shimano grx vs ultegra

Submitted by on Wednesday, 27 January 2021No Comment

• 10-speed mechanical. Cassettes are 11-28 (or closest) We've removed bottom bracket weight as these are frame dependant. Shimano says that the level of stopping power provided by the non-Servo Wave RX810 (pictured below), RX600 and RX400 levers is akin to Ultegra, 105 and Tiagra disc brakes respectively. Our guides include links to websites where you can buy the featured products. The true spirit of the sport New ULTEGRA R8000 series is "pro-proven" as it is a direct trickle down from DURA-ACE groupset. "Statistics are like bikinis. No chains were dropped. Shimano GRX – oder die Rückkehr des Zusatzbremshebels! I would agree most think country lanes should be safer than main roads but contrary to popular opinion, it’s not the motorway, main road, or the... Had some of my sympathy until the complainant hopped into the slipstream for a tow. As road bike component, the stress-free operation is one of the most important feature to lead all day riding comfort with braking and shifting. There are three types of chainset to choose from: 1x11-speed, 2x11-speed, and 2x10-speed (there is no dedicated 1x10-speed chainset). Does it require a client on the PC - I would presume so. (For completeness, Tiagra is … Email John with comments, corrections or queries. That said, GRX is still very good equipment and the range will suit the majority of those speccing their own gravel/ adventure bikes, as well as giving bike brands plenty of options when it comes to building new models. Dave Arthur said, "It’s just a shame Shimano wasn’t a little braver in offering a game-changing groupset to serve as a serious riposte to its rivals and offer the low and wide-range gearing that many people flocking to gravel bikes want.". Avec la gamme GRX, le résultat est une transmission fluide et silencieuse qui est spécialement conçue pour une pratique gravel. Ultegra and 105 are all-but-identical while Dura-Ace uses bearings so might be more durable/smoother in the long run.

Mat has been road.cc technical editor for over a decade, testing bikes, fettling the latest kit, and trying out the most up-to-the-minute clothing. Top GRX Gruppe: RX800. road.cc's Dave Arthur rode both mechanical and Di2 versions of GRX in atrocious conditions and said, "[The groupsets] kept changing gear with the usual metronomic precision that Shimano groupsets are known for. All of them use Shimano's Shadow RD+ technology which is designed to stabilise the chain on rough terrain by minimising unnecessary derailleur arm movement. Two sets of tubeless-ready wheels round out the GRX range: a 700C option (pictured) and a 650B option. Not surprising given GRX's intended use, you get hydraulic disc brakes across the board. The aim of road.cc buyer's guides is to give you the most, authoritative, objective and up-to-date buying advice. In other words, you sometimes have to mix and match. You can also find further guides on our sister sites off.road.cc and ebiketips. Die GRX-Serie folgt der Analogie von Shimano und bietet drei Abstufungen hinsichtlich des Preises und der Qualität – vergleichbar grdsl. If you go 12 speed SRAM you're gonna have to change wheels/freehubs anyway. If you're using a 10-speed system, you need the RD-RX400 which can cope with a maximum 36-tooth sprocket. There is no GRX 400 series chainset. Il ne s’agit pas d’une version retravaillée d’un ensemble de composants route. Each has a chainline that has been shifted outwards by 2.5mm compared with existing road components for increased tyre and frame clearance. The GRX shifters are supposed to be interchangable with Ultegra, but that doesn't necessarily mean a DR designed for 50/34 on the low side would or would not work with a 48/31 crank. Instead, there's a RX600 10-speed chainset with 46/30-tooth chainrings. When something wears out you'll have a load of options for replacement. The GRX shifters are supposed to be interchangable with Ultegra, but that doesn't necessarily mean a DR designed for 50/34 on the low side would or would not work with a 48/31 crank. Well now, I would certainly like to find out if the GRX 2X will work with a 5800 or 6800 front derailleur and a Hollowtech II BB. Not to suggest you should get Campy and do it, but an. Tel 01225 588855. Go to our complete guide to Shimano road bike groupsets for a rundown of Shimano's groupset hierarchy. Shimano’s GRX group offers clutch-based chain security, or as Shimano officially calls it, “integrated chain stabilizer mechanism,” both for 1x and 2x. BTW, they did fix the cable problem - it's called Di2. Will it shift just as well? This is the way that Shimano structures everything on its website. For this reason the front mech must be used with the matching GRX chainset (see above) which is similarly pushed outward from the frame by 2.5mm. (RX has 39t, meant for a road compact crank of 34/50) GRX is slightly heavier (255g vs 247g) I'm pretty sure that the reviews I read stated that the shifter hood has a different grip pattern and shape, and the actual shifters have a textured feel. The key difference between the GRX 800 chainsets and the GRX 600 chainsets is that GRX 800 uses Shimano's Hollowtech II hollow crank arm technology to reduce the weight. GRX provides sensible gearing for Shimano-equipped bikes – so hopefully no more roadie compact (50/34-tooth) chainsets on gravel and adventure bikes. Shimano empfiehlt den Einsatz von GRX-Komponenten zusammen mit MTB- (Deore XT, SLX, Deore) oder Rennrad- (Ultegra, 105, Tiagra) Kassetten und Ketten, die bereits Bestandteil des Lineups sind. Beides nicht konsequent auf den Gravel-Einsatz ausgerichtet. GRX is divided into three different levels: • RX800 Shimano Ultegra level and 11-speed. Help us to make it better. See below for details on those. I suffered no mis-shifts at all, no grinding gears, no evidence that it couldn’t cope with grimy riding. • 11-speed mechanical "The proven clutch-style rear derailleur and Shimano’s patented chainring tooth design ensured the chain stayed in place over the roughest tracks. Shimano offers dedicated GRX STI (combined shift and brake) levers, mechanical and electronic, which use what the brand calls a “gravel-specific ergonomic” lever design. If you don’t want to subscribe, please turn your ad blocker off. He has won his category in Ironman UK 70.3 and finished on the podium in both marathons he has run. There's a deeper scoop in the centre of the brake lever too, along with an anti-slip textured finish to provide a better grip. Note: SRAM eTa ", "It's affordable, easily upgradeable, works with many other Shimano components, and most of all works out on the road or trail to deliver a flawless shifting and braking experience in the worst of weather or trail conditions. The GRX 400 and 810 front derailleurs are based on these designs, but are designed for a smaller chainset (30/46 or 31/48 rather than 34/50). The crank is hollow tech II design so I am guessing it would work with the same BB, unless there is a different width for some reason. What else do you want me to say? Let’s look at GRX in detail, broken down into each component type. It leads to an enhanced sense of control. The result is much-improved control, comfort and braking when riding down steep descents or slithering down a muddy path. For this reason, it's easiest to decide first whether you want: • 11-speed Di2​ The GRX derailleurs sit further underneath the cassette than traditional road derailleurs – they don't extend so far out when you're using the small sprockets. Di2 1×11 looks a bit silly, because there is no left brake lever without shift lever. Our mission is to bring you all the news that’s relevant to you as a cyclist, independent reviews, impartial buying advice and more. It's this typically Shimano system-thinking that makes GRX a good investment. You can't have a complete RX600 groupset because there's no such thing as an RX600 rear derailleur, for instance; if you want an 11-speed mechanical rear derailleur you need to go for RX800 level. Voor de cassette kan je een 105 cassette of SLX 11-speed cassette (die nog steeds op de markt is) gebruiken. Shimano offers a mechanical shift ST-RX810-LA left lever that, when used with a 1x11 drivetrain, can control a dropper seatpost. For a better experience, please enable JavaScript in your browser before proceeding. Each has a rim with a 21.6mm internal width and 22mm depth, and the hubs are 12mm thru-axle. Would I need a new FD? Lower gearing (48/31 crankset for the GRX 800, 46/30 for the GRX 600 vs 50/34 for the Ultegra), the possibility to go 1x with a dedicated 1x rear derailleur and anti-slip levers on the brifters. Each rear derailleur has a stabiliser on/off switch that allows you to change the chain tension and minimise bounce. We send him off around the world to get all the news from launches and shows too. The inline hydraulic sub-brake lever (BL-RX812, pictured above) is an interesting option. Avec les transmissions GRX, Shimano propose donc désormais 3 … Cassette and chain options come from current road (Ultegra, 105, Tiagra) and mountain bike (XT, SLX, Deore) groupsets. I regularly asked the groupset to change gear in extreme circumstances, deliberately shifting under load and cross-chaining, but nothing I did invoked any reluctance.

"Overall, the experience is one of trust," said Mike Stead, talking about using GRX 600 in particular, "It shifts with typical Shimano 105-or-better accuracy, and the chain won't fall off unless you do something spectacular. Yes that rack in question was made in the EU, so no tariff. From what I can tell online, the GRX is more expensive with nothing to show for change in performance and my understanding is either will work with the GRX or Ultegra derailleurs the same. Better yet, it’s all inner compatible, so you can mix and match. The single ring chainsets use Shimano’s Dynamic Chain Engagement tooth profile – tall teeth that are alternately thick and thin, specially shaped to prevent the chain bouncing off on rough terrain. GRX represents Shimano’s first foray into single chain ring (1x) drop bar drivetrains, but 2x options are still available with a new wide-range pair of chainrings. Dave Arthur said, "The most successful aspect of the new groupset is the new hoods. And if I need a new FD, is the actuation ratio the same? Shifting is mechanical only. Pot, meet Mr. Black. The idea is that you can butt your hand up against the front end of the hood to stop it sliding over the top. Did it once, won't go back. The only exception is the new GRX front derailleur and 2x cranks have to be paired, meaning you can’t use an Ultegra crank with a GRX front derailleur or vice versa. Indice • Il gruppo Shimano Gravel GRX • Il test del gruppo Shimano Gravel GRX • Per chi è fatto il gruppo Shimano Gravel GRX • Considerazioni finali Il gruppo Shimano Gravel GRX. The GRX 800 series chainset is available 2x with 48/31-tooth chainrings, and 1x with either a 42-tooth or 40-tooth chainring. The decision to offer three ranges covering both 10-speed and 11-speed ensures it is an accessible proposition too. • RX600 Shimano 105 level and mainly 11-speed (although there is a 10-speed RX600 chainset too). Rather than unveil a standalone groupset, with GRX, Shimano has developed a whole new groupset ecosystem with three levels of performance on offer. We want you to be happy with what you buy, so we only include a product in a if we think it's one of the best of its kind. RX800, RX600 and RX400 ranges add new levers, derailleurs, cranks and more Shimano steigt mit der ersten spezialisierte Gravel-Komponentenserie gleich groß ein: 3 Gruppen-Niveaus von 10-fach bis 11-fach Di2, 1-fach und 2-fach Varianten sowie neue STI-Hebel mit anderer Ergonomie sind nur einige von vielen Neuerungen. As far as possible that means recommending equipment that we have actually reviewed, but we also include products that are popular, highly-regarded benchmarks in their categories. Just the 3 usual channels Power, Cadence and FEC? To compare the Ultegra RX to the GRX 2x (RD-RX810), the key differences are: GRX has a 13t tension pulley which should slightly reduce drivetrain resistance. Advertising, commercial: sales [at] road.ccView our media pack. If you're using a Shimano Ultegra or 105-level 11-30/34-tooth 11-speed cassette, you need to use the short cage Di2 RD-RX815 rear derailleur or a mechanical RD-RX810 rear derailleur (pictured above). Die Top Gruppe der GRX Serie mit dem Namen RX800, ist als mechanische sowie als elektronische Di2 Variante möglich. Shimano already offered the switchable, adjustable chain stabilization on its Ultegra RX800 mechanical and RX805 Di2 rear derailleurs , but now has five different GRX rear derailleurs. You can also buy STI levers and brake calipers in sets. Dave Arthur said, "The brakes coped with demanding high-speed descents and awkward low-speed tight downhills. The flat mount calipers and rotors are carried over from Ultegra with the same caliper design and rotor sizes, and as such the braking performance was familiar, powerful and consistent.". Your hands stay put on the hoods, and your fingers are able to brake and shift even when cold, wet and muddy. Instead, it has combined key technologies and components from current road and mountain bike road groupsets and added some brand new parts. "The change is more pronounced on the Di2 shifters. Now with the GRX line Shimano has made a clear distinction between technology intended for paved and unpaved roads. Editorial, general: info [at] road.cc Ausgestattet waren die Räder bis vor kurzem mit Rennrad-Schaltgruppen (Shimano 105, Tiagra, Ultegra) oder Mountainbike-Antrieben mit einem Kettenblatt (Sram Apex, Rival, Force). The flat mount brake calipers (BR-RX810 pictured) are the same design as the current road calipers – but with GRX logos – so they come with features like one-way bleeding and Shimano's Ice Technologies heat-dissipating finned brake pads and rotors.
