Trying to decode this Serotta CSI
 
1 Attachment(s)
Just picked up this CSI. Can anyone help with the year of manufacture? It's serial number CC 52 904, which I understand is an early CSI. Most had "CS" serial numbers. It has lugged C4S tubing, braze ons for downtube shifters, an F1 fork, and external cable routing on the top tube. No date on the World Champion decal, or on the "Serotta EST 1972" decal. I'm guessing its a 96, but its a guess. Build suggestions are welcome too! Thanks.

Dave, late '96 or early '97 would be my guess based on the serial number. I have CS #958 here. It has the HT cable stops which I'm pretty sure debuted in 1997, but the older Serotta/Columbus blue and gold tubing sticker. Your frame is a custom, so someone may have specified the DT shifter bosses. Don't know what's up with the tubing stickers. Perhaps your frame was repainted. There's no mention of C4S tubing until the 1999 catalog. The CSI in the '98 catalog has the blue and gold tubing sticker.

I'd build it with period correct parts. 7400/7410/7700, Athena/Chorus/Record 8 or 9 would all work for me.

Hello, this is my first post. I’m Just starting to get into cycling. I’m looking at a Serotta Colorado AL. The serial number KU7B0230 it is Blue and silver with yellow stickers. I’m thinking about buying it and I’m trying to find out some history or any information on it. Maybe the year or more. The SN# here do not seem to line up with what I’m reading on the forum. Is it really a Serotta? Thanks for your time.

brdiver -- Welcome to The Paceline and cycling!

I don't know much about the Colorado AL frames, but these were made by Kinesis and then finished by Serotta -- which is why they have a different serial number. I believe these were made in the late 90's, but I don't know how long they were in production. My guess is that they don't command a very high price. You can search the forum for more information on these frames.

oliver1850 10-04-2017 03:38 PM

+1 on what Keith said. I have a Colorado AL. I paid $200 for the frame and Kinesis carbon fork a number of years ago. They were made for two or three years starting in 1997 or 1998. Not one of the more popular Serottas, and the one you are looking at has the less desirable aluminum fork. Looks to be in good shape though and would be a decent starter bike.

That's correct, so it is the 1198th CSi built. Too bad all the build specs for the custom Serottas were lost, unless the owner saved this information :(

Any idea of year of this 1198, maybe Dave Kirk would have idea?

Take a look in this discussion and you should be able to find some dates and build numbers that would give you an idea...

Mine is CS 59 958. After going the the same process as you, I settled on 1997 for mine. Small details such as tubing sticker, cable stops and paint will help pin it down but I'd guess 1997 or 1998 based on my serial number.

Maybe I missed it in the previous 20 pages, but I have just seen a Ti cross bike with the code CGT. I understand the C...it's definitely custom geometry.

It's being advertised as a Legend.

Any idea if this is correct?

Rosco827 04-23-2018 01:57 PM

Hello, I am getting ready to list a Serotta bike frame for sale (husband's request). It was a shop display model he purchased and never built up. The bike shop said it was Ottrott SE, but when I look at the serial number it indicates an Ottrott ST. May I ask what the difference is? Is it possible to be an SE?

Serial number is OS 58 1409

Rosco827 04-24-2018 10:18 AM

Any Serotta knowledgeable folks who can help with this?

I think both models are essentially the same. Both have the carbon stay and pivot at the dropout. The name changed to SE in 2008.

I checked my Ottrott. It has the IT decal on the carbon seat stay and the model code in the serial number is LI, so that is evidently how the early ST frames were designated. It's possible that the frames with Ti seat stays were also LI though. Need to see one.

Sorry, just saw your post. Is there a tubing sticker? Most Legends have C4Ti. Concours was C3Ti. Either will have tapering OD seat and down tubes. Legend TT is 35 mm at the HT and 30 mm at the seat tube. Concours has a 33 mm straight TT. If it doesn't have tapered seat and down tubes, it's a lower model like Fierte.

Rosco827 05-03-2018 11:18 PM

"The name changed to SE in 2008"
Thank you, yes, the tubing sticker says SE and it is a 2009, so this makes perfect sense. Thank you.

There's a Concours CX on ebay that I was interested to see has the same CT code as Concours road bikes.

My Very Strange Coors Light Serotta
 
5 Attachment(s)
I have a Coors Light that I acquired from an acquaintance not long ago that should not exist. He purchased the bike as a new frameset in the early nineties and built it for racing with his New York based club. It is finished in the yellow/purple paint scheme with Campagnolo badging that first appeared in team photos in 1993. He had a yellow/red model prior but was not happy with the sizing and this was available. He assures me that it was purchased new and never repainted. I know for a fact that its been siting for decades in his basement. Now here is where it goes crazy. The serial number is 90977, no letters. This means that it a 1989? It has the combo fillet/brazed head tube attachment and the expanded tubes at the bottom bracket are likewise fillet brazed. Additionally it has top cable guides which theoretically ended in '92 although I have seen pics of team riders with the top tube guides on later bikes. I have compared the frame with a '94 and its a perfect match, even the iridescent purple. I have no reason to disbelieve my acquaintance so if his recollection is correct, did Serotta just paint up a leftover bike that was siting around to meet a delivery requirement? BTW does anyone have a Colorado fork with a min of 147mm? I can't seem to post on the classifieds board.

oliver1850 05-30-2018 02:41 PM

I think it is an older frame, likely a late first generation Colorado. Note the lack of S bend chain stays and the top of top tube tube brake cable routing. 1993/4 CRs and CRLs would have had internal routing, though Dave Kirk said real team bikes may have lacked internal routing. It's possible this frame was hanging around unsold somewhere and was painted with the Team paint circa 1994. I know of one circa 1986 new Serotta that was sent back to the factory by a dealer for a repaint before it was ever sold.

You need 30 posts to post in the classifieds. I'll post your WTB and refer replies to you.

jrsbike 05-30-2018 03:43 PM

Thank you for your comments. They confirm my suspicion that this is a left over that received a later paint job. I like the back door heritage of it and enjoy the interim construction solutions. I'm very anxious to get it on the road. Thanks for your help with the fork.

oliver1850 05-30-2018 04:40 PM

No problem. You should double check the steerer length needed.

I think the F1 fork was introduced right at the end of the Coors Light era. Don't know if the team ever used them, but might be an option if a steel fork doesn't turn up.

I have a carbon fork from a LeMond Zurich here that wouldn't look bad if repainted. Would need to be threaded down a bit if you don't want a spacer.

jrsbike 05-30-2018 11:07 PM

Hi and thanks again for your help. I'll let you know about the LeMond fork if nothing turns up. I do remember seeing a team bike with a matching purple F1 fork but maybe it was on one of those mysterious Coors Light titanium bikes which never seem to surface. I had actually considered finding an earlier bike and making a Huffy clone but his came up and it was love at first sight, especially when I saw the bottom bracket construction.

Puzzling Meivici serial number?
 
I am looking at a Meivici with a serial number which reads C-MG-48-00051.
I thought Meivicis had 'MV' in their serial number. What does the 'MG' stand for?

Thanks, Jack

oliver1850 07-31-2018 04:14 PM

Haven't seen enough Meivici serial numbers to have much to go on. The only option I know of besides geometry and presumably stiffness was sloping vs. level top tubes. Don't know if slopers had a different model code.

Hi all,
Fitst post to this forum.
In Australia,picked up a csi recently.
Have tried to made sense of serial numbers but the last 4 digits don’t quite correlate from what I can see
CS 57 1140
While not a custom,does appear to have a Serotta engraved steerertube extention.
Thanks in advance.

The last 4 digits of the serial number are the production number of your bike: the 1140th CSi built.

Stevendavid75 08-22-2018 10:42 PM

Thanks Dave,
So based on that, are we able to get any idea of when it was built? And by whom?

Thought CR was in the list, but it appears not. Many more are mentioned in the thread. The Colorado Legend CR was the frame that replaced the Colorado II in 1993. You have the 9th one built, a stock 52 cm.

My CSI is #958 and from what I've been able to determine based on CSIs owned by others, it's a 1997. If I'm right on mine yours should be in the 1997-98 range. Some colors were only offered in certain years, so that can sometimes help pin year down. Check out the 1998 catalog. Unfortunately we don't have a 1997 catalog.

Dave Kirk might be able to tell you more about the builder. I believe he did a lot of the customs. There were probably several guys doing production brazed bikes in those years.

dave thompson 08-24-2018 07:02 PM

New Serottas were delivered with a sheet signed off by the people that were involved with its’ build, about 6 to 10 signatures on each build sheet. No one person was solely responsible for the frame.

Thanks for the update -- I didn't think it was anything rare, but was suprised that the CR designation wasn't listed. Looked thru the thread, didn't see anything like it, but apparently read too fast...

I'm sure that's true with production frames. Makes sense that one guy cut tubes, another brazed, etc. I know Marci did finish work in the early days. Thinking Dave has said he built customs and team bikes pretty much on his own, at least some years.

I didn't read through it either to be honest but fairly sure about the CR model designation. Colorado Legend/Colorado CRL was the other lugged frame at the time ('93-'94). It's in the list as CRL.

Just guessing that your frame may have an unusual paint job or has been repainted, as CRs normally have the model name on the top tube. Even if painted as a new frame at the factory someone may have specified a decal color that they didn't stock for every model. That typically resulted in frames with either a small Serotta decal in place of the model name, or nothing at all.
