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.

  • 58% faster than RD-R9150
  • Compact design includes an integrated wireless unit, charger, switch
  • LED status indicator (Battery indicator, Pairing, Adjust mode etc.)

RR-R8150 12-speed rear derailleur

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

Derailleur Replacement Front and Rear

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