is that Dura Ace?

I've got a pair of RSX-100's you can have... though they're a bit lower on the food chain than DA.

Exactly what I was thinking. Goes distinctly against the mentality that you "have" to have everything made overseas to even be competitive. My lust for those bikes has just increased.

I fell in love with Serotta when I was back in Indiana last year. I'd always being doing my route and on the way back in I kept seeing this ridiculously gorgeous yellow frame with a mysterious "S" on it. Finally my curiosity got the best of me, I rode up to the guy and asked him about his bike. We rode together a little while but he couldn't hold my wheel. Must've been the engine, not the bike

Serottas are really, really nice frames - although some of the custom ones can have pretty goofy geometries. They also are extremely expensive when bought new, but you can find some surprisingly good values for used Serotta frames. Quite a few of my riding buddies have Serottas and they are very cliquish about their bikes, but I wouldn't hesitate to buy one if the price was right. Unfortunately, their new frames are way out of my league.

What is a Colorado TG? There is one listed near me in my size but I don't seem to be able to find any information on it. The seller says it is from the mid-90s.

Thanks guys/gals.

You might have better luck researching/asking at the Serotta forum. Here's a cursory Google search of that website:

Thanks, I just joined their website this afternoon but I am waiting for the confirmation email.

I may be wrong but I believe Colorado was a model name and TG likely refers to a Tig welded frame (sans luggs) rather than a brazed lugged frame.

See my post above for a pic of a Colorado TG. TG stands for TIG weld, which means that the tubes are welded directly together without lugs. There is no performance or quality penalty and the result is slightly lighter than an identical lugged frame, although C&V collectors preferred lugs for their aesthetic value.

Here is the 1994 catalog that explains more.

serotta made the 7-11 team bikes for a few years prior to Merckx sponsorship. At the time he was usuing some pretty experimental true temper tube sets. Serotta claimed the manufacturer was pushing him and when the frames started to crack like crazy Ben vowed never to be pushed around by a manufacturer again. Merckx took over 7-11 bike sponsorship and serotta moved on. The early 1990s columbus was custom drawing tubesets for serotta (seen on many a colorado with the oversided DT at the BB). Columbus continues to draw custom tube sets for serotta today and a custom colorado full steel bike with custom shaped columbus tubes can be had for under $3000 CND today. A pretty good price given the prestige and history behind the company.

Serottas were very nice bikes. We use to sell them at the shop I worked at in the late 80s early 90s. We had the fit cycle that Serotta also had available for his dealers. There were a couple of models but I don't recall all of them (Colorado, TG, and a Titanium) There were also several different ways to order your bike. 1. A production bike that was no different than any pre-built high end bike that you may purchase from a showroom floor. 2. A customer would pay for our fit cycle service and try to find a Serotta that "fit" right for them. Basically we would set the fit cycle to Serotta's production geometry. (which if i remember correctly varied per model and several different setting for one sized bike. i.e. 56cm std and 56 cm long) Then the customer would select their paint job, decal set, etc. This was the most common form we sold because it was quiet a bit less expensive than the 3rd option and the customer could still get a completely custom paint job. 3. A completely custom frame adjusted via the fit cycle.
It was a pretty exciting experience as a mechanic to receive these bikes in and assemble them for a happy customer. I think anyone who was a mechanic for a few years will know that you really don't get to work on "dream" bikes all that often. The variety of components was pretty fun too. A lot of Dura Ace and I even got to work closely with Mavic Zapp. I remember working on a Titanium Serotta with a cool half natural and half British Green paint job. It sold for $5500+ and that was in 1991.

My uncle has two hanging in his garage, one with a mix of sachs-huret/mavic, and one built up with campagnolo. One day, they'll be mine.

Here are some pics of my wife's Serotta. Ben custom-built the frame for her in the mid 1970s. She has ridden and loved it ever since. It still has its original paint & stickers. I've never seen an earlier Serotta, although there were a few. It is as fine a bike as any I've known.

The C'd'A is an especially nice Serotta. I lust for one; can't afford a new one; missed one one eBay a few months ago; they don't come up that often...
