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.

Combining Shimano's new Di2 platform and the road incarnation of HyperGlide+, the Ultegra R8150 front derailleur shifts between chainrings with the fastest, most seamless action on the market.

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.

Shimano Ultegra CS-R8100 12 Speed Cassette 11-30

The uninterrupted shifting experience of the Ultegra R8100 12-speed cassette range lets you climb, sprint, or cruise without stopping to think about your next gear change. Larger driving cogs maximise drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed Freehub bodies.

HyperGlide+ cassettes revolutionised off-road shifting with its 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 racing a friend, riders no longer need to back off to perform a shift. In any gear, Shimano Ultegra R8150 drivetrains maximise efficiency thanks to larger cogs and retain compatibility with existing HyperGlide Freehub bodies. All this while increasing to 12-gears, Ultegra CS-R8100 cassettes are the new paradigm in road shifting.

To the delight of riders and mechanics alike, the new Ultegra BR-R8170 caliper delivers enhanced modulation, a quieter brake system, and an easier than ever bleed process.

The Ultegra R8170 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.

Levers

Road riding has never been this much fun. That's because the redesigned Ultegra ST-R8170 Dual Control Levers have all-new ergonomics, even more precise brake modulation, and wireless electronic shifting. This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner.

Shimano's new Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven Servo Wave technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering the world's fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better.

Ultegra's new FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. Spanning 160 to 175 mm in length, Ultegra cranks now cater to smaller riders, triathletes, and cyclists curious about shorter crank arms.

An integral part of Shimano's new 12-speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-speed shifting, the Ultegra crank is now offered in lengths from 160 to 175 mm, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements.

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.
