw on top to adjust the reach. They look good and are comfortable on the hands.

As part of the shifting system, they also work very well. With the 105 shifters, the action felt mushy but the Ultegra shifters are crisp and confident. I don't have to manhandle the levers to go from small to big. The indexing is spot-on. Whatever problems I have usually is because I need to replace cables or housing or I put the wrong tension on one of the barrel adjusters. In short, these simply work and are reliable.

Silky smooth with a polyester price

  • Familiarity: I've put it through the wringer

Great value! One step down from the top-of-the-line Dura Ace, but hardly sacrifices any performance. Slightly heavier, but negligible when you consider other weight weenie upgrades you can make.

I have beat the crap out of these things for 3 race seasons. Crit races and road races, the shifting is fast and precise. The audible and mechanical "click" is reassuring and obvious. Shifting mistakes are rare with the Shimano STI shifters, because there are two different levers unlike the SRAM double tap system.

Ergonomically, the hoods are comfy and the levers don't sit far from the handlebars. Important! You spend a lot of time on the hoods. I have smaller hands and never have any issues reaching to brake or shift in the drops.

These shifters really tick all the boxes for value minded customers.
-Extremely Durable
-Shift quickly and precise
-Relatively inexpensive when compared to top-of-the-line shifters

Ultegra 6800 Shifters

  • Familiarity: I've put it through the wringer

The best purchase I have made in the 20 years I've been riding road bikes. I replaced SRAM shifters with Ultegra 6800 and my bike rides so much smoother with easier shifting. Completely regret ever trying SRAM!!

Smooth and reliable.

  • Familiarity: I've put it through the wringer

I've been riding Ultegra shifters for so long, anything else feel unnatural. These are comfortable, smooth, and reliable. The jump when you need an uphill bail-out is very handy!

Awesome upgrade from 105

  • Familiarity: I've put it through the wringer

Recently upgraded my Lynskey R230 from 105-5700 to full Ultegra 6800 and what a difference. 105 is rock solid but the 6800 is so smooth. The longer throw arm on the FD makes front shifts much easier. RD is sure, quick and precise. I run compact up front and for the upgrade changed from 11-25 to 11-28. Went to the long cage derailleur in case I find I need more climbing gears. Well worth the upgrade

Shimano Ultegra 6800 STI Shifters

  • Familiarity: I've used it several times

I'm so happy to have upgraded to these Ultegra 6800 STI shifters. They are so much improved over the previous versions and the guys and Competitive Cyclist helped me all the way. I set set up all the components to match and never looked back! They're great!

Excellent Shifting and Ergonomics

  • Familiarity: I've put it through the wringer

The Ultegra 6800 shifters give you the amazing performance you'd expect from Shimano at a reasonable price. Ergonomics are a vast improvement over the previous generation. Hard to be performance/weight to price ratio.

Crisp and Precise

  • Familiarity: I've put it through the wringer

After many miles, rough and smooth roads in all kinds of weather these shifters are the real deal. Crisp and precise. The respond on a dime. The are a little heavier then the Dura Ace. The action is awesome, no delay.

I have my bike with all Ultegra 6800 components, except for the Shifters, I´m running 105. I don´t feel my gears as crisp and smooth everybody claims for the 6800´s series. Am I missing something here? Do I need the Ultegra shifters for the complete system to work at his best or my 105´s should do the work (in that case my index or tunning must be wrong)? Thanks for any advice or comment.

Smooth shifting

  • Familiarity: I've put it through the wringer

I upgraded from Dura Ace 7900 which I thought was great shifting but Ultegra 6800 is a HUGE improvement. Best word to describe it is smooth. Very light action to shift rear or front derailleur.
Only big adjustment is the trim function. You get 3 clicks to go from big ring to small. First is to "big ring trim", second is to small ring, and third is trim for small ring. This takes a lot of getting used to and is kind of a pain to set up initially. You need an inline cable adjuster to make the Ultegra installation. Once adjusted, it works great!

Ultra Nice Ultegras

  • Familiarity: I've used it several times

This is my first pair of Ultegras so I'm not sure if I know as much as the next person, but in my opinion these STI shifters are awesome. Very smooth shifting every time, and they feel great. Also 11speed is where it's at, might cross your chain a bit more causing more front derailleur adjustments, but the extra gear is well worth it.

Goodbye 6700 10 Speed

  • Familiarity: I've used it several times

I recently upgraded my Roubaix from a mix of Ultegra/DuraAce 10 Speed to all Ultegra 6800 11 Speed. What and evolution. The shifting, in particular, is incredibly refined. I always kept my components clean and replaced cables frequently, so the difference I'm feeling isn't just shiny new components; it's a technology leap. The braking is greatly improved as well and just feels solid and crisp with great feedback from the levers. The smaller hood shape is very comfortable and the looks are appealing. The cable install is also easier than ever. Well done Shimano!

Smooth shifting...

  • Familiarity: I've put it through the wringer

My new Cervelo came equipped with the Ultegra 6800 11-speed drivetrain and is noticably smoother shifting than the old 6700 10-speed. First thing you will notice is the redesigned hoods are smaller and more comfortable. Then you'll notice the shift stroke is shorter and more crisp. Combined with the PTFE cables and 6800 group derailleurs it is a smooth system-rapid shifts with distinct stops. All this and a new sexy shape to the brake levers-good looks and great performance!

i bought the ultegra 6800 shifter and F/R derailler. but I'm using 10s cassette. is this set up will work?

Is the Shimano's polymer-coated and PTFE cables of this goods included?

Shimano cables and housing are included with the 6800 shifters.

Please be advised that both sets of housing (shift/brake) and brake cables are NOT included with the shifters. I was quite surprised when I received my first pair in a ziplock bag and called CC for a replacement. They assured me that all cables and housing would be included (which BTW is the standard in the industry), BUT the replacement set came in a baggie (not official Shimano box), missing the aforementioned items again. After contacting CC again, I was informed that this is the way Shimano ships the items to CC..."incomplete" is all that comes to mind.

I wish I would have read this comment before ordered the shifters. It doesn't clearly say the cables are included so I ended up purchasing cables which I now have to return. Maybe under Tech Specs it can say "Shimano PTFE Shift Cables Included."

Will 6800 shifters work with Dura-Ace 7801...

Will 6800 shifters work with Dura-Ace 7801 rear derailleur?

Unfortunately, these shifters will not work with a Dura-Ace 7801 rear derailleur as it is a 10-speed derailleur and these are 11-speed shifters.

will 6800 shifters work with 6700 group...

will 6800 shifters work with 6700 group set?

No, unfortunately the 6800 shifters will only work with 6800 or 9000. The 6700 is 10 speed and the 6800 is 11 speed.
