This is our Dura-Ace "lite" groupset for 12-speed.  We've kept the Dura-Ace components where it matters most and substituted for Ultegra R8170 to save a few dollars. This gives you an incredible groupset but your bike and wallet will be a fraction heavier.

What do we change and what do you lose?

Note:  The groupsets also have a different cosmetic finish.  Dura-Ace components are an emaculate gloss black while the Ultegra finish is a more subtle matt finish.

Description

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.

Shimano Dura-Ace CS-R9200 12 Speed Cassette 11-30

The uninterrupted shifting experience of the DURA-ACE R9200 12-speed cassette range lets you climb, sprint, and push your limits without stopping to think about your next gear change. Larger driving cogs maximize drivetrain efficiency and create compatibility with both SHIMANO 11 and 12-speed freehub bodies.

HYPERGLIDE+ cassettes have revolutionized off-road shifting with their seamless shifts both up and down the gear range. Now it's time for the technology to change road cycling. Even during maximal efforts up a climb or nearing the finish line, riders no longer need to back off to perform a shift. In any gear, DURA-ACE R9250 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing 11-speed freehub bodies. All this while increasing to 12-gears and without increasing weight, DURA-ACE CS-R9200 cassettes are the new paradigm in road shifting.

2x Shimano Dura-Ace Di2 ST-R9270 12 Speed Shifter w/ BR-R9270 Disc Brake Calipers

Disc Brake Caliper

With an all-new design, DURA-ACE BR-R9270 hydraulic calipers are the most compact yet. MONO-BODY construction ensures light weight and rigidity, proving that good things can come in small packages.

With an all-new MONO-BODY construction design, high performance braking has reached a new peak. The BR-R9270 caliper drops weight while also providing increased pad clearance, ensuring a quieter ride. Lastly, a new bleeding process makes maintenance easier than ever.

Levers

All-new lever ergonomics on the DURA-ACE ST-R9270 dual control levers bring new levels comfort and control to road cycling. With the fastest wireless shifting available and even more precise brake modulation, DURA-ACE redefines performance.

Now featuring SERVO WAVE ACTION brake technology, the new DURA-ACE ST-R9270 brake lever delivers modulation and control like never before. Wireless shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. All of this resides in a DUAL CONTROL LEVER to employs the most advanced materials to offer light weight and refined ergonomics that provide comfort and control for the most demanding conditions.

1x Shimano RT-MT900 Ice-Tech Centerlock Disc Rotor 160mm
1x Shimano RT-MT900 Ice-Tech Centerlock Disc Rotor 140mm

The pinnacle in mountain bike braking, SHIMANO XTR RT-MT900 disc brake rotors deliver superb stopping power for the most aggressive riding. The ICE TECHNOLOGIES FREEZA rotors dissipate heat to maintain braking performance on long downhill stretches. SHIMANO's CENTER LOCK mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.

Shimano Dura-Ace FC-R9200 12 Speed Crankset

DURA-ACE FC-R9200 crank, the heart of the bicycle, ensures that no portion of your pedal stroke is wasted. With hollow arms and chainrings, weight is kept to a minimum but stiffness and shifting precision is maximized.

The DURA-ACE FC-R9200 crank performs two vital functions: transferring your pedaling effort into the drivetrain and ensuring the fastest, most precise front shifting available. With HOLLOWTECH II crank arms to ensure light weight and Shimano's class-leading chainring designs, the FC-R9200 won't let you down. The FC-R9200 is offered in even shorter crank arms lengths to offer fit options for any rider.

Shimano Shimano Dura-Ace CN-M9100 12 Speed Chain

Designed for SHIMANO's revolutionary XTR M9100 12-speed MTB groupset, the M9100 chain provides enhanced chain retention thanks to an extended portion of the inner plate. The new chain features quick-link assembly and SIL-TEC treatment for extended offroad durability.

2x Shimano EW-SD300-I Electric Wires for Di2 12 Speed (900mm & 1200mm)

Electric Wire SD300 for Internal Routing

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.
