Hi folks -
There is a 58 cm 2003 CIII on ebay that looks nice
CIII on ebay (http://cgi.ebay.com/FOR-SALE-58CM-SEROTTA-COLORADO-III-WITH-O2-FORK-NR_W0QQitemZ7214190553QQcategoryZ98084QQssPageName ZWDVWQQrdZ1QQcmdZViewItem#ebayphotohosting)
What tubeset was used on the 2003 CIII?
How does it differ from the current Spirit tubeset used?
Thanks
Will

New tubes are tripple butted, 2003 was double butted I think. New should be lighter for a given tuning, and I was told the tripple butted niobium bikes were slightly smoother, but not likely significant enough to notice. Also I read on here somewhere that the seat tubes were not as oversized in the past as they are now, and that affects ride. But I am no expert on that. That my $.02. :bike:

It should have been the C5S tubeset in 2003. The difference to the current tubeset is the now round TT which was in ColoradoConcept shape before (I don't know why Serotta skipped that CC TT).

If its a 2003 its probably the C4S tubeset. I bought my CIII in Nov. 2003 and its C4S. I believe that tubeset was triple butted as well; the newer Spirit is supposedly a tad lighter and thinner-walled. I haven't ridden a Spirit CIII so I can't compare them. I wouldn't worry too much about tubesets though, they make less difference than they'd like you to believe. Bottom line- its a nice frame, and that paint job is pretty hot.

That is a beautiful frameset.

It looks like a faux ti frame.

The CDA (was CIII) does use the Columbus Niobium steel alloy, as does the seperate Columbus-branded Niobium steel alloy tubeset named "Spirit," but the made for Serotta Niobium steel alloy tubes are not "Spirit" tubes.
It's hard to say "from here," but that EBay frame looks to be made with very current production tubes, and they look to be from among the oversized variants in the "pallette."
Buechse - the CC shaped top tube has not been skipped, it's still used, in multiple diameters. Maybe you are confusing it with a less expensive Fierte which would not have that tube shape.

Are you referring to the top tubes that were horizontally ovalized at the forward end? Or the round tubes with a slight flare towards the front? Were both of these being used at one time, or did the latter take the place of the former over the years?

Brian, I'm not sure about this.
In the current model info pdf it is said like shown below. Nothing about CC. And looking at the picture that might be correct. That's why I thought they changed to a round, but triple butted tube.
But I have to say: I really don't know.

Not simply ovalized (squashed), the top tube grows in horizontal diameter as it approaches the head tube, but maintains the same or very nearly the same minor diameter in the vertical plane. I suppose that since the original Colorado Concept tubes (which were steel) did not include a top tube cross-sectional shape other than round, that maybe it is techinically incorrect to call the top tube with the ovalish shapes at their fronts (though they are not simply constant diameter tubes then ovalized) "Colorado Concept."
Regardless of the textual wording or all nomenclature, I can assure everybody that all '06 CDAs have had the particular Serotta cross-sectional modulations that people have known in the past.

That's nice to know about, Brian! I really was wondering how they could have skipped this.
best regards,

Brian, do you (or anybody else) know how that is solved on the 06 Nove? In the description it is said it has a Colorado Concept TT. Is this the same shape that you described in your thread or is it just a constant diameter round TT?
Thanks for any information.
Regards,
Peter
