Time Trial and Triathlon Gear Upgrade Kit Shimano Ultegra 12-speed Di2 Disc R8170 / R9180

The upgrade kit for the Shimano Ultegra R8100 Di2 Disc Flat Mount components, featuring the ST-R9180 time trial disc shift/brake levers and, optionally, the SW-R9160 handlebar-end shift levers. The new Shimano Ultegra Di2 R1800 series disc brake components, the affordable version of Shimano’s electronic road bike components.

The 12-speed Di2 Ultegra time trial components use the Dura-Ace 11-speed Di2 TT shift levers; these do not have a wireless interface and are connected via cable. To ensure they function correctly with the 12-speed system, all Di2 components must receive the latest firmware update. This can be done after installation using the Shimano app and a mobile phone, tablet, PC or the SMPCE02B diagnostic device. We can also carry out this update for you as an optional service.

Shimano Di2 installation:

The TT Di2 shift levers are connected to the SM-JC41 distribution box using the EW-JC130 Y-cable. From the SM-JC41 port, the EW-SD50 cable runs to the EW-AD305 connector. From the EW-AD305 distribution box, the EW-SD300 cable then runs to the battery, as do the cables from the rear derailleur and front derailleur.

Shimano Ultegra RD R8150 Di2 rear derailleur:

The new Ultegra rear derailleur is the centrepiece of the new 12-speed Di2 components. It provides the wireless functionality and connection to external components, and also houses the charging port. The rear derailleur also houses the transmitter, which enables wireless communication with the STI shifters and other external devices, including those from third-party manufacturers. Furthermore, it features the status LED and the adjustment button, which is used, for example, to switch between Synchro-Shift modes, meaning that the previous Junction A port, SM-RS910, is no longer required.

Precise, lightning-fast shifting at the touch of a button, in any situation. The Shimano Ultegra Di2 RD R8150 rear derailleur is even more compact and lighter than its predecessor and features E-Tube connectors for extremely easy installation. Equipped with a crash mechanism that disconnects the connection to the motor in the event of strong external forces to prevent damage.

Shimano Ultegra FD R8150 Di2 front derailleur:

Lighter, faster and more aerodynamic: the Ultegra 12-speed Di2 front derailleur. Designed for chainring sizes ranging from 50/34 to 54/40 teeth, the new 12-speed Ultegra Di2 front derailleur operates even faster and more precisely. More compact and faster than ever before, the Ultegra R8150 front derailleur delivers shifts with digital precision in all conditions. By combining Shimano’s new Di2 platform with the road bike version of Hyperglide+, the Ultegra R8150 front derailleur shifts between chainrings as quickly and seamlessly as no other model on the market.

Shimano Dura Ace Di2 STI R9180 TT Disc Shift-Brake Lever:

With the ST-R9180 STI Disc shift-brake lever, Shimano introduces a highly compact shift-brake lever designed for time trial handlebars, hydraulic disc brakes and the electronic Di2 shifting systems, marking another milestone in the development of hydraulic disc brake systems for road bikes. The new Dura Ace Di2 STI levers offer optimal ergonomics thanks to their adjustable grip width. The Dura-Ace Di2 shift-brake levers are fitted with carbon brake levers. They shift extremely quickly and precisely. Thanks to electronic transmission of shift commands, these are executed without delay. Operation is similar to that of mechanical STI levers, with shifting at the touch of a button. The new 11-speed shifters are also equipped with the programmable Multishift function. Shimano’s engineers have succeeded in integrating a mineral oil cylinder, including a complete braking system, into the still very compact mechanical shift-brake levers. The brake levers are made from multi-layer composite; this technology guarantees maximum stiffness, durability and a lightweight design. Thanks to the improved position of the brake cable, a smooth braking action is achieved, leading to optimised control in extreme conditions. The Dual Control shift/brake levers can be optimally adjusted to the rider via a grip width adjustment and are also very well suited to riders with small hands. With the new shift levers, shifting can be performed much more quickly. This is achieved through a 20 per cent shorter cable. The grips feature an ergonomic design for greater comfort – even over long distances.

Shimano Di2 STI SW-R9160 TT Bar-End Shifters:

The electronic Shimano time trial shift lever for the Di2 system. The Di2 shift levers SW-RW9160 are mounted on the handlebar ends of the time trial extensions. Optionally, the SW-R9150 secondary shifter can also be fitted, allowing the rear gears to be changed quickly and without re-gripping in any riding situation. The SW-R9160 Di2 shifters with their single-button design offer the ability to operate the front derailleur and rear derailleur in the aero position

Shimano Ultegra Disc Brake Caliper BR-R8170:

The BR-RS8170 road bike disc brake calipers for the 12-speed Ultegra groupset. These calipers are compatible with all Shimano disc brake levers. Recommended brake discs: RT-MT800. Thanks to the 10 per cent greater spacing between the brake pads, the brakes can be adjusted more effectively and noise is minimised.

The new Ultegra BR-R8170 brake caliper offers improved modulation, a quieter braking system and an extremely simple bleeding procedure. The Ultegra R8170 disc brake caliper offers road cyclists a completely new sense of control thanks to its improved modulation and faster-acting initial braking force. Despite its flatter design, the system produces less braking noise than ever before and is easier to maintain. The bleeding system has been redesigned and made significantly simpler.

Synchro-Shift technology

Synchro-Shift technology greatly simplifies gear changes and significantly reduces the number of decisions riders have to make whilst riding. Particularly in critical race situations or when riding at the limit, riders often have to juggle a multitude of decisions alongside the physical strain, which can frequently lead to errors and poor choices. The fewer decisions there are to make, the better the decisions will be and the more attention can be focused on the race. This is precisely what Shimano Synchro-Shift technology enables, always selecting the optimal next-higher or next-lower gear combination, regardless of whether this requires shifting at the rear derailleur and/or the front derailleur.

Shimano Synchro-Shift functions

• Full Synchro-Shift: The front derailleur reacts to the shifts the rider makes on the rear derailleur. Essentially, this means that only one shifter with two levers is needed to operate both the rear and front derailleurs.
• Semi Synchro-Shift: The rear derailleur responds to the gear changes the rider makes on the front derailleur. The rear derailleur automatically performs the necessary compensatory shifting.
