Hello! Still have the 105 calipers, so I think that is the only remnant of the original groupset. I happened to run into a 2015 Cannondale Synapse 3 the other day, for $2150. Hope this helps and is only my opinion. This assumes that you are able to go big/big with the shortened chain. Learn how your comment data is processed. Anyway, to aid comprehension, here’s a little table I knocked up to show the range numbers of the current and prior generations of top end Shimano groupsets: The dates show the ‘model year’ for when each new generation was launched. Shimano 105 contre Ultegra (trop ancien pour répondre) Eric LAMBERT 2004-08-23 06:42:31 UTC. Thank you for your reply. Check out our comparison of Shimano 105 v Shimano Ultegra. Right now I ride about 20-30 miles 2-3 days a week. There has been plenty of discussion here on the differences (or non-differences) in components, so whether there is any genuine performance difference between the two product lines is a matter for conjecture. Any opinions? The upgrade groupset parts as they become worn out. In reading all these comments one sticks out to me — yesterdays ultegra (i.e. The chain ring bulges slightly acting as a ramp for Ultegra’s asymmetrical chain to climb up onto the big ring. Clearly if you want electronic shifting, then Ultegra is, for now, your only option. Thanks Andrew. Back in the day, there was a big difference in smoothness of shifting, also weight between the groupsets. Cosmetically, Ultegra boasts a carbon shift/brake blade while the 105 sports an aluminum blade. Rather than you changing gear physically by pulling on (or releasing) a cable, electronic shifting uses little motors attached to the front and rear derailleurs in order to make the changes. talk of slightly crisper shifting, smoother shifting, faster, easier shifting or difference in durability has me laughing. I have tried this myself and can vouch for it. Because they’re both in the current ‘design generation’ (is that what we’d call it), they both share the modern-looking chunky crank design. Thank you. None the wiser, that’s where. I will note that my current bike is Ultegra, I got it 2 years back. Also, according to Shimano’s website Ultegra’s wider crankset design permits frame manufacturers to build wider bottom brackets—the part between the pedals inside the frame—and thu… I have a solution for you: I madez a YouTube on the subject. Can anyone comment on how the 2 compare? Ultegra offers crisper shifting and better power transfer. If the upgraded bike has upgraded wheels that is a big value. Just my 2c. I’m not a pro rider and I just use my bike for city riding. 105 weighs 200g more, all else being equal), which in the grand scheme of anything other than pro cycling is kind of irrelevant. Ensuite les 3 composants spécifiques Ultegra di2 (ST, FD, RD) sont à 500 euros et 1050 euros pour le Dura Ace di2. Showing the actual prices just complicates things further.). Well, let’s face it. The better you are and the more you ride the more you would appreciate the upgraded bike. As things wear you can upgrade to Ultegra if you want, or you can experiment with changes. I just did this on my Domane – new cables, cassette, chain, brake pads and chain rings – recorded in this series of YouTube videos – and the improvement has been amazing. Also the cables stretch. I changed shifters from 5700 105 to 4700 Tiagara keeping the 10 speed drive train. 105 (la référence. you could be deluding yourself because you spent all that extra money and would feel a fool if there was no functional difference. And yes, Dura-Ace Di2 is R9150 (it doesn’t take an Enigma machine to work out the pattern – although the fact that the prior generation used ’70’ to denote Di2 means perhaps you do need some codebreaking nouse). superficial difference in the lever tops which I would guess is to stop you from putting Ultegra nameplates on 105 levers. So true about what you wrote, seems the Ultegra make a difference for racing and for “looks” to be in the elite crowd. The newest 105 is very slick and, I suspect, the best value of all Shimano groupsets for serious cyclists. Its time to cut the crap. The bike was originally 600 Ultegra, so would be a nifty trick to upgrade to an Ultegra drivetrain over the long haul. Get enjoyable and helpful cyclo-info straight to your inbox. (And please remember to hit ‘Like’ on the video – it really helps me out with the YouTube algorithm – many fanks). it would cost shimano more to have different production lines than to just put the same parts in several levers it would cost more to make the cheaper levers cheaper. I did read that about the span being more than an actual year. That time occurs before you buy your bike, roughly a week after you’ve bought your bike, then on a weekly basis until you cycle off this mortal coil. Precise shifting and much better ergonomics. 10s 105 or Ultegra can be used with XT deore cassettes (sometimes derailleur needs to be changed) and this can allow expanded gear ratios for climbing. I would spend my money getting a comfortable frame with 105 components. Shimano didn’t come out with a ‘105 Di2 5870’. My local REI (US cooperative outdoor equipment chain of stores) priced the one I ordered at $1799, a ridiculously low price, and an expert there said I’d be surprised at how good the model 105 group-set is nowadays, and that I’d probably not be disappointed. I certainly saved enough to replace the brakes if I feel they are really inferior on the 105 compared to what I am used to. Healthy disclaimer though – the prices seem a bit all over the place. If that’s you, then you’ll be more interested in the price point of the full bike, which I’ve discussed above. You talked about wheels and I strongly agree that lighter wheels make a huge performance and fun improvement. The 40 cog is aftermarket, and I took out the 11 cog to make it work. That said, if I ever feel that getting electronic gear shifting is an absolute must – perhaps you count yourself in this category –  then clearly Ultegra is the only choice (assuming I/you don’t have Dura-oodles of cash for the top of the range alternative). Replace your cassette every two chains. I think I prefer the proportions of the crankset. It’s no longer as clear cut. As an Amazon Associate I earn from qualifying purchases. Fit Werx offers the most scientific and complete bicycle fitting services in New England, the Northeast and beyond. the 2015 Cannondale) is today’s 105 (the 2017 Trek). Absolutely not. Cela comprend, pour un groupe de transmission complet : les dérailleurs avant et arrière, les étriers de frein avant et arrière, le pédalier, la cassette, les leviers de freins, le boîtier de pédalier et la chaîne. So I recently picked up a 1991 Cannondale SR800 that is wearing 105 (1055). Size is most important of the factors you mentioned. I don’t mind spending $90 for calipers…the best brakes you can buy is never a bad choice in my opinion. The overbuilt structure of the crankset coupled with the chainring has far more of an advantage in power transfer over the 105 which doesn’t sport a hollow outer chainring. You finally succumb to the rule of n+1 and you start looking for your first ‘proper’ road bike. Now a (very) quick canter through the different elements of the groupset: If you want more of an idea then this article provides a pretty comprehensive overview of the various group sets on the market. If you feel a difference, it is a placebo effect. what does this turd know I hear you say to yourself in your head. As you discuss only 11 speed groupsets, my question is about upgrading from 105 10s to 105 11s or even Ultegra 11s? I assume the bike from the LBS is new and the online one used. According to Beginner Triathlete, Ultegra group sets weigh roughly 280g, or half a pound less than a 105 gruppo. That would be the first major upgrade for me. If not then they are likely ok and I wouldn’t change them. The extra spread is useful as I have an 11-32 rear cassette with a compact 50-34 chainset Devon hills are not very forgiving. OK, it was aluminum, but I don’t ride that hard to cause frame issues : ) After 10 or so years I upgraded from low end 105 to Ultegra and things were excellent. For me I bought 105 sets because of the price point.. The heavier groupset will make you stronger because it’s heavier, then later when you upgrade to the lighter more expensive groupset you’ll be stronger and faster. One of the biggest improvements with the Ultegra group lies within the crankset. That’s the thing – the price is almost the same but the 2015 has Ultegra and the 2017 has 105. The electro-versions of Ultegra and Dura-Ace have Di2 added at the end of their names to make it clear that no cables are required (though unlike SRAM’s wireless eTAP electronic system, Shimano does still require the use of wires). Which I suppose makes sense since one is two years old (but is new). Given I’m more Nosferatu than Nostradamus, this probably means that 105 Di2 is going to be announced tomorrow. Pour l'instant la partie commune à l'Ultegra di2 et au Dura Ace di2 coûte dans les 500 euros. If so, I like the 105 bike more. I found it helped me because my hands are arthritic and it really relieved the pain going to larger cogs. L’énorme avantage va être de retrouver une large plage de … No sign of a R7050. Today I found a 2017 Trek Silque 5 (I am female) for $2000 but love the color and the frame seems more comfortable. There is your performance increase right there! I would guess you’ll be able to find 10s parts for many years to come. I am trying to choose between a 2015 Cannodale CAAD 10 105 for $1100 or a Cannondale CAAD 10 with Ultegra for $1750. In the meantime I’ll go back to my heavy, but rugged Diverge that is probably 6 pounds heavier than most of your bikes, and still runs well on Sora . At the time, this was probably at the top end of what you would pay for a carbon frame with 105. Which I am part of neither! In addition, the machining of the ramps on the aluminum cogs of an Ultegra cassette are held to tighter tolerances. Ultegra is better than 105 – no doubt about that. They take very little effort to stop, yet they don’t catch bad enough to throw you over the bars. For both, you will need to add a freehub to ensure that … I think what I’m about to write is something of a cyclo-cliché, but that has never stopped me before, so… 105 is the first of Shimano’s “serious” or “proper” groupsets. Just a quick note about brakes: I read recently that while Ultegra were the highest rated rim brakes, 105 use the same mechanical action and should perform the same (I can’t compare as my winter bike has discs). L'ultégra n'a vraiment pas grand chose de plus qu'un 105 si ce n'est "l'effet" gamme supérieure . My last bike had a Dura Ace 10-speed groupset, and the Ultegra brakes are better than those. Once you find the problem change the chain and cassette then adjust alignment and the B screw. My summer bike is all Ultegra, and my winter bike has 105 shifters, mechs and an RS500 crankset. Le pédalier Shimano FC-5800 délaisse l’architecture à cinq branches pour celle à quatre branches héritées des groupes Ultegra et Dura-Ace, plus légère et plus rigide. If you ride significant miles you eventually start replacing components as maintenance items. This post might contain affiliate links for which we may make a small commission at no extra cost to you should you make a purchase. Unless your derailleur is bent I wouldn’t change it. Ce type de groupe réduit permet de con… As we begin to understand what we like and what we don’t like, after that 10,000 shift, we begin to appreciate ulegra and it’s smoothness. I am also looking at a Colnago CLX 3.0 Ultegra 2015. I didn’t love it, but did like the price and the components. When you are due for chain and cassette replacement switch to ultegra. A part 400 euros, il y a t'il une grosse différence entre shimano 105 R7000 et ultegra R8000 les 2 groupes pour un amateur comme moi. Overall, I would say the Ultegra are comparable to the 10-speed Dura Ace, if not even slightly better (especially braking). And then the next generation of Dura-Ace and Ultegra came out (i.e. Your logic is impeccable and it is exactly what manufacturers want you to think; whether it be a bike, a car or a computer. This was all quite straightforward (okay somewhat straightforward), until Shimano started adding an ‘R’ at the beginning of some of them, and I got a bit befuddled. So, for instance, in the article, 11 speed first appears in 2012 in Dura-Ace (9000), then a year later in Ultegra (6800), and then two years later in 105 (5800) and has yet to appear in the Tiagra line (presumably the 4800). Ultegra Di2 et Ultegra normal (le petit frère des Dura-ace, en un peu plus lourd et moins cher.L’équivalent des Force chez SRAM. That I am still asking these questions at age 66, and still riding at least 2K miles a year while working full time tells you how great a sport biking is!! Shes also comparing two different model bicycles (an endurance carbon bike from Cannondale with a women’s specific endurance carbon bike from Trek). My advice would be to focus on the frame and get as much 105 on there or better at the start, though I believe RS500 cranks are comparable to 105. The chain became an Ultegra and then the chain and cassette did. Dreraillers had to be changed to match the shifter. Purists might point to a little more finesse in the Ultegra front and rear derailleur, but there’s not much in it. Regarding 10s vs 11s you likely won’t notice a difference. This site uses Akismet to reduce spam. The rear is a different story. I remember when test riding bikes that the Ultegra shifters “felt” better than the 105. Why yes friend, it does. Can you include more on how these two group sets perform? In the case of LJ’s specific example, it’s pretty easy to decide: just ride both and then choose the one she likes more, since she is comparing two complete bikes with different designs. A final point is that it is well known that last year’s Ultegra is effectively this year’s 105, so a two year old bike with Ultegra is likely to be equal, perhaps inferior to the current model 105. 105 chains have a duller finish and due to a different riveting process, are more “flexy.” An Ultegra cassette substitutes the aluminum lock ring for the steel one found on a 105. Higher quality springs and pivots allow for solid, instant engagement in shifting. Currently I am riding a 20 year old mountain bike on paved trails. Pay a couple of hundred quid more and you’d be into Ultegra territory. Speaking to a few data points in the ‘endurance bike’ category (all of which are carbon frames): (For the USD prices, I just converted the UK prices at $1.29:£1 to give an indication. The 105 has a bit more ‘heft’. Indeed, the recent upgrade of 105 from 5800 to R7000 makes it even more comparable to Ultegra, performance wise.
