Groupset now in stock:
The Shimano Ultegra 6800 11 speed groupset is the successor to the ever popular Shimano Ultegra 6700 10 speed groupset. There's a lot more to the new groupset that an extra sprocket on the rear cassette. Featuring many of the peformance features of the Dura Ace 9000 groupset the 6800 makes it more accessable to enjoy all of Shimanos latest inovations.
The new Ultegra 6800 groupsets features a redesigned 4 arm chainset that allows 34/50 and 39/53 rings combinations to be used on the same spider, we will also see the 36/52 ratio as seen on the Dura Ace chainset. The brake calipers are symmetrical dual pivot design again brought over from the 900 Dura Ace groupset, 10% more powerful than the 6700 caliper.
The rear derailleur has a GS model to allow it to be used with the 6800 11 speed 11-32 cassette, when used with the compact chainset it gives a gear for every ride and every rider, ideal for the toughest sportives.
All in all the new Shimano Ultegra 6800 groupset offers greater performance than the 6700 groupset with the added advantage of lower weight and the extra flexibility of a 2 x 11 speed drivetrain.
With the groupset you will need a pair of 11 speed compatable wheels, you have the choice of any of the Dura Ace 9000 wheels or the new Ultegra 6800 wheels. There are also the new RS81 C24 or C50 models and a choice of training wheels like the RS61, RS31, RS21 and RS11.
I had a half set of 105 before that came with the complete bike and now upgrade to 6800. The breaking is really strong, I slide couple of times during the ride. LOVE IT!
The crank is the biggest difference than the previous one. It feels stronger, stiffer and lighter. The power that you put on the pedal can totally reflect from the back wheels.
Gonna start accumulate some mileage now!
Excellent groupset. Shifts incredibly well both at the front and the back. I have 105 on another bike and the tactile click on these shifters is much more positive.
The brakes are strong and offer plenty of stopping power both in the dry and the wet. Ergonomics are also better. The lever shape just fits in your hand properly when in the hoods, meaning you can still get plenty of power into the brakes when you need to without swapping into the drops. A smaller touch is that with carbon levers they don't get so cold in the winter!
I haven't had chance to test the 11-28 gear range but look forward to being able to maintain a high cadence even on steeper climbs.
Installed on bike and rode 50 miles yesterday. Everthing worked as advertised. My old groupset was shimano 7800, the 6800 is a big improvement. The new 52/36 crankset is just amazing. Went up hills using the same rear gear and cadence as with my old compact crank - but a lot faster with similar power (heart rate).
I have just built up my Pinarello Dogma frame with this groupset and it really flies. The frame is not particularly light, yet the bike clocks in at bang on 8kg (with Mavic Ksyrium wheels) due to the lightness of the components.
The shifting is quick and the braking super responsive. A definate improvement on the 6700 series which I was using on my other bike.
My only gripe would be that I really struggled to get the correct tension in the front mech and set it up so it didn't rub across any of the 11 gears. But then that is probably more to do with me than the equipment!
For this price, unbeatable value.
Just upgraded from older Ultegra 9 Speed to the Ultegra 11 Speed 6800 Groupset. I chose a 52/36 crankset with 11-32 cassette. I've only been on a few rides since the groupset was installed since winter snows have come to Colorado again. First impressions of the Ultegra 6800:
unbelievably smooth shifting through a huge range of gears!! The newer brakes have a lot more stopping power, as well. New black cable housings spiffed up the appearance of an older Specialized S -Works M4. All in all, an awesome groupset at the lowest price on the planet!
Excellent update on a fantastic groupset. The new 11-speed groupset is lighter, slicker and more responsive than ever.
Definite improvement over the 6700 Ultegra groupset I`ve up graded from. Was initially concerned that a switch to under bar cable routing would affect shifting but if anything its lighter and crisper. New brake caliper design also impressively powerful with good modulation. I also like the fact that the chainsets are all now the same BCD so I only have to change the rings for the annual pilgrimage to the Pyrenees. Although with 11 cogs out back, the gears are there to tackle most stuff.
I finally, as my cycling buddies have great joy in pointing out, upgraded my old Ultegra 6510 and joined the modern world.
Instantly noticing the difference in Crank Stiffness (I was using FSA slk crank), shifting response and comfort of the new shaped STI's in the hand. However for my mind the most impressive thing about the 6800 groupset is the beautifully tactile but yet powerful braking generated from the "Dual-pivot" calipers - fantastic.
Would recommend this Groupset to anyone without hesitation!
Completely happy with the results. I used Shimano 2800... Super beginners and now I am riding 100 miles no problem. I could have never survived. I am able to spring to 28 mph in a quick time with no problem whatsoever.
I truly recommend this product to anyone that is considering it for the price.
I purchased this groupset for my latest build which has a Titanium frame. It is superb and with respect I wouldn't of expected anything else from Shimano. I have the grey version which suits the Titanium frame to a tee. Shimano once again with the greatest of respect in my opinion prove they are number one with regard to innovation & quality. Thank you.
I upgraded to the full 6800 groupset with D-A C24 wheels from the 3 year old 105 groupset which came with the bike when new. I ummed and ahhed for months about whether to splash out on a new bike so I could get Di2 but with hindsight I'm pleased my tiny sensible side won over. The improvements in smoothness of gear change, sharpness of brakes and weight are all significant. Best of all are the levers - the higher pivot point makes for ludicrously easy braking when sitting up and a quick prod leads to a smooth gear change every time. So the Di2 upgrade can wait another 2-3 years because I'm very happy with my mech upgrade! Nothing negative to say except I've heard amazing things about Di2...hence not the full 5 stars. I'll save that for 2 years time!
Feels like Dura-Ace but at half the price. Very satisfied so far.
Smoothest shift of any groupset bar none. Ultra quiet. Much reduced effort on front up shift. Brake power improved. GREAT buy.
Used to build up, an Enigma Excell frameset two weeks ago, excellent groupset, ultra smooth shifting and braking, noticeable upgrade over 105.
Beautiful, works better than my Dura Ace 7900 set up on my other bike. Front derailier is so smooth you'd think it was Di2
Ultgegra groupsets are worth every penny you pay for them! I figured i spend a little more for the 11 speed 6800 as I already had 11 speed Mavic wheels to go with it.
So, I've built my bike, still waiting for some final little bits to come so that I can finally finish it, but I took it for a quick spin round the block to get feel for it last night. The Ultegra groupset is a massive improvement over my current 105 groupset on my commuting road bike, silky smooth shifting, hard braking and looks a lot better too. What I really liked when I was putting it together, was the accuracy of adjustment of the various parts. Slight turns of a screw are all that is needed to get the correct position of the brakes, or derailleurs.
Overall I'm more than satisfied with this groupset, and looking forward to fully finishing my bike and riding it.
Used this groupset on a new build, my previous bike had Ultegra 6600. Very pleased with look and feel of this set. Also lighter than expected now installed on the bike. Easy to set-up, you can find the Shimano dealer installation instructions on the web. Smooth, easy gear changes and excellent braking. New lever hoods are also very comfortable. Overall I am very happy with this purchase. Highly recommended. PS. Did I mention it looks great!
Brilliant price for the best groupset I've ever ridden. Clean crisp shifting with no obvious "gaps" in the cassette. Run the 11-32 and its like you have a triple, lowest gear without a weight penalty. Brakes are noticeably better than 6700 and the whole set is a lot lighter too. Not a negative word to say!
I replaced my old shimano 5700 with Ultegra 6800 and WOW the difference the weight is 220 grams less then Ultegra 6700. The shifters, derailleurs are same as the DURA ACE 9000. The shifting is the best I have ever experienced. If you are choosing between 6700 and 6800 DO NOT hesitate to to buy Ultegra 6800. You will love it.
Really nice product, just done a 100mile sportive with this kit and it behaved perfectly. Was a bit of a pain to set up the front derailleur; the instructions (which had to be downloaded from Shimano and weren't provided with the boxes) could have been clearer otherwise it would have been 5 stars.
