I'm reasonably happy with the Blackburn computer I have, but I never liked how it had to be mounted on the bar to the right or left of the stem. I like symmetry. I also like tucking into a more aero position sometimes, but the computer obstructed my left hand.

Until now. I had the mount for an old computer sitting around, so I put it on my bar. I then took the caps from two cartons of Tropicana juice, drilled a hole into the center of each of them, positioned them rim to rim, and bolted them to the mount and to each other. The Blackburn unit fit nicely with the help of a homemade shim (old tube).

Now my computer is directly centered to my stem, and is out of the way. Clever, innit?
