Description

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.

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.
