Hammerhead Mounting System (Patent Pending)

  • A new mount for a new era - Hammerhead reimagined the cycling mounting system from first principles to create a new standard that is reliable, easy to use, elegant, and aerodynamic. It is also backwards compatible with standard Quarter Turn designs. The result is the patent pending Hammerhead Mounting System (patent pending).
  • The Karoo to Quarter-Turn Adapter allows you to put the Karoo 2 on any Garmin-compatible bracket, making Karoo 2 backwards compatible.
  • Aerodynamic profile - The low profile Hammerhead Mounting System (patent pending) is elegant and aerodynamic.
  • High contact area - The Hammerhead Mounting System (patent pending) presents a far greater contact area between the head unit and mount making it intrinsically stronger than a quarter turn design. Its teardrop shape looks elegant on your bike when your Karoo 2 isn’t mounted.
  • Simple actuation - Karoo 2 slides into the Karoo Mount with an affirmative click. This allows it to be closer to the stem and easier to mount in tight spaces. It disconnects through rotation that requires overcoming two points of friction to prevent unwanted dismounting.
