Here are the results:

The PA10 is the lightest at 23.61 lbs. The tubular wheels are very light and it has only five speeds. Maybe Carbolite 103 isn't such bad stuff? I'll never call it gaspipe again.

The PX10 weighs 24.29 lbs. How did it get there from the claimed weight of 21.5? The wheels are clinchers with wire bead tires. With the exception of the seatpost, I think all of the I think all of the Italian components are a little heavier than the French ones they replaced. The T.A. pedals are heavier than the Lyotards were. The Brooks saddle is definitely heavier than the plastic Ideale 2001. There's also all that clearcoat.

The Carlton weighs 25.57 lbs. Sure, the hub weighs over 2 lbs, but there's no derailers, no freewheel and just one chainring. The frame is double butted Reynolds 531. I could knock off some more weight with a lighter saddle and seatpost, but I like it the way it is.

I've still got a Fuji Mixte, a Bridgestone MB2 and a Gitane Tour de France to weigh and I'll post them this weekend.
