Description

The Fastest Ultegra Shifting To Date

Shimano Ultegra RD-R8150 12-Speed Rear Derailleur is more versatile than ever thanks to a single cage length option compatible with 11-28, 11-30, and 11-34 cassettes. It also packs the fastest, most precise shifting out there into a more affordable option.

This rear derailleur is updated with Shadow technology. Shadow tech is made with a low-profile design and single tension construction, so the derailleur does not hit the chainstay in rough riding conditions. The result is smooth and silent performance.

The Ultegra RD-R8150 12-Speed Rear Derailleur is also customizable via the Shimano E-Tube Project App, which allows you to personalize your bike, update firmware, and maintain it by connecting it wirelessly to your bike.

  • Compact design includes an integrated wireless unit, charger, switch
  • LED status indicator (Battery indicator, Pairing, Adjust mode etc.)

Upgrading to Di2 on my Trek Domane and these Shimano parts will be smooth like butter. Quality part at a great cost.

Charging cable sold separately. This cable is needed for the rear derailleur. Given the price of the derailleur, it should be included.
