Justin Ervin Upgraded to this from Tiagra, needless to say significantly better. The weight difference is noticeable when compared directly.
Mr SCOTT Initially bought this for the aesthetics over the 6800, but truly realizing better power transfer which was an unexpected surprise.
Mr Bowen I replaced a worn FSA crank with this to go with my new DI2 groupo. Performs well and looks great. Thanks Merlin.
Mr Knight Bought to replace 10 sp chain set. Still running 10 sp derailleurs and all works smoothly. Great price and Svs from Merlin as usual.
David Replacing an Ultegra 6700, nothing wrong with the previous version but I wanted the 110BCD for oval rings. Looks great, really light. Top quality.
MJG Upgraded my current Di2 setup so needed a new chainset. Ultegra is a solid, attractive option that works reliably. Excellent price and fast delivery as usual from Merlin.
Steve F. What an upgrade from 105 5800, I put the entire 8000 group set on my bike and it is now about 1.4 lbs lighter according to the listed weights (quite noticeable indeed). I've only taken a few rides but already my average speeds have improved by at least 1 mph (obviously I live in the US) and I've already crushed multiple PRs on Strava. Much of this improvement can be attributed to the bike fit I had done but the Ultegra upgrade has undoubtedly helped. Pedaling seems smoother, more efficient and actually easier even though I went with bigger gears. I switched from a 172.5 - 50/34 to the 170 - 52/36 with a Dura-Ace BB and I have an 11-32 cassette. Now when I'm in the drops I'm not kneeing myself in the gut so breathing isn't a chore and and it's no longer a distraction and I have the gears needed for just about every occasion. The Ultegra components also look amazing, not that it should matter all that much but of course it does. Merlin was one of the few that actually had the combination I needed in stock and they shipped it out right away, the shipping costs are very reasonable as well.
Jordan Better than the Dura Ace 9000 crankset. Getting higher standards with every groupset
Mr Colborne Not much to say really, this is going on my new bike. Ultegra is bullet-proof no nonsense gear. I have full confidence that this will perform splendidly. Shipping to Canada, was less than a week and it arrived in perfect condition. Price was great and I'm stoked to have found this store.
RVH Seems great so far. Replaced SRAM Rival crankset. Seems to shift cleaner with Shimano chain and FD. Easy to install and set up.
Mr de Barros Replaced an FSA crank I had with this Ultegra R8000 and must say I am impressed
Mr White All you would expect from Shimano, excellent product. Replaced due to a worn outer chainring where for a bit more money I was able to swap out the whole chainset which was a direct swap out on Di2. Very happy
Gary Very pleased much stiffer than previous model, and looks great to boot with usual prompt merlin service
Duane Comins Had the previous 6700 Ultegra set and all I can say is the R8000 is a major improvement. Stiffer and quieter. Probably the best value for money crankset out there. Looks amazing as well.
Joshua I purchased this chainset to replace a 105 5800 chainset that had a warped large chain ring and a stripped chain ring bolt. So there was a fair amount of flex in my old one. That being said, it would impossible for me to overstate the stiffness and reactivity I experienced in my first test ride. Much more snap and responsivity, climbing I see a huge improvement in speed without increasing my estimated wattage. Once up to speed I notice first a higher cruising speed, but I found it was much easier to maintain my speed as well. Although I obsessively tune my drive train because of my ocd, it is all but silent. Claims of greater ability to cross chain in my experience hold true, and only seem to rub the front derailleur, even in the extremes, when I put excessive power through the pedals. Mind you I attempt not to cross chain as a rule, but occasionally I will take advantage of that extra gear while climbing without realising I`ve reached my innermost cog. Aesthetically I feel the finish is more in line with the current 105 variant, which I admit I prefer to the last ultegra finish. At the time of this review I only have 250km on the clock, but the chainset still looks like I just took it out of the box.
Mr Madrid Very stiff, good looks and saving some weight, great quality very happy with it
