RMan64 On time. Shimano quality as expected. Upgrade to WSD Trek 1600 which had a triple. Wife really enjoying the upgrade and components have giving the bike a "new" life!

Matthias Great customisability, great pricepoint for one of the best value groupsets out there. Love that you can choose BB type, derailleur types, brake types, etc.

James I own dura ace 9000 mechanical and now ultegra r8000. I have to say, the performance of r8000 is every bit as good as the dura ace. Asthetics is the only ddistinction. Outstanding product.

Mr Thwaite Upgraded to the Ultegra from my entry level groupset (a mixture of budget 8 speed SRAM and Shimano components). Originally intended on going 105 but seemingly impossible to get hold of at the moment so I spent the extra. Glad I did. Shifting happens so smoothly, brakes are such a significant upgrade. Ergo shifters are a joy and so many cassette options. Bike is significantly lighter also.

Dan M Great value bundle, bought together with a frame set and all fitted together with ease. Super smooth group set, impressive brakes. Very smooth ordering and delivery process from Merlin.

Mr C great groupset, sensible improvements over last iterations. also, very fast delivery to Germany

Mr Cummins Great product, first class shifting and easy of fitting, top class quality

Mr Doughty Absolutely brilliant upgrade. Very easy to fit, excellent quality, and well packed next day delivery from Merlin.

Rudi Very good product, had no problems even with my old Ultegra groupset which I had for over 10 years

D. hunt Have not installed yet. But packaged well and looks nice!

Mr Roberts Great groupset , excellent quality and shifts smoother and quicker than the older 6800

Dave This is the 2nd Ultegra groupset that I have bought from Merlin as the cost was excellent, the product is excellent and all my bikes are now compatible. Cannot fault the groupset....ITS AWESOME and looks great too.

Mr stephenson Superb group set, it took a 1.5 days to instal, but part of that was problems with internal, The instructions are naff, but youtube helped. The big challenge was attaching the rear hanger correctly (google it)once that was worked out it all came together and now the groupset makes the bike feel brand new!

Mr Talbot Great quality as usual. I'm a novice bike builder and even I found it relatively easy to install and set up with a little help from the online dealer manuals and a couple of helpful youtube videos. Good price from Merlin but my only criticism is that it did not come with the correct size bottom bracket tool adaptor and had to buy separately. Not sure if this standard shimano or merlin practice.

DonWA Outstanding! I've owned many previous models of Ultegra but none were as good as this one. Shimano has truly raised the bar so high that it would be hard for any other manufacturer to match the shift quality and beauty of this groupset at this price.

Dave Superb groupset. Works like a dream and great value

AT Fitted this with a 52/36 crankset and 11-34 cassette for an old Shimano 10-speed wheelset. The shifters and derailleurs didn't even blink at the massive range asked of them, and shifting is crisp, quick and satisfyingly positive up and down the block, whether in the big or small chainring. A few gaps in the cassette with that range, inevitably, but easy enough to deal with for the sake of not having to buy a new wheelset as well as the gruppo. As an upgrade from 5600-series 105 and Tektro brakes, this was a revelation. The front derailleur is the stand-out component and switching chainrings is now as easy and effortless as shifting cogs. The brakes have wonderful feel and modulation, once you're used to the massive stopping power. It's a little more finicky to set up and get properly humming than previous Shimano group sets but once it's just right it's flawless. The shifters are lovely and comfortable, and the adjustable range for the brake lever reach is handy. Not sure how much I notice the textured rubber on the hoods through a pair of mitts, though. Definitely worth it at full price. Even more worth it for the deals Merlin offers. And it looks very, very pretty.

Mr Herrod Love this new group and the gearing option. The 52/36 and 11-34 are perfect for the steep hills where I live. I am just coming back from open heart surgery and this combination doesn't leave me in wanting even on an 8% grade. Love it.

Michael Had a 10 speed Campagnolo groupset. I wanted an 11 speed so I could get a 11/32 cassette. I was concerned about leaving Campagnolo but the Ultegra 8000 groupset works great. Extremely smooth shifting.

Tommy Solid Solid groupset. Put about 200 miles on and it feels great and smooth. Keep in mind that the groupset comes with gear and brake cables and that a set is not necessary.

DC Merlin had the best price on the groupset and fast shipment to U.S. Overall, it was easy to install the groupset but rear derailleur took a little extra time to find tune due to difficulty with the barrel adjuster. Significant improvement in shifting compared to Ultegra 6700 10 speed. Very crisp and accurate. The use of 11-30 cassette with short cage derailleur is a big plus in my opinion without having to go with mid/long cage. Very happy with the upgrade!

Mr Fischer Great new group-set - looks great on the bike! Shifts as stops as well as 6800, but no better or worse from what I can tell so far. Watched some YouTube videos on how to install the front mech, requires a longer chain for me than 6800 using the short cage and used the B screw to tighten the chain slack out. Italian bottom bracket requires a tool, I didn't have and an adapter is not included. Brake wires are easier to install. Also be careful not to stretch the hoods and leave them on the lever for the install, just peel them back. Brake clearance for 700 by 28, short cage will support a 30 tooth cassettes, and grippy hoods, and improved darker color, are the biggest upgrades.

Mr Stevenson Cheapest on the internet, and next day delivery. No instructions included so check out YouTube or download the instructions in advance, as some of the cable routing, particularly the front mech, is slightly different to past versions. Gone with 11-30 cassette and the intermediate chainrings (46/52), feels more natural than the compact double and spending less time in the 11, I don't spin out on slight descents as I did before with the compact double. Shifting is much slicker than the Sram Red 10 speed I replaced but one week later and I'm still fine tuning as downshifting is sometimes slightly slow - feels more gentle and refined than the aggressive shifting of the Sram. Less effort is needed to perform shifting than with any 10 or 11 speed groupset I've used before.

Randall The new front and rear derailleur updates are very nice. Love the color scheme. Had no issues with install. Highly recommended!

Mr Lewis Everything looks good and what you'd expect from Shimano. This is part of a total rebuild of my main road bike. Note, there is no adaptor tool supplied for the BB so you will have to order one separately if you don't have one already. Also, and this is no issue either, installation manuals can be downloaded in pdf form from Shimano's website. You need the dealer manual.

Mr Murphy 50/34 Chain rings, 11-32 Cassette replacing a 105 triple groupset. The step up to Ultegra is a complete step change in shifting, responsiveness and speed of change. The package came with all the necessary cables and sleeves, I downloaded the dealer manuals to give me a better understanding of the fitting. Covered 5-600 kms so far with no problems and very happy with the purchase. Delivery and boxing of the kit were first class (DHL to NZ) so no hideous customs clearance charges from NZ post.
