OK, my new Specialized Rockhopper has shock absorbers in the front. In trying to transfer my computer from my Hardrock to the Rockhopper, I find that

1. Placing the magnetic pickup on the shock absorber would make it way far away from the magnet on the spoke; and

2. Of course, the diameter of the shock is far larger than the diameter of my front fork on the Hardrock, so even if I could mount it there it would take a very long ziptie to do it.

I suppose I could mount it on the rear wheel - but there must be a more elegant solution.

BTW, I now have the rack, frame pump, kickstand, bell, panniers, wedge mounted safely and securely, and will be doing the bar ends today. The lights are a problem because of the increased diameters of the bars. My light mounts do not have that big of an adjustment and strap length available.
