Shimano Dura Ace R9270 12 Speed Di2 TT Disc Groupset Kit

Shimano Dura-Ace Di2 FD-R9250 12 Speed Front Derailleur

Despite its smaller, lighter design, the DURA-ACE FD-R9250 brings the fastest front shifting on the market.

The fastest just got faster thanks to the DURA-ACE FD-R9250. Tipping the scales under 100 grams, the new design shifts 45% quicker than Shimano's FD-R9150, already the fastest on the market. The frontal area of the FD-R9250 is also reduced decreasing aerodynamic drag.

Shimano Dura-Ace Di2 RD-R9250 12 Speed Rear Derailleur

The fastest ever shifting across SHIMANO's widest ever DURA-ACE gear range, the RD-R9250 is capable of both race wins and personal bests.

The DURA-ACE RD-R9250 integrates the system charging port and a wireless connectivity unit all while delivering super fast, precise shifting worth of any podium. A single cage length shifts cassettes from 11-28 to 11-34 bringing new versatility to the world's best road component group.

2x Shimano Dura Ace Di2 ST-R9270 STI brake/shift lever

The electronic Shimano Dura Ace Di2 ST-9180 Dual Control lever is especially suitable for Time Trial and Triathlon handlebars. The STI lever not only offers different grip positions, it also allows the hand to remain on the brake lever to trigger the shifting process. This is possible because of the Synchro-Shift mode which makes just one button on each shift/brake lever sufficient to operate rear and front derailleur. The system decides which of the two components is used to change gears. For individual adaptation, the brake lever also features the option of reach adjustment.

BR-R9270 disc brake caliper

Its one-piece Mono-Body design not only makes the Shimano Dura Ace BR-R9270 brake caliper incredibly light, but also gives it outstanding stiffness values. At the same time, the Flatmount brake made from a single, cold-forged aluminium block proves that high performance is also possible with compact dimensions.

A 10 % increase in brake pad spacing also allows for a significant reduction in noise during braking. In addition, when the RT-MT900 brake disc rotor (sold separately) is used, its deformation-resistant design, even with increasing heat, helps to create an extremely quiet and smooth braking system.

To simplify maintenance, the hydraulic 2-piston brake caliper not only features the proven One-Way-Bleeding system, but also a separate arrangement of bleed nipple and opening screw. On the one hand, this minimises the risk of the bleed kit hose slipping off when opening or closing the system and, on the other hand, makes it unnecessary to dismantle the caliper from the frame for bleeding process.

DI2 Remote Triathlon Shifter 

With a refined ergonomic shape and simple, single-button design, the SW-R9160 DI2 remote triathlon shifter provides quick shifting while riding in the aerobars. Utilizing SHIMANO SYNCHRONIZED SHIFT program, each bar end shifter can be programmed to upshift or downshift the rear derailleur while the Di2 computer decides when to shift the front derailleur for the optimal front and rear gear combination.

Shimano BT-DN300 Internal Battery 12 Speed

The new DN300 battery features the same waterproof design that Di2 users have loved for generations. Now with 3 ports, it delivers stable power to Shimano's 12-speed road derailleurs and shifters (if a fully wired option is selected).

With the same size as its predecessor, the slim DN300 battery can be housed inside seat posts or frames ensuring a clean aesthetic. Now with 3 ports, the DN300 simplifies wiring to front and rear derailleurs, supplying stable power at all times. The third port is for riders who seek the redundancy of Shimano's 12-speed Di2 wired option.

Shimano EW-EC300 Charging Cable 12 Speed

The new EC300 charging connector is designed specifically for Shimano's 12-speed Di2 road drivetrains. Connected via the rear derailleur, it is also compatible with Shimano power meters.

Charging of the new Shimano 12-speed Di2 road drivetrains is now accomplished with the EC300 charger cord. Attached to the rear derailleur, this new cord is less expensive than previous chargers and can also be used to charge Shimano power meters.
