I got some more pics last night with a friend's phone:

Rear view:

Angle view:

I'm going to source material for a windshield today. The roof piece and turtle deck piece are finished but not yet installed. I'm also going to install the sealing tabs on the mid-section piece so that there are no gaps for the air to penetrate on the sides, reducing drag further.

It's much faster than I thought it would be, but I don't yet have a torque sensor or objective way of measuring power requirements to figure out CdA, Crr, and drivetrain losses. The goal is a CdA of 0.15 m^2 or less. I don't think it's there yet, but it will probably get there.

Note the new rims. The KMX rims kept breaking spokes. On Monday I had a local bikeshop lace some Velocity rims to the proprietary KMX hubs. It brakes much more straight now since hard braking kept destroying spokes on the stock KMX rims resulting in me having to make frequent adjustments.

The wheel discs will go back on the rims after I have them checked out and adjusted by the bike shop next week.
