Shadow: Shadow design features a super low profile design and optimised slant angle for super light shifting action. Shimano has just released its new R7000 105 groupset, which is pretty much the only groupset any of us will ever need. I'd say that Ultegra is just a tiny little bit more refined throughout, but whether it is worth the extra expense is for you to decide. Conclusion Few are likely to damage a derailleur by catching or bashing it off something while riding on the road, but given that the new Ultegra groupset will inevitably see time used for cyclocross and gravel, this is a welcome move. Overall, shifting on the new derailleur feels improved rather than drastically different — the feel at the lever is slightly lighter and overall more satisfying, with an absolutely delightful metallic ‘cla-chunk’ as the chain climbs the cassette.The new brakes also include the same ‘booster’ bar that was introduced with the new 9100-series brakes. This thin metal plate sits between each of the brake arms, bridging the gap between the pivots and is said to “reduce deformation and improve braking efficiency.” 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, For me, the biggest difference of R8000 over 6800 is the shape of the brake lever. The curve for your index finger is more pronounced and if, like me, you like to wrap your finger around the bar when on the hoods then you'll find it very comfortable.

Shifting speed feels much the same as the previous generation, but this was hardly laggy, so no complaints here. 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.Ultegra is lighter, too, with our scales weighing it at 2,303g compared with the 2,413g of the Campag. The lever is carbon fibre, which is one difference over 105, and both it and the paddle behind offer very light yet precise shifts, thanks to the reduction in swing of both to change gear. 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. 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.

Since I started testing the new groupset, many have also asked me whether it is as good as Dura-Ace 9000 and I’d have to say, yes, pretty much. 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. Particularly when I am on the big ring, and the 5 smallest gears, the transmission produces a noise which seems to come from the rear derailleur (and more precisely at the level of the top pulley, where we see the chain that seems to "vibrate" - see video).Working with your 11-speed groupset and composed using a lightweight aluminium pulley cage that goes a good way to reducing weight without sacrificing your shifting power or performance, this rear derailleur boasts an incredibly broad gear ratio. Ranging from 11-28T and going as far as 11-34T you can rest assured that you have the ability to take on the impending climb and pursue it to its conclusion. 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. The second advantage is that the design makes it possible to mount bigger cassettes, with both the short and long cage versions. With the long cage derailleur this means that you can mount an 11-34, which will be useful on climbs. From a technical point of view it creates a bigger chainring, which allows you maintain the normal crank ratios but with a bigger cassette. There are multiple cassette ratios to choose from for different terrains. For example, the cassettes ending at 25T are used more on the flat and slightly sloping roads. The 28T is used for hilly roads and the 30T, 32T and 34T for real mountain rides. The 14/28 is mainly used for cyclists who want the smallest possible transitions, for the ideal cadence. All this, of course, taking into consideration whether you ride compact, semi-compact or double.

The Ultegra R8000 rear derailleur has Shimano's Shadow-Link design. With this design, which you also see on the Dura-Ace R9100, the derailleur is further recessed below the cassette, which has two key advantages:Price Matches may only be honored on identical items.
