The Chainlink

For Sale: late 80's early 90's De Rosa.

This was given to me by my dad however I do not ride it much.  Bike is in amazing condition, all decals are good, no scratches and recently had a tune up.  I don't want to part it out, would rather find a person who wants to ride it. This bike is super light and was made before Trek took over the company so its a hand made frame. Think it's a late 80's or early 90's production.  Let me know if interested. Not sure on the size, if you tell me what part to measure I can do that and get back to you.  $1200 obo

That looks to be a lovely bike. The Campagnolo Delta brakes are very desirable parts for collectors. Other than the Dura-Ace rear derailleur, it's not clear how it's equipped, but I assume it has similarly high quality wheels, front derailleur, stem, handlebars and seatpost.

There are three common measurements which convey the size of the frame:

  • seat tube - center-to-center
  • seat tube - center-to-top
  • top tube - center-to-center

The seat tube is measured from the center of the crank spindle to either the top of the seat tube or where the seat tube intersects the center of the top tube. The top tube is always measured from where the center of the seat tube intersects the top tube to where the head tube intersects the center of the top tube. If my description is confusing, there are a number of diagrams available from Google Images which demonstrate exactly where to measure (ignore all diagrams except those that show horizontal top tubes).

Though most frames are specified in metric sizes, measurements in English to the nearest quarter inch are sufficient. Few of us have metric tape measures, but we all have calculators and Google. :-)

Thanks for the info on the measurements! I have no clue how well its equipped. My dad was a serious rider but sadly I am not.  Once when I took it in to get a tune up the guy told me that everything was really good quality except for the tires and rims, he said there is newer stuff out there that is better. I think it has the original parts for everything. I have never added or replaced a thing on it. Hopefully I can find a good home for it, all it does is collect dust at my place.

Maybe we just need to get you out there on the roads a bit. :-)

I'd be interested in it if my bike stable wasn't full and my wallet empty. It looks like at least a 57cm frame, maybe 60.

As Skip implied, more details will help the sale.  The Deltas are a love/hate item, but are certainly valuable.  It looks like the brake levers are Campaganolo.  What are the hubs and rims? 

What's the tubing?  SL, SLX, etc. - should be on the seat tube sticker.

I've always wanted a DeRosa.   Happy to help with any size/component ID questions.

Where on earth did you hear that Trek owns De Rosa? This is news to me...

Somebody told me once that the son took over the company and moved the production facility, that they are no longer hand made and then later sold it to trek. All or none of that could be true i dont know. I will post pictures of the other components.

It appears that De Rosa is still family owned and made in Milan, Italy

Scroll down... Nuovo Classico and Primato are steel. They'd probably go out of business if they didn't build "plastic" bikes as well. http://www.derosanews.com/english/derosa?categoria=0

They are one of the few big-market bike companies that still offer steel (in something other than a touring setup).

Frames aren't cheap though... http://www.wiggle.com/road-frames/

I wouldn't consider De Rosa a big-market bike company. Weren't they at the NAHMBS in '10? I'm pretty sure they're welding those frames themselves. I'd assume they're outsourcing the manufacturing of the carbon frames. 

Bianchi, Gary Fisher, Jamis, Trek, Specialized, Surly, Raleigh, Salsa have non-touring steel bikes. I'm sure i'm missing many more companies.

Cinelli still makes a few steel frame models. The Supercorsa still has a horizontal top tube, to boot.
