Hi peeps,
Just owned a Rossin recently but unsure on its authenticity.
Usually Rossin bikes have couple of Rossin's marking such as head tube lug, "R" panto on head lug, Rossin emboss logo on seats lug, logo panto on fork and so on such as :

But mine only appears on fork. Decals are under a layer of clear coat and tubing by Columbus Thron.

Hoping Rossin fans or enthusiasts out there could help to verify its legitimacy.

Thanks and cheers!

Will upload more detail pics soon. Thanks for your patience.

Why would someone fake a Thron tubed bike?

Thron tubing came out in the 90's and was relativly low on the columbus hierarchy, I wouldnt be at all suprized if this bike didnt have all the more intricate design details found on a Rossin from the 1980's.

And as OGF states, "Why would someone fake a Thron tubed bike?"

I think the rear brake bridge looks 'Rossin' too. Head tube lugs don't look like the usual 'Rossin' lugs though - perhaps a lower end lug? The paintjob looks to be in perfect condition and the frame has the Dupont decal - I would love to have a look at the front and rear dropouts to see if there is any 'damage' or indications that the quick release has been used sparingly to match the great state of the paint job or if the quick release has been used quite a bit indicating that the paint job may be new.

Looks fantastic. I did see a fake Rosin on ebay. Yours looks real.

Can you do a picture of the area where the seat stays join the seat tube? That's looking a bit different from what I'm used to, but, as I'm learning, that doesn't necessarily mean it's a fake.

And yeah, I'm also verging on the real. Take a shot of the underside of the bottom bracket while you're at it.

Noted. I will attached more pics as soon as possible.

Hi guys,

Attached here are the detail pics of my Rossin. Would be great to have more input on its authenticity.
p.s : hope pics are clear enough to view.

It certainly looks like a real Rossin to me.

I've got one also, without the usual Rossin-hallmarks except a panthographed fork. After lots of searching around for info, I came to the conclusion that not all Rossins have, for instance, a cut-out 'R' bottom bracket, the particular lugs and their name below the seatstay.

The earlier models (late 70's/ early 80's) certainly have those details, as well as the higher models after that period. But in the mid to late eighties, Rossin seems to have 'commissioned' quite some frames without those hallmarks. Usually it's on the mid to lower-end models; some of them might be even built for them, not by them per se. (But that was not that uncommon in that era, I've come to learn.)

Anyway, just my two cents: I wouldn't worry to much about it. It certainly doesn't resemble anything remotely suspicious (like some of the obviously fake frames with bad paintjobs and slapped-on Rossin decals, which is partly responsible for the general confusion, I think.)

I think it's a really cool frame by the way. Fantastic paintjob!

Looks fine.

I agree with Hum 3, your frame looks like new, old stock and well built and well painted. I suppose when building an 'economical' frame the construction and integrity of the frame is far more important than using fancy aesthetic flourishes such as expensive pantographed and branded parts. I think it is really important, for a respected bike manufacturer, to produce frames that live up to the company's reputation whether an 'economical' model or a 'top of the line' model.

I would ride that frame with pride.

Thanks Hum3;Michael Angelo; Gary Foundation for you comments and inputs. Even just a "lower end" Rossin but a least still a Rossin. Personally thinks is hard to spot on a Rossin due to uncertain design trademarks unlike Merckxes, Colnagos and etc which create doubt on its authenticity. Hoping in the future, I could own a "true" Rossin; RLX 5775 Competition or RL Sante'. For this current one, I'll just go with Campagnolo Chorus instead of C-Record. Cheers!

I'll definitely concur with your opinion. It's definitely not a mid/late-80's frame, and while I've not actually handled one of the mid-priced line (yet - give me time) I've run across enough of them in this forum to start learning about them. Lugs look good, and most everything else seems to fit. I'll be curious to hear a ride report on the frame, see how it stacks up against the high-line frames.

Give you a hint: Shimano 600 Tricolor looks great against a Rossin paintjob, operates a hell of a lot better, and doesn't cost near as much. Don't waste your money on that overpriced Campagnolo junk, unless it's important to ride with your nose in the air.

Thanks!

I believe one of the Bassos built Rossins under contract sometimes? Could be one of those (or some other sub-contractor)? Regardless, it looks fine to me, and will probably ride just fine. Don't put any of those junky Shee-maino parts on it, though!

Adding to what Syke said, howzabout some first generation tri-color STI?

That thing is ridiculously awesome.

Thanks. There's a SILV marking under the rear brake bridge which I believe is made by Silvato Bilatto and by the way, it will complete with Campy groupset

The Rossin brand was sold to the Basso brothers at some point, who were makers/marketers of rather 'workaday' or "no frills' racing frames, so as you've sorta surmised/suspected, they decaled lots of things as Rossins that might look varying degrees of "different" than a "typical Rossin." Italy had (almost literally!) gazillions of small-to-medium-sized contract framebuilders back than, fwiw, that built for lots of "name brands."

One of my favorites is Biemmezeta (BMZ), who did many (all?) of the Palo Alto framesets (among many others).
