I own 2 Columbus Aelle frames.
One is a Paletti (circa early 80's) which I rode as my lousy weather training bike. Obviously it was a bit heavier then my SL bikes, but was a relatively nice rider nonetheless. I'm actually debating whether to re-build this or try & pick-up an SL frame from the 70's to re-build with my spare Campy grouppo.
My other Aelle frame is a Saronni (circa late 80's). Interestingly, the 3 main tubes are "crimped" (for lack of a better word...I can't remember what the correct name of this was called) like a corrugated box, which if I recall was supposed to add stiffness. This frame I never liked. Felt heavy & dead. Frame has an interesting red fading to silver chrome finish.
