This is a mix of Shimano Ultegra and 105 12-speed compenents to make the most cost effecient upgrade to your existing road bike with rim brakes.  With this kit we re-use what we can from the existing kit while upgrading everything necessary to convert to 12 speed.

Ideal for modernising a loved carbon or alloy frame with the latest tech.  This is a direct swap for 10 & 11 speed Di2 and we've successfully installed on old alloy frames that ran external gear systems.

Upgrade kit Includes:

  • Ultegra ST-R8150 STI 12-speed shifter set for rim brakes
  • 105 FD-R7150 Front Derailleur
  • 105 RD-R7150 Rear Derailleur
  • 105 FC-R7100 Front Crankset (assorted ratios & crank lengths)
  • 105 CS-R7100 12-Speed Cassette
  • 12-Speed Chain
  • Di2 Wiring Kit for Rim Brake
  • Di2 Battery
  • Di2 Charger

Roll over from existing groupset (Optional):

  • Front Rim Brake Caliper
  • Rear Rim Brake Caliper
  • Bottom Bracket

Note:  Bikes that are currently running 9 & 10-speed may need a new rear wheel to fit the 12-speed cassette.
