Aerodynamic modifications:
-Custom-built wood/fiberglass/epoxy resin/aluminum chainstay:
This made the bike very comfortable for me and raised the bottom bracket enough to seriously improve aerodynamics.
-Homebuilt rear wheel covers:
The first prototype covers were cardboard and both the speed and high-speed stability were improved.
These wheel covers are the third set, made of 1/4" foam insulation board, are very light but not really very durable.
-Homebuilt massively reclined seat/neckrest:
This photo was taken after its first outing. The seat pan has since been faired, padded, the seat trimmed away from my legs and the neckrest modified.
On its first ride, I caught a P38 recumbent bicycle after a short, high-speed pursuit and left it when I passed it going uphill.
My low Sofrider seatback is at a lower/shallower angle than is the stock Vendetta seat and is the reason that my Sofrider flies on the flats.
-Five-dollar used road bike drop bar:
This put my arms where I like them... straight out in front of my shoulders.
Power, control, and comfort!
-Over the years, I have tested and removed little fairings on the fork legs, main frame tube, and the rear triangle:
The small improvements in the bicycles' aerodynamics were just noticable, but not good enough for me to want to seriously make any attempt
to make them permanent.
The chainstay and seat made huge differences and were totally worth the effort.
This Sofrider is both extremely comfortable and Vendetta-fast on the flats.
The modified Sofrider convinced me that what my body really was crying out for was a Vendetta.
A nice used V 1.5 became my new road bike a few years ago.

I replaced the stock seat for a home built composite seat that is lighter than stock and fits me like a used glove.
See how similar the seating position is on both the Sofrider and the Vendetta?
