Ive ridden Ultegra R8. This is of course not enough time to make any assessments regarding the longevity of the groupset and Ill update this article once Ive had time to really put it through the wringer. We were lucky enough to secure an exclusive first look at Shimanos new Ultegra groupset Matthew Allen talks us through his first impressions of it all while giving it a thorough fondle. Ultegra RD R8. 00. The new rear derailleur adopts Shimanos Shadow Geometry technology. Drift N Burn 365 2 Hacked here. Since its what everyone looks at first on a bike dont pretend you dont, well start with the rear derailleur. Ive been testing the short cage version of the derailleur here RD R8. SS, but the performance is unlikely to be drastically different, if at all, to the long cage version. The bike was outfitted with the proper, as Shimano intended it, extra stiff OS RS9. The bike was also fitted with an 1. Shimano gods intended it, OT RS9. Most notably, the Ultegra RD R8. Shimanos Shadow Geometry technology that has been used on its mountain bike groupsets for years now. Shadow Geometry shifts the majority of the mech below the cassette and chainstay. Shadow Geometry shifts the majority of the derailleur mechanism below the cassette and chainstay, keeping it out of harms way, leaving only the main pivot proud of the frame. 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. Tucking the mech well under the chainstays should in theory also make the new setup more aero friendly, and as we all know, aeroiseverything. 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. Shifting speed feels much the same as the previous generation, but this was hardly laggy, so no complaints here. Thoroughly wiggling it in a workstand, the tension of the cage pivot feels a little bit stronger than the previous generation, which should help to keep things quiet on rougher terrain. However, much to my chagrin theres still no sign of a clutch equipped or Shadow Plus as Shimano calls it rear derailleur that is directly compatible with Shimanos road shifters. Di. 2 or cable pull adaptors would be great, so can we please have this soon, Shimano The move to the Shadow style geometry means that the mech is now compatible with direct mount DRD derailleur hangers. This arrangement is said to stiffen up the connection between the derailleur and the frame, improving shifting accuracy. Will we see DRD mech hangers on road bikes of the futureA handful of mountain bikes use this system, but as far as Im aware, no road bikes have employed it as yet. Shimano has been gradually shifting to using hex heads over crosshead screws for its limit adjusters and R8. While this makes things a bit more multi tool friendly some screwdrivers didnt play nice with the JIS heads used on Shimanos derailleurs just remember that its not exactly difficult to round small hex heads, so make sure you use decent hex keys and keep things clean, and you shouldnt have any problems. Im not that fond of the new barrel adjuster design. Im not particularly fond of the new barrel adjuster design its lost the chunky wings of the old adjuster in lieu of a more compact one that has one little lip and some grooves to grip onto. You can still get a reasonably good hold on this, but I can foresee it being a little more tricky to shift should anything become seized or stiff. Ultegra ST R8. 00. The shape of the new Ultegra R8. Dura Ace 9. 10. 0The new Ultegra ST R8. Dura Ace 9. 10. 0 levers, with a slightly more boxy shape than 6. Im quite fond of the new textured hoods. Of course such assessments are purely personal, but I prefer this new shape over the very slightly more rounded old profile the flat upper surface sits nicely in your palm and seems to transition a bit more smoothly from the bars to the hoods. The lightly textured hood surface is also a nice touch and didnt cause any hot spots or chafing, even when riding without gloves. The revised shifter paddle shape makes it easier to shift from the drops. As with Dura Ace 9. With the new design, Ive found it slightly easier to reach out and find the paddles when riding in the drops. The throw required to drop a gear has been reduced on both sides, with the throw required to shift up the cassette also reduced. I suspect this will be a very welcome move for those with smaller hands. For my larger phalanges, this resulted in a pleasingly light feel at the lever. You could argue that this makes it slightly easier to inadvertently hit the paddle and drop a gear, but I didnt find this to be the case. A 2mm Allen key is now used to adjust reach. Reach adjustment is as easy as before though a 2mm hex key is now used instead of a flat blade screwdriver to make adjustments and does appear to have a slightly greater range of adjustment than the previous generation. Thank goodness weve moved away from using those stupid little spacer blocks of old. Ultegra BR R8. 00. The new Ultegra R8. The new Ultegra brakes look almost identical to the new Dura Ace 9. Ultegra groupsets two tone finish. The brakes are a bit beefier overall. The brakes have been beefed up overall, with the backing plate and both arms all getting a touch chunkier. The thin booster bar is just visible between the two brake arms. The new brakes also include the same booster bar that was introduced with the new 9. 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. Shimano has made no specific claims as to how much stiffer the new R8. Dura Ace brakes are reported to be 4. Shimanos efforts seem to have paid off, with the power of the new Ultegra R8. Ultegra 6. 80. 0, which was hardly lacking in oomph. Modulation has also drastically improved. Setup obviously plays a big role in braking performance, but I think theres some truth in Shimanos claim that it has modified the braking curve to be more linear in a bid to make braking more predictable during a hard stop, theres a pleasing level of squidge at the lever, allowing you to really control the amount of power and avoid locking up the wheel.
