A 21 pound racer with eyelets for racks is a Sport Tourer in my book, and a great vehicle for a fast commute. I have not tried profile aero handlebars where you lay forward on your forearms - but my understanding is they are easier on the back as you are better supported on your forearms, but get neck strain from looking up. The neck strain can be helped by a higher stem, but that reduces the aero properties.
Enjoy the best, and survive the worst.

I use a GPS instead of a bike computer so I don't have a magnet. Could be the spokes though. There is one sensor I have trouble setting off but I think that is mostly as you can't see the line to park over as they paved over it recently. I thought the induction circuits worked like a theramin. I can make a theramin work but I am not necessarily magnetic. Even aluminim transmits electricity. Course I am probably just talking about stuff I don't understand.
The aero-bars made it worse as the injurey was in my lower back. My average speed has jumped several miles an hour and I am able to push as hard as I want without backpain which was something I couldn't do for more than 20 minutes before (got real annoying on long hills and long rides) going to the recumbent. From the first ride it was night and day for me. Don't think it is everyones solution but it was for me.
