Shimano 105 R7150 Di2 12-Speed Rim Brake upgrade kit

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.
