OK. I think I found a solution to this dilemma. A 4 hr drive home leaves one with time to think...here goes..

Go to your local hobby shop and purchase the following....

1. A strip of .062 music wire
2. A strip of .055 music wire

Note: due to variances in manufacturing of the bike, purchase different diameters. The ones above was what I had in my workshop at home. They're like $1.50 for a 36" length where I'm at (Michigan, USA).

Cut a piece of each (I'm still experimenting on the length - see below). Once cut place one strip on one side of the screw and the other on the otherside of the screw. Basically your going to use both strips to take up the space between the anti-rotation screw and the groove on the handlebar post. Don't choose diamters that are so big they get stuck. You want a tiny bit of play so you can still raise and lower the handlebar post like it's suppose to. That's it.

With this method, you do not need to sand off the anodizing, add anti-slip compound, or install a new quick release clamp. You can make the strips of wire longer, and use a rubber band to prevent them from falling out. They just need to be short enough to allow the handlebars to go down all the way. When tipped upside down the wires will fall onto the head of the handlebar quick release, and the rubber band will keep them in the groove (haven't done this yet myself). Good luck. I'll post some pics when I get a chance.

Time for Mod:
Getting the stuff: 30min -1 hr (longer if you browse the hobby shop)
Cutting: 60 seconds if you've got a Dremel
Install: 2 minutes for the first try. 15 seconds the final try if you hold your breadth and keep from blinking.
