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 for external components, includes the charging port, and replaces the previous SM-BCR2 charger. The rear derailleur also houses the transmitter for 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 knob, 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 second shifter can 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 Dura-Ace BR R9200 / BR B9210 rim brakes:

The elegantly designed rim brakes of the R9200 series, with their lightweight two-pivot caliper, offer maximum precision for better control and greater reliability in racing. Thanks to the additional reinforcement booster, the Dura Ace BR R9200 brakes offer unprecedented torsional stiffness. The rim brake is easy to adjust and maintain thanks to easy access to tools and the ability to change wheels quickly.

Shimano Dura Ace FC R9200 crankset:

For the new Dura Ace 12-speed drivetrain, Shimano relies on proven gear ratios with large sprockets and chainrings. The advantages include large chain wrap angles, which guarantee quiet and highly efficient power transmission and allow for finely graduated cassettes. The new 12-speed cassettes are also compatible with the older HG11 freehub bodies. Hollow-forged chainrings made from aluminium and carbon fibre-reinforced plastic, thin-walled hollow-forged crank arms and a reduction in the outer surface area reduce the weight of the new Dura Ace 12-speed FCR 9200 crankset. The design of the 2x11-speed Hollowtech II crankset ensures enhanced performance. As a key component in Shimano’s new 12-speed Dura-Ace series, the FC-R9200 crankset is characterised by Shimano’s signature shifting quality and power transfer efficiency. Redesigned for seamless 12-speed shifting, the Dura Ace crankset is available in lengths from 160 to 177.5 mm. This means greater performance and improved customisation options for smaller riders, triathletes and riders with specific biomechanical requirements.

Optional bottom bracket:

We offer optional bottom brackets from Shimano, Wheels Manufacturing and FSA for the Shimano Dura Ace Di2 groupset. This allows the crankset to be fitted to all standard bottom bracket shells.

Shimano Dura-Ace CS-R9200 cassette:

The Shimano Dura Ace CSR9200 cassette, featuring two large sprocket blocks and titanium sprockets on an aluminium spider, delivers Shimano’s outstanding smooth shifting performance combined with low weight and long-lasting durability. Shimano offers replacement sprockets for these cassettes. This means that if only a few are worn, they can be replaced cost-effectively.

The new Hyperglide+ cassettes set new standards for shifting, thanks to smooth gear changes across the entire gear range. Even when applying maximum force on climbs or sprinting to the finish line, riders no longer need to worry about changing gears. In all gears, the Dura-Ace R9200 drivetrain ensures maximum efficiency thanks to larger teeth. Despite their expansion to 12 speeds without adding weight, Dura-Ace CS-R9200 cassettes set new standards for road bike shifting systems.

The 12-speed cassettes are compatible with both the new HG12 and the previous HG11 freehub bodies. The new 12-speed freehub bodies feature finer teeth. This allows for a significantly better connection between the cassette and the freehub body.

Shimano Dura Ace CN - M9100 chain:

The Shimano chain for 12-speed road bike and MTB drivetrains. The special asymmetrical outer and inner links, combined with Shimano’s SIL-TEC surface coating, minimise friction, optimise performance and also reduce dirt build-up.

The chain is perfectly matched to the 12-speed Shimano chainrings with Dynamic Chain Engagement+ (DCE+) tooth profiles. The HG Plus chain has been completely redesigned and features even finer, precision-machined contact surfaces with the sprockets and chainrings, particularly on the inner links. Furthermore, the inner links are chrome-plated, making them even more durable whilst delivering excellent shifting performance when shifting up or down.

Synchro-Shift Technology

Synchro-Shift technology greatly simplifies shifting and significantly reduces the number of decision-making processes that take place whilst riding. Particularly in crucial race situations or when riding at the limit, riders often have to navigate a multitude of decision-making processes 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 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.

Shimano Di2 Rim Brake Installation:

Installing Shimano Di2 components is almost easier than fitting traditional gear systems. The standardised cable connectors and the junction box ensure straightforward and quick installation. The shift levers are connected to the Junction Port EW-JC304.

Unlike the disc brake version, the Di2 12-speed STI shifters for rim brakes are not wireless and require the EW-JC304 junction port for cabling. This provides 4 connectors to link the EW-SD300 cables to the battery. A total of 5 cables are required: 2 cables, approx. 60 cm long, from the STI to the Junction Port, and 1 cable, approx. 140 cm long, from the Junction Port to the battery. Due to its small size, the junction port can be easily stowed in the down tube of the frame without any additional mounting aids. In addition, a power supply cable of 120 cm for the rear derailleur and 60 cm for the front derailleur is required.

Compatible bottom bracket shells

There is now a wide variety of bottom bracket shells available on modern frames. Shimano only offers compatible bottom brackets for some of these. To ensure the Ultegra groupset fits all frames, we supply optional FSA or Wheels MFG bottom brackets for the bottom bracket shells for which Shimano does not offer bottom brackets. Wheels Outboard bottom brackets are significantly more durable than standard press-fit bearings, as the cup halves are bolted together, ensuring they sit flat and securely within the frame. Wheels bearings are available in various quality grades: ABEC3 standard bearings, angular contact bearings and ceramic bearings.
