ps It's great to speak some Mezzo upgrading.

Questions for you;
1. why did you choose not to use the rack mount for your rear light instead?
2.is that a cordless computer? What make is it?
3. do the rollerblade wheels get in the way of sliding the Mezzo bag on? whats the spacer made from?
4. Ever thought of puting a wheel on the front mudguard instead of a foot?

thanks[/QUOTE]

Answers:
1. Couldn't see how to do it without interfering with parking position of the bike and/or the mounting of the Mezzo bag.
2. No it is a cheap cat-eye speedometer. There is just enough wire to not interfere with the fold.
3. The wheels don't interfere with the mounting of the bag at all. The spacer is a standard plastic spacer found in the screw bins of my local hardware store. The wheel bearings fit perfectly on the
1/4" x 2 1/2" bolts from the same bins.
4. The wheel on the mudguard is a good idea, but it would require a bit more engineering and may not work after all that effort. It was simple just to cut off a piece of PVC pipe, and it slips right on over the foot, and is held there by friction.

I tried folding the bike without using the clamp using your method. I can see that it won't work for me.
The front wheel drops and negates the wheeling aspect of the fold. Now I'm having second thoughts. I'm going to research whether an sram I motion 9 will work, or a Rohloff. Problem the I-motion 9 comes with 36 holes. That's a lot of spokes for a 16" wheel that looks crowded now with 28 spokes.
Do you think either of these will create the same problem with the clamp? Having never seen the sram dual drive hub, I can not picture what it is that causes the problem with the clamp. Is it the derailler, the cable, or what?
