What to do with gaspipe? Ride the wheels off it.
My gaspipe Super Grand Prix, Super comfy although I'll readily admit it's much more flexible than my 531 Comp GS so I do lose some power through frame flex.
My wifes gaspipe Bottecchia, an old guy on a modern road bike was drooling over it at a coffee shop this morning. Told us it was probably worth $1000, I didn't have the heart to explain the value to him.
