Liotto was imported into the US by Gene Portuesi of Cyclo Pedia/Complete Book of Bicycling (as an oft cited expert in that book)fame. He did this for a 2-3 year period around 1971 or 1972 (Beginning with his 10th eddition catalog).
They were spec'ed with or built up with full nuovo record group, a unica-nitor saddle. Not sure of stem/rims/spokes but likely 3TTT record, Fiamme, Rebergel stainless. Modest chrome: the fork crown, 1/4 of the forks/stays.
Columbus tubing - bland colors I recall a solid blue and solid red. A "Liotto" graphic on the down tube, columbus tubing decal on the seat tube. I think the head tube graphic was a cyclo-pedia/Cycle Sport Shop (the name of his retail store) type decal but might alternatively be an "L."
The head angle was 74 degrees. An acquaintance of mine let me test ride his Liotto in 1974. I did a 2 mile test ride on a flat area. I can report is that the brakes worked wonderfully and that it didn't flex too much in the bottom bracker area while beginning a sprint effort.
Nice bikes. Gene was marketing them after his source for Louison Bobet (Mercier?) stopped. He also sold a entry racer brand called Doneselli. He also included a flyer in his catalog for a new american made frame called "Matthews" built by Matt Assenmacher.
Liotto is still going strong in Italy.
Mojo factor: Who knows. It seems like stuff brought into the midwest, regardless of overall quality, seems to get ignored. Liotto was better built than the predecessor Bobets and Rochet, the graphics were simpler, though.
