I love using R8000, it's pretty much my favourite groupset – and I've ridden virtually every setup going this year, at least from Shimano and SRAM. It's no lighter than the outgoing edition, but overall it works just a little bit better – more an exercise in refinement than a major overhaul, but very welcome nonetheless. Verdict

The added weight for the clutch is about 30-40g. The RD-RX805 model has a claimed weight of 280g (compared to 249g for the RD-R8050) and the RD-RX8050 weighs 248g (compared to 210g for the RD-R8000).Chain reaction Cycles and CRC are trading names of Wiggle Ltd (In Administration) registered in the United Kingdom at 1000 Lakeside, Suite 310, Third Floor N E Wing, Portsmouth, Hampshire, PO6 3EN, The hydraulic R8020 versions are Ultegra-specific, whereas in the past the levers were 'Ultegra level', and they have become so small considering the fluid reservoir that there is barely a difference between them and the rim brake options. Chainset On my other bike, I have an "old" Ultegra 6800 groupset which is perfectly silent. I have never had a noise problem with it in 3 years and the bike is set up the same way as the other two. The company unveiled the new RX derailleur with its 2019 line of products last month and we were the first to bring you official details on the derailleur as well as the new 105 groupset. We take a look at the new clutch-based derailleur, consider its future in cyclocross and offer our impressions after riding with it over 100 miles of Minnesota gravel. The New Clutch-Based Shimano RX Rear Derailleur

I think i end up with about 4-5mm of gap between upper pulley and the 30T cog - If this shift has i grinding noise, i found that the gap is too small and need another 1mm or 2 to become noisy but with no "grinding" (and i don´t meen grinding noise like bad indexing - its different på grinding, more like the upper pulley hitting the cog type of sound) Since the beginning of 2018 I've ridden the new Ultegra on loads of bikes in a range of setups including mechanical and electronic gear systems, and both rim and hydraulic disc brakes, so this has turned into a bit of a longterm test review as I've really been able to put it through its paces. Shimano also had its pro team liaisons at the Almanzo event. They were somewhat mum on the Ultegra RX’s future in professional road and cyclocross racing. Word about the Ultegra RX first came out when the Trek-Segafredo team test rode the clutch-based derailleur before the Tour of Flanders spring classic. The team did not race with the Ultegra RX in Flanders, but they did at Paris-Roubaix. As one of the reps pointed out, the impact of the new derailleur did not show in the results. You can use this kit with all mechanical 11-speed Shimano shifters. So whether you have Ultegra, 105 or Dura-Ace, this derailleur will work perfectly with the shifters.

Stay tuned as we take a closer look at what the Shimano-sponsored athletes ride this fall. Ultegra RX Ride Impressions The hood shape is very similar to 6800, but the rubber cover has had a pattern added for extra grip, like Dura-Ace, not that I really noticed a difference.

Both models come with a GS long cage that fits cassettes between 11-28t and 11-34t. Lawrence explained the company added room for the 34t cog after test rides on the steep gravel roads in Colorado. That’s pretty low for road 2x gearing, but a few steps away from the 11-42t many 1x users are used to (in case you’re thinking about a RX805 single chain ring setup).Shifting speed feels much the same as the previous generation, but this was hardly laggy, so no complaints here.

Along the way I've also ridden every Shimano groupset from the 8-speed Claris through to the top-end Dura-Ace Di2, which has helped highlight just how good this groupset is. A number of European cyclocrossers, including Mathieu van der Poel, Sanne Cant and the Telenet Fidea team, race on Shimano components. Although SRAM’s clutch-based derailleurs have become a favorite for many U.S. cyclocrossers, the Shimano reps said none of the athletes have committed to using the new clutch-based system this fall. Shimano’s new Ultegra R8000 cassette supposedly offers “HIGH-PERFORMANCE GEAR COMBINATIONS” and is virtually indistinguishable from the previous generation. It shifts just fine and weighs the same as the old one. Some readers will likely note Shimano already has clutch mountain bike derailleurs that can be paired with electronic shifting for 1x systems. With the new Ultegra RX derailleur, Shimano expands compatibility to mechanical road shifting and suggests there is a benefit in having a clutch rear derailleur with double front chain rings when riding gravel. All the prices listed here are the official Shimano recommended retail prices and as we all know you can get things like groupsets a lot cheaper online.series braking was considered benchmark and I think Ultegra R8000 exceeds it in terms of power and modulation. Shifting is also on par, and while R8000 weighs a touch more, you can easily lose that weight elsewhere on the bike.
