RIDER987

Hi everyone,

I'm hoping someone can help me to identify this Rossin model and value.

From my research it looks like a 80s Rossin Record but some things don't match up.

I'm thinking it wasn't built up until early 90s due to the parts? (Mix of Shimano and Campag)

It also has a 27.0 Sakae seatpost so it's either the wrong size or it's not a SL Rossin Record.

Thoughts?

Your bike has the Campagnolo Portacatena dropout, introduced in 1977 and used until the inventory ran out. Might be as late as very early 80's...

Parts-bin built by someone so they could sell it. Someone who likely tightened the seat lug too tight so the 27.0 post would "fit."

Worth more IMHO as a rider in current shape given frame condition and marginal part resale values. Frame maybe $200 as is, whole thing maybe $400...?

The experienced resellers will be along shortly to further hone these guesstimates...

That does make sense especially after I googled that drop out.

On this page there seem to be 2 Rossins that look to be the same frame?

Both also have the same front derailleur so that's another clue..

Many (but not all) portacatena-equipped frames were of the level to wear a Campagnolo SR front changer.
That one is the three-hole version made from 1979 to the mid-80's. It could be (but is not guaranteed) original to the bike.
Is the bottom bracket Shimano or Campagnolo? Many flippers don't pull them if they spin without grinding noises.

I'm not sure whether it's Shimano or Campagnolo but it's definitely not original as it looks to be a sealed bottom bracket.

The previous owner had it for at least 25 years so I don't think he was the flipper. It actually looks much nicer in person then the photos suggest.

Portacatena dropouts in conjunction with a front derailleur braze-on suggests circa 1982-1984. These features suggest a Columbus SL frame so check for a 27.2mm seat post and a fork steerer tube with the Columbus dove logo and five helical ridges inside, at the bottom.
