Interfacing with modern electronic groupsets means there's an app experience. Like the new top-level Dura-Ace 9200, Ultegra R8100 features semi-wireless shifting, meaning that the two derailleurs are wired to an internal battery but the shifters communicate wirelessly with the rest of the system. However, within that, there are details that speak to the efficiency storyline. A year later, in the beginning of 2019, SRAM brought its own version of 2x12 shifting to market. 11-12-13-14-15-17-19-21-24-27-30-34T. It also uses a semi-wireless design similar to that of the FSA K-Force WE. Visit our corporate site (opens in new tab). This setup allows riders to modulate their braking more easily and precisely. Thats a combined difference of 67g. In the multishift setting, you can set how many gears it will move through when you hold the buttons as well as how fast it will move. The C50 (WH-R8170-C50-TL) is designed as an all-rounder with a great balance of drag, lateral and driving rigidity, periphery and overall weight and controllability, according to Shimano. This provides riders with better index finger and thumb grip on the hoods and better three-finger grip behind the brake lever, whilst still giving easy access to the shift lever in the drops. The app will detect the derailleur and the connection process will start. It also happens to work well when you've got your hands up near the top of a road bike STI. The new Ultegra R8100 groupset features two new 12-speed Hyperglide+cassettes: 11-30T and 11-34T ratios. Shimano says the Ultegra R8100 group is about 8.2 g heavier than the R8000 series. Controlling the bike computer from these buttons feels like magic. Shimano says that it has worked on driving rigidityand claims that the Ultegra C36 is 9% stiffer than the existing Dura-Ace C40-TL wheel. Each cog makes for smoother transitions between gears, which should help promote smoother and more efficient pedalling. He has won his category in Ironman UK 70.3 and finished on the podium in both marathons he has run. Differences in construction mean that Ultegra ST-R8170 shifters weigh more than Dura-Ace ST-R9270 shifters: 391g versus 350g. Check them out in this week's five cool things also featuring Specialized, Rapha, Altura and Tifosi, Transcontinental Race: Defending champion Fiona Kolbinger has purse and tracker stolen while sleeping, Near Miss of the Day 806: Shocking footage shows driver reversing at cyclist and running over dog, STI shifters (pair, for mechanical brakes), STI shifter with hydro disc brake calliper and hose (per unit), Second-tier groupset moves from 11-speed to 12-speed, Its available with Di2 (electronic shifting) only, Shifters communicate wirelessly with the rest of the system (disc brake version only), Shimano claims faster derailleurs than previously, Includes a power meter option for the first time, Features full-carbon tubeless disc brake wheels, Available for both disc brakes and rim brakes. There's still a central battery, good for approximately 1,000km of riding per charge, but now this battery has only two wires. I can sit there for hours comfortably. There's plenty of power for strong braking performance even without moving to the drops for the best leverage on the brake levers. The hoods curve inwards somewhat and are slightly taller than before. One runs to the front derailleur and one runs to the rear derailleur. If you want 46-36T gearing forcyclocross, youll have to stick with an R8000 11-speed 46-36T chainset. Heres why you can trust us. It takes a moment to connect and each time it will ask you if you want to change the default passcode. Shimano focused on improving the aerodynamics of the wheels, using faster and more stable profiles used across the range. The Ultegra C50 wheelset weighs 1,570g (698g front, 872g rear). Deciding which system you choose is more about preference. The equivalent Dura-Ace WH-R9270-C50-TL wheelset has a claimed weight of 1,461g. If you dont want to subscribe, please turn your ad blocker off. Using the buttons on the top of the hoods to switch screens on a bike computer feels like magic and there are no pressure points. It recommends that components from each groupset are used together but you could use Ultegra Di2 shifters and Dura-Ace derailleurs if you wanted; theyll work together. Height: 5'9" The increased height is in part to give riders a more secure grip on the hoods over varied terrain, but they also had to be grown slightly due to the added wireless transmission technology. At one point I tried an older tablet to see if an older version of Android would be more stable. It's more efficient and provides better movement when paired with small mountain bike levers. Training with watts has become more and more common among riders, so Shimano wanted to make sure that its second-tier group also had a power meter. Instead of using the gear shift buttons, you do it in the app. It's been a long-standing complaint that the Di2 buttons are small and hard to differentiate between. Rim brake versions of the system will be manufactured, but Shimano plans to prioritize manufacturing and distributing the disc versions of the groupset. I needed to micro-adjust the position of the derailleur. With SRAM and Campagnolo there's a system to put the groupset into adjust mode then you press the gear change buttons to make tiny movements one way or the other. BA1 1UA. The year 2018 seems like a lifetime ago given where the world has gone since then but four years ago Campagnolo dropped the first 2x12 groupsets into the market. The most notable changes are the 12-speed drivetrain and an evolved wireless Di2 platform, which delivers even faster shifting across all 12 gears. We send him off around the world to get all the news from launches and shows too. Although the levers transmits sift signals wirelessly, the company says the new system manages to get a 58 per cent reduction in rear derailleur shifting time and a 45 per cent reduction in front derailleur shifting time, and thats compared with the pervious generation of Dura-Ace. Over and over the app crashed before fully connecting. Thats an interesting development because with SRAM eTap and Campagnolo EPS systems its impossible to press one shift button when youre aiming at another, but it could happen with previous generation Shimano Di2. There are two parts to making this work. For comparison, a Dura-Ace WH-R9270-C36-TL wheelset has a claimed weight of 1,350g. While older versions connected through junction boxes, the whole system now revolves around the rear derailleur. Making the choice for Shimano Ultegra means more space between the frame and the chain. There are three different rim profiles, the height in millimetres included in each model name. He will happily talk for hours about the minutia of cycling tech but also has an understanding that most people just want things to work. Shimano reckons theyll last 1.5 to two years with typical use. 2008present unless otherwise stated. Shimano has updated its second-tier Ultegra groupset, making it 12-speed and available only with electronic shifting, and it includes a dual-sided power meter and full-carbon tubeless disc brake wheels for the first time. The wheelset weight is 1,649g (738g front, 911g rear). Although he rarely races, if you ask him to ride from sunrise to sunset the answer will be yes. The fact that Ultegra ST-R8170 shifters are powered by CR1632 batteries and operate wirelessly simplifies installation and means that theres no need for shift cable ports in the frame or handlebar. The upgraded brakes are another place where the efficiency story shows up. In line with more modern road tires, the Ultegra wheels feature wider 21-mm internal rim widths. Mat has been in cycling media since 1996, on titles including BikeRadar, Total Bike, Total Mountain Bike, What Mountain Bike and Mountain Biking UK, and he has been editor of 220 Triathlon and Cycling Plus. Now it's time for Shimano to take its turn in the 2x12 spotlight with Dura-Ace R9200 and Ultegra R8100. document.getElementById( "ak_js_2" ).setAttribute( "value", ( new Date() ).getTime() ); Get the digital edition of Canadian Cycling Magazine. The updated Di2 system with wireless shifters makes installation easier than before. We've also covered our initial impressions of Shimano Dura-Ace R9200 but now it's time to talk about what it's like to ride Ultegra R8100. Right hand hard, left hand easy, both hands for the front is a genius system and the giant buttons are a joy with gloves. 2000 to 2400 is a 20% increase, pretty big I'd say. looks a tad staged to me but still funny. You can change to Synchronized Shift (a function that automatically selects the most efficient gear on the front derailleur in synchronisation with rear derailleur gear shifting) or Semi-Synchro shifting (which automatically moves one, two or three gears at the rear to accompany a front shift), and alter the Multi-Shift settings (which control the number of gears you shift at a time), shifting speed and STI shift button mapping. Now, smaller-diameter SD300 wires connect the derailleurs to a single battery, whose charging port is integrated into the rear derailleur. The shifting is slower but there's a rethink of gearing with the goal being that you rarely need to shift the inherently slower front derailleur. Shimano says that the FC-R8100-P power meters rechargeable Li-ion battery offers 300+ hours of ride time. Now featuring Shimanos Servo Wave technology, brake performance is improved thanks to a faster initial bite point along with a wider control area. All three models use 1:1 standard spoke lacing on the front wheel. In the app, synchro shifting options mean you set multiple modes. The slightly heavier Ultegra power-meter crankset, however, is at least $380 cheaper than the new Dura-Ace. The system can now be bled without removing the caliper from the frame. The sprocket sizes on the 11-34 cassette are: It comes in 11-30 tooth and 11-34 tooth configurations. You decide if it's semi or full synchro shifting and how many gears the rear changes in response to the front. I haven't experienced a single crash since then. Canadian riders who spend time riding with winter gloves on will appreciate that Shimano has increased offset between switches, which makes it easier to differentiate between them. The cassettes are part of the headline features in that they now carry 12 sprockets but the details are all about speed and efficiency. When you are talking about the top tier groupsets from the three biggest manufacturers there's no real loser. In this case, that means there's efficiency beyond performance. This groupset will make upgrading to 12-speed easy for current Shimano users. It can take 12-, 11- and even 10-speed cassettes. Advertising, commercial: sales [at] road.cc The right hand controls the rear cassette and the left hand the front chainrings. Riders can set different shift speeds, different button assignments, program automatic shifting modes like Synchro and Semi-Synchro shifts, fine-tune shifting and connect to third-party bike computers. 11-12-13-14-15-16-17-19-21-24-27-30T. The Ultegra derailleurs function in the same way as their Dura-Ace counterparts, its just that a different construction means theyre a little heavier The Dura-Ace R9200 front and rear derailleurs are a claimed 96g and 215g, while the Ultegra R8100 weights are 116g and 262g. Shimano brake rotors have always looked amazing but they also offer outstanding performance, A separate bleed port and valve screw simplifies the bleeding process and its now much easier to bleed the system without removing the caliper from the frame, Ultegra Power Meter Crankset with Chainrings, Ultegra Di2 Shift/Rim Brake Lever Set (Left and Right), Ultegra Di2 Shift/Disc Brake Lever Set (Left and Right), Ultegra Hydraulic Disc Brake Set (Calipers and Levers) - Front, Ultegra Hydraulic Disc Brake Set (Calipers and Levers) - Rear, 12-speed gearing without any freehub change, Wireless front controls make for a more aero setup, Almost all the performance of Dura-Ace at a fraction of the cost, Simplified wiring and built-in wireless connection, Mobile app for customisation and maintenance, Visual indication of derailleur micro-adjustment in the app. Tel 01225 588855. https://www.cornwalllive.com/news/cornwall-news/man-24-charged-drink-dri Nearly time to start! The downside of that rethink is the 10-tooth cog and need for a new freehub as well as how close it puts the chain to the frame. Like Dura-Ace, Ultegra 12-speed cassettes come with a new spline fitting pattern, which is also backwards compatible with Shimano 11-speed freehub bodies. The one downside is the button arrangement. The result is that there is no longer any need to back off an acceleration or time an easy pedal stroke with your shifts, says Shimano. If you are considering breathing new life into an old frameset with an upgrade or shopping for a new bike, keep reading to see what we think of the latest Ultegra R8100. Shimano has provided other updates as wellnew shifter and hood designs, updates to brake performance (and maintenance) and three new carbon wheels all round out the latest Ultegra groupset. When it's time to brake, it feels natural to wrap one or two fingers around the upper part of the brake lever while keeping my lower fingers wrapped around the bars. Mat is a Cambridge graduate who did a post-grad in magazine journalism, and he is a winner of the Cycling Media Award for Specialist Online Writer. Rides: Orbea Orca Aero, Cannondale Topstone Lefty, Cannondale CAAD9, Trek Checkpoint, Priority Continuum Onyx. The extra buttons on the top of hoods are a joy and there's better pricing on replacement consumables such as cassettes and chains. The previous generation of Dura-Ace saw the debut of Shimanos crank-based power meter. But, to call it an Ultegra power meter is not exactly accurate. Shimanos proprietary strain gauges on both crank arms provide dual-sided data. Multishift is the ability to hold down the buttons for continuous movement across the cassette and synchro shifting can be either full synchro or partial. This time there's also an element of confidence and control thrown into the mix but the basic story is efficiency through Servo Wave technology. The Ultegra meter has the same electronics, same strain gauges, same internal rechargeable battery and same transmitter as Dura-Ace. Shimano says, "With the addition of ServoWavetechnology to brake levers, taken from Shimanosmountain bikeand gravelbraking systems, riders have a shorter free stroke and are able to get a more immediate connection between brake pads and rotors, allowing for more feathering or modulation of the brakes, resulting in more speed carry-through and more confidence in technical situations. It's no surprise that Shimano Ultegra R8100 is well-thought-out and performs at the highest level. The Di2 EW-SD300 wiring and batteries are new too. The rear derailleur now has integrated D-Fly connectivity, Shimanos term for the near-field network it uses to connect to a bike computer or its phone application. Instead, there's an almost I-beam-like central arm. Campagnolo is a lightning-fast shift experience that tends to be so fast and violent that it's upsetting to the whole frame. Shimano has ditched the traditional 53-39T option on the basis that many pros and competitive racers now prefer to use gearslarger than the conventional 53T, so it offers a 54-40T chainset at Dura-Ace level. I have always struggled to do the same thing with mechanical systems and often end up starting from scratch after hopelessly losing the adjustment. Just like older generations, the new Ultegra Di2 has three switches: one on top of the hoods and two lever switches. Shimano Ultegra R8100 covers everything a modern groupset should and it does it without needing a new freehub standard.
