There are a lot of new bikes out there with 30 and 32 tooth largest cogs. Which I am part of neither! If you feel a difference, it is a placebo effect. Shimano Ultegra is a bit more refined that Shimano 105, with lighter materials in some areas and details like more durable coatings on some parts Nevertheless, the weight difference is surprisingly small, less than 200g for a typical ensemble; most of the difference is in the brake/shift levers and chainset You get some idea of the relative costs though. They both mix value and quality in a package that is highly respected by most cyclists. This adjustment allows for more spring tension on the rear brake and a smoother brake. A 12-28 would have been far more practical and although I don’t think I “need” the 28, I do live in a very hilly area and would have embraced the spin if I had that smaller gear. At the time, this was probably at the top end of what you would pay for a carbon frame with 105. Ride faster and further, and have more fun on your bike. The frame geometry, design, and sizing/fit is going to matter more than the components (which is not that much weight and mostly the finish), the only exception is that if the Cannondale Synapse happens to be a disc brake version (in 2015, Canondale made both in the Synapse line). That is how I started. There is your performance increase right there! Is that the case? If the upgraded bike has upgraded wheels that is a big value. It might not look traditional hard core but it screams common sense. Many are going to disk brakes. As an Amazon Associate I earn from qualifying purchases. He started Sportive Cyclist in 2013 to record the journey to his first 100 mile ride, the RideLondon 100. 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. The 105 has a bit more ‘heft’. You won’t generally see Ultegra specified on aluminium frames. If your this has been happening since new possibly the chain is too long or the B screw needs adjustment. Ultegra’s barrel adjuster might simply be nicer from the perspective of a mechanic. Also, as before, I’ve just converted the GBP prices to USD. A groupset is a component manufacturer’s collection of mechanical parts, usually covering the derailleurs, shifters, brakes, chainset, bottom bracket, cassette and chain. 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.

The Cannondale Synapse Carbon 105 2021 model costs £2,200 ($2,838) whilst the Ultegra version is £2,700 ($3,483); Specialized Roubaix Sport (with 105) costs £2,750 ($3,548); the Roubaix Comp (Ultegra) comes in at £3,500 ($4,515). Shimano 105 and Ultegra are 2 of the most often picked groupsets by road cyclists. I’m thinking this is wear on those rear gears. 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… So I recently picked up a 1991 Cannondale SR800 that is wearing 105 (1055). I have been looking at carbon fiber, Trek, Specialized and Cannondale…there’s so MANY options. Unhelpfully, Shimano released products for, say, 2018, in mid-2017, so there might be the odd inaccuracy. My soft tail Ti mtb is going on 17 years, and the flexing chainstays move hundreds of thousands of times with no apparent change. 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. Size is most important of the factors you mentioned. Crankset / chainset – the bit the pedals attach to – chain rings, cranks – that sort of thing; Derailleurs – the bits that move the chain between the different chainrings (at the front) and the various cogs of the cassette (at the back); Shifters – attached to the handlebars – the bit you manipulate with your hands; Cassette – the bit in the middle of your back wheel – lots of teeth; The Giant Defy Advanced 2020 model costs £1,949 ($2,514) with Shimano 105 and £2,199 ($2,837) with Ultegra (£250 difference for the hard of mathing); Canyon’s Endurace CF SL Disc 7.0 with Shimano 105 is £2,099 ($2,708) and the Ultegra-equipped Endurace CF SL Disc 8.0 is £2,699 ($3,482). For what it’s worth, if you’re looking for a noticeable improvement in shifting quality, a full overhaul at your current groupset (be that 105 or whatever) will give you the best bang for your buck. Since I know you were all particularly taken by the concept of each groupset have a name and a number, Ultegra Di2 is also known by its East German spy code of R8050. Hear about each post as soon as I publish. 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). You are not riding great distances yet, and you don’t want a poorly fitted bike to destroy your riding enjoyment. Interesting and thoughtful comment. Dreraillers had to be changed to match the shifter. 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’ll certainly be thinking about getting Ultegra on my next bike. That’s another question, and something I’m, going to find out (and REI gives you a few months to try it out, then you can still return it, thus my snapping up the bargain price without having a bike there to try out on the spot-REI is a seriously great company!!). If they both seem about the same goes with the smaller size. For the time being, only Ultegra and it’s pro-sibling Dura-Ace have electronic rather than mechanical gear shifts. I found the upgraded bike at a local shop and the other bike I found online and the person is willing to ship to me for free. If you think 70g weight difference in shifters the pair (5800-6800) is going to make you faster than me good. The chainring’s shape blends nicely into the body of the Ultegra crankarm. Of the the articles on the web, this one answered my question best about whether or not I’d made a mistake by purchasing a new Cannondale Synapse with 105 after 24 years of riding two bikes that had, in succession, a 1993 model bike with Shimano 600 (which I believe became Ultegra the next year) and just plain Ultra on my 2004 model bike. Yo! Ce type de groupe réduit permet de con… we’re probably due an update of the Dura Ace range next). When I knackered the front derailleur, I replaced it with the equivalent Ultegra version (10-speed 6700). That being said I think my 10s can last my lifetime (I’m 65 now) plus many years. I happened to run into a 2015 Cannondale Synapse 3 the other day, for $2150. As things wear, replace them with a higher grade chain and cassette. ©2021 Beginner Triathlete. Of course the chain is also thinner in 11s. Tiagra and below, despite being perfectly adequate for your first few sportives (probably all your sportives) and for your daily commute, should be eschewed in favour of 105 or Ultegra as soon as your functional threshold power hits 150W. Posted 7 years ago That said, my bike is setup for 126mm dropouts and is a 7 gear rear with downtube shifters. I’ll probably stick with 105 on the basis that the 11-speed R7000 version offers a significant upgrade versus the 10-speed 5700 that is on my current Domane. They take very little effort to stop, yet they don’t catch bad enough to throw you over the bars. Thank you! 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. Anyways parts are readily available now for the 10s option. Want to know whether you should upgrade from 105 to Ultegra but can’t be bothered with all these pesky words? The shifter also feels much tighter with the Ultegra. What is your skill level and how much riding will you do? Elle est la déclinaison abordable du groupe DURA-ACE. Overall, I would say the Ultegra are comparable to the 10-speed Dura Ace, if not even slightly better (especially braking). Suite à la première partie de notre dossier sur les groupes route et triathlon, voici les détails des poids et prix publics conseillés pour les pièces ou groupes complets de ce millésime 2019/2020. It’s most helpful in working out which generation of a given groupset you have/you’re buying. These are links to online stores such as Amazon, Wiggle and Chain Reaction. Shimano 105 R7000 groupset — everything you need to know. My last bike had a Dura Ace 10-speed groupset, and the Ultegra brakes are better than those. 105 stayed firmly mechanical. I’ve got full Ultegra 6800 11 speed, mostly because I bought a year-end clearance Giant for $200 less than my LBS was selling a Domane with 105 10 speed. Let’s all make a commitment to lose a pound or two around our bellies. As we spend more time on the bike and rack up the miles, it makes sense to upgrade assuming your bike fit is dialed in. But the shifting was better but I was disappointed with the wheels shimano still do cones and cups for wheel bearings, and the cassette freewheel had lots of play . Thanks for the article, it came at the right time for me as I am looking for a new bike and still ponder between 105 and Ultegra…. When it comes to purchasing a gift for our babies, nothing says I love you like a new groupo. But saying that loosing a few kg/s would be the cheaper option. LJ, yes, still here by default I think. Ooh, I seem to be first. There may be compatibility issues with the levers but I’ve not tried it myself. After 105, there is Ultegra and Dura-Ace, both of which have mechanical and electronic shifting (known as Di2) versions. And it lets one run a larger range cassette. 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 . Canyon, Cannondale and Specialized upgrade other components as you move up the range (wheels, for instance). 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. (Harry Enfield I’m considerably richer than you). 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). Buying from a Local Bike Shop has a value because you’ll be given preferential treatment over someone off the street when you go in for subsequent work. Now, back to your originally scheduled article…. If you have to go 105 for the cost, you won’t be disappointed, but it is definitely worth it to think about upgrading the rear derailleur and possibly the levers. The upgrade from 105 to Ultegra is incremental from component to component and much can be done as parts wear because parts are interchangeable. 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.
