Help with my BENOTTO 850

Hi all.

I have a BENOTTO 850 with Columbus Zeta frame. Is this frame steel? I think it's a 1980-ish vintage or somewhere around there. Full Campy SR - everything. Really.

Does anyone know if that frame is steel or ?????

Does anyone know about these 850 models? Were they a high-end model? I am guessing they were, given the top-of-line parts.

Any help you can give me will be greatly appreciated. Thanks.

I think ZETA tubing wasn't around in the earlier part of the '80s. The Columbus commonly used then would have been Aelle on the less costly frames, and SL or SP on the better models. Mid '80s was when SLX was popular. I really don't know when ZETA came along. BTW- if it's steel a magnet will stick...

The Super Record group was no longer popular after the mid '80s, so it's a little surprising to find it on a frame made of ZETA.

My '82 Romani (a pic of it in the "Show Your Resto" thread) was built with Zeta tubing and yes, it's steel. There's not much info around about it and some weeks ago I started a thread about it with 0 replies. What I've gathered after corresponding with the factory and people from the business is that it was a "cold drawn, high quality tubing", according to Columbus. It was carbon-manganese like Aelle -which came later- with plaing gauge, 1mm wall thickness (Aelle was 0.8). A frame builder described it as "sturdy, dependable and club-racing quality, but not high tech"
What I know for sure after all these years of use is that it's not the lightest tubing around but you can build a 23.5lb bike with it. Sturdy it is. In '85, I crashed the bike and bent the top and down tubes. These were straightened and the frame brought back to its natural geometry. I've been riding the bike ever since without a single issue.
BTW, it would be nice to have a pic of the tubing decal. I repainted my frame and used a generic Columbus one.

The Benotto 850 used Columbus Zeta tubing from 1984-1986. Prior to that it used Ishiwata 019. I have no records of this model for 1987. Clayface's comments on the tubing composition, guage and type are correct.

The full name is the Benotto 850 Paris-Roubaix. Basically, it was marketed as club/entry level racing bicycle. The original price varied from $400-$450 US, depending on the year.

The 1984 model originally came with SunTour Vx derailleurs, SR crankset, Cherry brakes and Miche hubs laced to Ambrosio Elite rims. Interestingly, the frame was also available with optional, Tange #1 tubing for $50 extra!

The 1985 model used Campagnolo 980 derailleurs, Nervar crankset, Modolo Corsa brakes and the Ambrosio Elite rims.

The 1986 model used Campagnolo 980 derailleurs, SR crankset, Modolo Flash brakes and Miche hubs laced to Nisi tubular rims.

So, the model appears to have been in quite some flux, but the Super Record components you have are obviously replacements and well above the original components. Normally, Super record components would be found on a frame using Columbus SL or SLX tubing.
