Shimano Ultegra Di2 FD-R8150 12 Speed Front Derailleur

More compact and faster than ever, the Ultegra R8150 front derailleur performs digitally precise front shifts under any circumstances.

Shimano Ultegra Di2 RD-R8150 12 Speed Rear Derailleur

Now simplified with a single derailleur cage length, the new 12-speed Shimano Ultegra R8150 rear derailleur packs the fastest, most precise shifting on the market into a more affordable option.

With the fastest, most accurate shifting on the market, the new 12-speed Ultegra R8150 rear derailleur is more versatile than ever thanks to a single cage length option compatible with 11-28, 11-30, and 11-34 cassettes.

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.
