Time Trial and Triathlon Gear Upgrade Kit Shimano Dura Ace 12-speed Di2 R9250

The Dura Ace Di2 12x2-speed component groupset for time trial and triathlon use and rim brakes. Optionally available with handlebar-end shifters and charger. The ST-R9160 shifters are not wireless and are wired to the battery in the traditional manner. To function with the 12x2-speed rear derailleur and front derailleur, this combination requires the latest firmware version. You can install this via the Di2 app. We also offer the firmware update as an option.

The components used by the pros: the high-end Dura-Ace wireless 12-speed series, crafted from the finest materials – titanium, carbon and aluminium. As a complete package, the Shimano Dura Ace R9200 Di2 TT time trial groupset, optionally with charger and handlebar-end shift levers. The new Shimano Dura Ace Di2 R9200 series components, the high-end version of Shimano’s electronic road bike components.

Shimano does not manufacture 12-speed time trial shifters. Therefore, the Dura Ace ST-R9180 and SW-R9180 Di2 shifters are used and are then fitted complete with Di1 cables. To ensure the shift levers work with the 12-speed components, all Di2 components must receive the latest firmware update. This can be done after assembly using the Shimano app and a mobile phone, tablet, PC or the SMPCE02B diagnostic device. We also offer this update as an optional service.

Shimano Dura-Ace RD-R9250 Di2 rear derailleur:

The new Dura-Ace Di2 rear derailleur is the centrepiece of the new Di2 12-speed components. It provides the wireless functionality and connection to external components, and also includes the charging port, replacing the previous SM-BCR2 charger. Furthermore, the rear derailleur houses the transmitter for wireless communication with the STI shifters and other external devices, including those from third-party manufacturers. It also 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 Dura Ace Di2 RD R9250 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 link to the motor in the event of strong external forces to prevent damage.

Shimano Dura Ace FD-R9250 Di2 front derailleur:

Lighter, faster and more aerodynamic: the Dura-Ace 12-speed Di2 front derailleur. Designed for chainring sizes ranging from 50/34 to 54/40 teeth, the new 12-speed Dura-Ace Di2 front derailleur operates even faster and more precisely. More compact and faster than ever before, the Dura Ace R9250 front derailleur delivers shifting with digital precision in all conditions. By combining Shimano’s new Di2 platform with the road bike version of Hyperglide+, the Dura Ace R9250 front derailleur shifts between chainrings as quickly and seamlessly as no other model on the market.

Shimano Dura Ace Di2 STI ST-R9160 TT Shift-Brake Lever:

With the ST-R9160 STI Disc shift-brake lever, Shimano introduces a highly compact shift-brake lever for time trial handlebars, designed for rim brakes and the electronic Di2 shifting systems, marking another milestone for road cycling. The new Dura Ace Di2 STI levers offer optimal ergonomics thanks to their adjustable grip width and are fitted with carbon brake levers. Shifting is extremely fast and precise. Thanks to electronic transmission of shift commands, these are executed without delay. Operation is similar to that of mechanical STI levers; shifting occurs at the touch of a button. The Di2 shift levers are equipped with the programmable Multishift function. The grip width adjustment allows the Dual Control shift/brake levers to be optimally adapted to the rider and makes them very well suited for riders with small hands. Shifting is significantly faster with the new shift levers. This is achieved through a 20 per cent shorter cable pull. The grips feature an ergonomic design for greater comfort – even over long distances.

Shimano Dura Ace 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

Synchro-Shift technology

Synchro-Shift technology greatly simplifies shifting and significantly reduces the number of decisions that need to be made whilst riding. Particularly in crucial race situations or when riding at full throttle, riders often have to make a multitude of decisions alongside the physical strain, which are frequently disrupted and lead to wrong decisions. 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 on 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.

Shimano Di2 installation:

Installing Shimano Di2 components is almost easier than fitting traditional gear systems. The standardised cable connections and the junction box ensure straightforward and quick installation. The shift levers are connected to Junction Port A on the junction box; a cable runs from Junction Port A to the EW-AD305 connector, and from there the cables run to the battery.The rear derailleur and front derailleur are also connected to the battery. The battery can be mounted externally on the bottle cage or internally in the seat tube or down tube. Frames specifically designed for this purpose are required for internal cable routing.
