Product 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-R8150 STI brake/shift lever

Compared to the disc brake version, the Ultegra ST-R8150 dual control levers rely entirely on a secure cable connection and the low weight of a rim brake system.

In terms of ergonomics and shifting performance, the STI levers are in no way inferior to their disc brake counterparts. The clearly defined click-feel of the shifting aids not only ensures intuitive, but also fast gear changes. The optimised shaping and surface structure of the horns and brake levers guarantee outstanding grip and excellent braking power transmission. Of course, for individual adjustment, the levers feature the option of reach adjustment.

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. For connection to the BT-DN300 battery and use of additional shifters in the drops or the top of the handlebar (each sold separately), the Shimano ST-R9250 dual control levers feature 2 cable connections.

Ports: 2x EW-SD300

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.

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.
