New HED 3 Clincher & Disc Wheel Cover Ordered

1. No
2. &3. Depends on your pump head
4. Yes, or you can buy a kit from Cateye.
5. The valve stem opening on the HED goes on the right (drivetrain) side.

Yes you should buy a crack pipe and smoke it religiously.

By smoke it religiously, I mean I have no idea if that is some bike term I have never heard of. 

If you can find a smaller pump head go with it.  Crack pipes work but are just another piece of equipment you have to rely on that can possibly get lost.

I did put some tape over the serial #'s engraved on the inside of my Hed#.  They seemed a little rough and I just didn't want to take the chances on the tube.

You might have to adjust the position of the sensor on the fork so it will be close enough to "see" the magnet on the straight spokes of the HED.  Near the hub the narrow HED is a lot farther away from the fork than the dished or angled spokes of a conventional wheel.

I wanted mine to work with either my conventional Shimano spoked wheel or my HED, so I had to move the sensor up the fork where the angle of the fork brought it closer to both wheels.  Didn't glue it on until I found a position that worked for both wheels.
