Shimano Forces Hammerhead to Remove All Di2 Related Functionality From Karoo

May 26, 2022

Effective next Thursday, Hammerhead will remove all Di2 functionality from the Hammerhead Karoo series, via firmware update. This is at the request/demand of Shimano, who according to Hammerhead, now sees them as a competitor. This means all Di2-related functionality including Di2 battery status, gear indicators, page changes via Di2 hood buttons, and shifter mode, will all be removed. DC Rainmaker
