Hammerhead + Shimano Di2

Here at Hammerhead, we are committed to constantly improving in ways that benefit riders. With each update and integration, we chart an intentional path of continuous improvement.

Unfortunately, we don't always have the ability to supply every product integration we want for our riders. At the request of Shimano, effective with next Thursday’s software update on June 2nd, riders who utilized Di2 integration will lose access to a small subset of features. The update will remove on-screen battery status and shifter mode data, front and rear derailleur indications, and Karoo screen control via the Di2 hood buttons from Shimano Di2 drivetrains. 

Important note: all other Karoo 2 functionality will continue to work for Shimano riders, it is this small subset of Di2 features that Shimano has withdrawn permissions for until we are able to forge a new agreement.

We remain hopeful in pursuit of a new path to provide more software features to Shimano riders in the years ahead. For any questions or concerns, please reach out to us at support@hammerhead.io
