I just recently bought this new old stock rossin frame and can’t seem to find any information or a pic of another one similar online ? Does anyone know which model is it? Year? Or anything about it? Nothing written on the lugs, no number or logo engraved underneath it ? Any info would be amazing

    In terms of 'which model' - it didn't really work like that back then. Builders mainly just built frames from tube/lug sets and painted them to customer spec, or to certain patterns if they were producing a run.

    Columbus Aelle is relatively low-end tubing (nothing wrong with it at all) and the paintjob and sloping fork crown puts it late 80s, early 90s, IMO. Geometry looks race oriented, rather than touring. Good looking bike - just enjoy riding it and don't fret the provenance, as without any other distinguishing marks or numbers you will probably never know for certain.

    I can remember Rossin frames being sold in the U.K. in the late 1980s through the Freewheel (Madison) catalogue which was the cyclists' bible in those days. Their main attraction, compared to most other frames around, was their very fancy paint jobs. And of course their Italian name.

    The OP's bike is clearly racing geometry with horizontal rear dropouts, which don't appear to have any adjustment screws, nice lugs with heart-shaped cutouts (quite common at that time) and an attractive engraved sloping fork crown. The seat stays are shot in to the seat lug, a technique which gives very little brazing area compared with top plate or top eye stays and so is only really strong enough for a racing bike rather than a tourer. Looking closely at the seat lug there appears to be a bit of bubbling - don't know if it's in the paint or scruffy brazing.

    The down tube label suggests it is a full Columbus Aelle frame. This was a straight gauge (non-butted), Cro-Mo steel tube set claimed by Columbus to be suitable for amateur racing and touring use. It was not as strong or light as better quality butted tubing such as Reynolds 531 Mn-Mo which had a tensile strength of 802 N/mm2 compared with Aelle's figure of 720. But Aelle is still perfectly acceptable, if not top end, tubing.
