What they reveal is suggestive, but what they conceal is vital. The result is much-improved control, comfort and braking when riding down steep descents or slithering down a muddy path. He has won his category in Ironman UK 70.3 and finished on the podium in both marathons he has run. 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. We’re impressed by what Shimano has delivered. 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.". Dave Arthur used the RX810-F front derailleur and said, "Front shifts [were performed] well despite that 17-tooth jump between the two rings and being asked to do so in adverse conditions and with a regularity that rolling terrain requires.". 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. Shifting is mechanical only. The only difference is in the GRX RX-815 Di2 shifters, where the diagram shows the higher pivot in the brake. SHIMANO GRX, avec son ergonomie spécifique gravier, ses options de changement de vitesse optimisées, sa robuste fiabilité et sa transmission silencieuse et stable, se distingue des autres dans le monde des composants. The world’s first dedicated components for gravel adventure No chains were dropped. Pour simplifier les choses, Shimano a conçu le GRX pour qu’il se marie aussi bien avec les cassettes et de chaînes des gammes VTT (Deore XT, SLX ou Deore) que des gammes Route (Ultegra, 105, Tiagra) déjà existantes au catalogue de la marque. Your hands stay put on the hoods, and your fingers are able to brake and shift even when cold, wet and muddy. 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. Hier findet ihr alle Infos. 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. It looks like there is a 46/30 option too: Here's what I learned after some reading both the link Wetworks posted and on the Shimano website. You can then look at the options available within each category. Come join the discussion about bike parts, components, deals, performance, modifications, classifieds, troubleshooting, maintenance, and more! I suffered no mis-shifts at all, no grinding gears, no evidence that it couldn’t cope with grimy riding. Instead, it has combined key technologies and components from current road and mountain bike road groupsets and added some brand new parts. Shimano GRX also includes 1x11-specific BL-RX810 and BL-RX600-series left side hydraulic disc brake levers with no dropper or shift internals. Each has a chainline that has been shifted outwards by 2.5mm compared with existing road components for increased tyre and frame clearance. Shimano’s GRX group offers clutch-based chain security, or as Shimano officially calls it, “integrated chain stabilizer mechanism,” both for 1x and 2x. 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. Our guides include links to websites where you can buy the featured products. "The mechanical groupset worked beautifully [and] GRX Di2 is a clean shifting groupset that proved unflappable over three days of riding. Yeah, I don't think there's any reason I would consider 1x - the 2X GRX with the 31tooth ring is sweet though. In other words, you sometimes have to mix and match. 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. 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. The true spirit of the sport New ULTEGRA R8000 series is "pro-proven" as it is a direct trickle down from DURA-ACE groupset. Let’s look at GRX in detail, broken down into each component type. 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. I would really like to see Shimano attack the cable eating shifter problem before they go to the next generation of products. Here's some more information on how road.cc makes money. Based on the Ultegra R8000 lever, the GRX 600 lever is roughly the same shape, with three critical differences: the rubber hood material, the lever pivot point and the lever shape/material (noting that the higher-spec GRX levers are a different shape again, with taller hoods and Shimano's 'Servo-Wave' mountain bike brake technology). (RX has 39t, meant for a road compact crank of 34/50) GRX is slightly heavier (255g vs 247g) Ultegra and 105 are all-but-identical while Dura-Ace uses bearings so might be more durable/smoother in the long run. Rather than unveil a standalone groupset, with GRX, Shimano has developed a whole new groupset ecosystem with three levels of performance on offer.
