This Hammerhead A1 handlebar mount for the Karoo offers something you don't often see in bike computer mounts: it's adjustable! I bought it for my second bike, so now I don't have to constantly remove and install the mount on the other bike.

Seems very robust, fits well, holds Hammerhead well. I like that if my Hammerhead 3 is not fully clipped in, the orientation is rotated. I have two fo these (for two bikes, obv, I'm not THAT happy about it).
