DESCRIPTION
Ultegra R8100 - Leave Time Behind
When developing the Ultegra R8100 series, Shimano took a holistic and 100 % performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere - whether in an everyman race, on the hunt for a personal best time or on a companionable ride.
As with the Dura Ace R9200, not only does Hyperglide+ make its way into the Ultegra's components, also its Di2 parts rely on Wireless technology to simplify operation and ensure smooth shifting.
Shimano Ultegra Di2 ST-R8170 STI brake/shift lever
Road bike riding has never been so much fun!
The ST-R8170 STI levers are not only characterised by their optimised ergonomics and even more precise dosing of the hydraulic disc brakes, but also impress above all with lightning-fast shifting processes, which are achieved not least through the
Wireless functionality.
The wireless connection also offers another advantage: without electric cables, installation is easier and the cockpit appears tidier. Nevertheless, the shift/brake levers still offer a cable connection (EW-SD300) for the use of additional shifters in the drops or the top of the handlebar. For numerous customisation and configuration options, compatibility with the improved
E-Tube Project
app, which, like previous versions, allows you to adjust shift modes (Synchro-/Semi-Synchro-Shift, Multi-Shift), shift speed and button assignment on the fly.
To ensure that the braking performance is in no way inferior to the shifting functionality, the Ultegra Dual Control levers feature
Servowave technology.
With the help of an extended brake control range, this ensures excellent dosing that offers optimum comfort and control even in challenging conditions. Of course, for individual adjustment, the levers feature the option of reach and free stroke adjustment.
Synchronized Shifting
Shimano's Synchro-Shift technology simplifies shifting immensely and significantly reduces the amount of decision-making processes that take place while riding.
Especially in decisive racing situations or when driving at the limit, drivers often have to complete a large number of decision-making processes in addition to the physical strain, which are then frequently disturbed and lead to wrong decisions. The fewer decision-making processes there are, the better decisions are made and the more attention is kept on the race. This is exactly what the Synchro-Shift technology makes possible, always selecting the optimal next higher or next lower gear ratio combination, regardless of whether the rear and / or front derailleur are used for this purpose.
In addition to the conventional manual mode, in which the front and rear derailleurs are controlled independently of each other, Synchro-Shift offers two further modes: Full Synchro-Shift |The front derailleur responds to the shifts made by the rider on the rear derailleur. Essentially, this means that only one shift lever with two shifters is needed to shift the rear derailleur and front derailleur.
Semi Synchro-Shift |
The rear derailleur responds to the shifts made by the rider on the front derailleur. In doing so, the rear derailleur automatically provides the necessary compensation shifting for low cadence jumps when shifting up or down at the front derailleur.
SERVOWAVE
Shimano's SERVOWAVE technology improves brake lever's modulation ability. Because the lever absorbs a lot of braking distance right at the start of its movement, the brake pads have disc contact more quickly and it remains more lever travel to adjust braking force. That is why SERVO WAVE brake systems are characterized by faster response, higher performance and shorter idle travel.
