This Rossin has never been ridden or even built up, as it is new old stock. I bought it from a bike shop when they were closing out some of their Rossin line of framesets.
This beautiful fully-lugged Rossin measures 54cm from the center of the bottom bracket to the center of the seat tube, with a 55cm top tube. The frame has a canary yellow to inkwell blue paint scheme with contrasting decals on the down tube and seat tube. The 1" threaded fork is a matching yellow with chromed lower legs. The right chain stay is also chromed.
The tubing is Columbus Neuron, one of the finest steels offered by Columbus and designed exclusively for bicycle frames. Neuron tubing is one of the tubesets in the Columbus Nivacrom steel family. Columbus Nivacrom gets its strength not from heat-treatment, but from special composition. Niobium and vanadium are alloyed with the other elements to produce a high strength and dependable steel. The high end Columbus tubesets are all made of this same material, with different shapes and butting profiles. Makes for a strong, yet light, steel frameset.
There are two sets of water bottle bosses, a braze-on front derailleur tab, down tube shifter bosses, and the rear brake cable is internally routed through the top tube. The rear dropouts are semi-vertical with adjusting screws included. The rear spacing on the dropouts is 130mm, the head tube is 136mm in length, and the 1" threaded fork steerer tube measures 182mm.
The frame is fully lugged, with the Rossin "R" cut out of the lower head tube lug. The head tube lugs also have a curl on part of them, making for a very nice fancy touch. Decal on the bottom of the seat tube says "Handmade by Rossin Italy The Dupont System".
This bike was new old stock with a very few very small paint chips that have been touched up. I cleaned up the bottom bracket shell and an Italian bottom bracket spins right in.
$450 professionally packed and shipped and insured to the lower 48 United States.
