That's my guess, especially given the 4,5XX serial number. Doubt there were 1,000 DKS frames made of all models. I've yet to see an Ottrott DKS except in the catalogs. The 2003 catalog shows DKS available on Ottrott and Legend but there was no Hors shown that year. So at some point the HC was phased out in favor of the Legend DKS. Not sure how one with a Legend serial number ended up with HC decals, other than these kind of discrepancies are common with Serottas.

I came across a local seller who provided me with the following serial number

CNV56455

I did my best to parse through this thread, but I didn't immediately identify a reference to any "NV"

Hoping for some guidance and I apologize if i missed something obvious previously posted.

Thanks very much

What does the seller represent the frame to be?

Hey thanks for the quick response.

Seller represents it as an Ottrott

I hate to be cynical, so that's why I'm checking with those who are in the know :banana:

dave thompson 04-12-2021 02:44 PM

Have the seller send you a pic of the serial number. It’s possible he’s mis-reading the number.

Also have him send you some pics of the bike, particularly of the rear dropouts and of the Ti/carbon joints. I think it would be hard to fake an Ottrott.

Turns out to be a Nove; I now can understand the confusion> I guess we can update the list to include "NV"

The drop outs have bosses without bearings, however they are difficult to distinguish between models (Nove vs Ottrott)

I just finished my winter build and I love riding it. Based on the 93/94 catalog, I believe that is the year. I was hoping someone could verify whether or not that is correct. The serial number is CRL54 00004.

Thanks in advance for your help, Mike.

dave thompson 04-30-2021 09:43 PM

With a serial number of 00004, I’d guess 1st week of production for that model. Maybe even 1st day!

oliver1850 05-03-2021 02:04 PM

Agree with Dave, surely an early 1993 model CRL. Guessing it would have been built in 1992 as they would have had to build some for the catalog photos.

I'd appreciate some help in decoding this one -

https://forums.thepaceline.net/showp...3&postcount=68

I assume the following, but it's just a guess:

BS = Ben Serotta?

12880 = December 8th, 1980?

RS = ???

58 = 58cm frame - This does match the frame size.

112 = the 112th frame built that year, or month?

Could "RS" = Road Series?

oliver1850 05-31-2021 11:49 AM

I suspect you have it right, but I haven't owned any bikes with BS serial numbers.

The serial number on my bike is CCO 60 1245. The Serotta production card is dated April 29, 2003. I bought the bike new and I'm still riding it.

I just inherited CSI serial number CS 58L 618 and would love to know more about it. I removed the old Ultegra triple setup and am in the process of doing a restomod with a mix of Sram 1x components.

Thanks for posting that. I wish we had more of these.

Nice CSI. The model was introduced in 1995, replacing the CR/CRL as the top steel model in the line. I'd guess 618 would probably have been produced in 1996. I have #958, produced in 1997. It has the 25th anniversary decal, and has head tube mounted cable adjusters.

1980's Serotta, serial number 5452.

Hello. I have a 1980's Serotta, serial number 5452.
Stuff I remember when I bought it:
The dealer was in San Jose Ca area. I recall they had 2 Serotta frame models, one race geometry and one touring geometry. This is the race model. Does anyone know the actual model name of this bike? (if it had one). Thanks.

oliver1850 06-21-2021 02:29 AM

I think the serial number indicates that it was built in April of 1985. I would need better pictures of the details of the frame to guess what model but it's most likely a Club Special.

Szttmn 06-21-2021 07:31 AM

the only serotta in brazil might be mine ;D
 
Hi, I'm negotiating a serotta build and just asked the owner for it's serial number (CNV 53.5 188), for what I understand it recalls to a Custom Nove, seat tube 53.5, production number 188.

As you might imagine, this is the only serotta bike up for sale here in Brazil and I think it might end up being mine, so I'm trying to get to know as much as possible about it before the purchase.

For what I seen, a similar bike with 182 serial number was posted up for sale somewhere with 2005 year in the description;

For the headbadge, I'm not able to extract any info yet

Thank you for weighing in on this! I hope these additional photos help. Cheers.

It might be a Nova Special. The only differences I know from a Club are that the Clubs I have seen have an engraved fork crown and are made from SLX tubing, while the Nova is SL. You might be able to see the spirals in an SLX seat tube from the top, but it's more likely to see them with the bottom bracket removed.

I think you have it right, a custom 53.5 Nove. Since it is a custom, be sure that the top tube length is right for you. Great bike, 2nd in the line to the Meivici.

Thanks! The previous owner really got into cycling in the mid-90s, so that tracks... probably when he decided to throw down for a new Serotta.

Trying to determine year my CSI was built
 
3 Attachment(s)
Hello,
New to the forum, but a vintage cyclist (53yrs young). I have a CSI that I am trying to determine what year it was built. The serial number is CC 59 1114, what is strange is that the top tube is long like 60.5-61cm ctc, the seat tube is 59cm ctc and the head tube is 176mm, it has a F1 carbon/Ti 1" threadless fork.

Unfortunately this bike just sits as it is just a little too large/long for me, it is for sale as a frame/fork/Chris King headset/Deda 100 cockpit. It was resprayed with Dupont Imron and is stunning in the sunlight.

Great looking CSI. Serotta was building at least 300/year, so I'd say yours was made in 1998. Might have been made in 1997 but no way to tell without the original paint (and anniversary decal). Standard geometry CSI would have CS prefix. Your CC designates custom geometry, so that explains the long top tube.

The 1998 catalog shows head tube mounted cable stops instead of the down tube shifter bosses. That may or may not indicate that your frame is a 1997. Since it's a custom, the buyer may have specified DT shifter bosses.

Hey all, figured this question from my other post most get some more traction in this post...

Serial # CLS 57 134

I know this is a custom Legend ST, 57cm seat tube, and was the 134th built.

My question is this, what year do you all think this bike was built? It has the C4Ti tubing sticker and an S3 fork (can't confirm if fork is original though). I would assume this was a somewhat early bike, but since I have no idea how many of the Legend STs they built...

Thanks!

oliver1850 07-28-2021 03:25 PM

I would say 2003 or 2004. If it has the exterior milling on the head tube it would be later.

Thanks, that's kind of what I figured. I don't think my HT is milled from me looking at it (seems pretty straight).

oliver1850 07-30-2021 10:15 AM

I think that you would notice the milling. It leaves a definite ledge near the top and bottom of the front of the head tube that tapers off into no ledge at the rear.

henrypretz 09-23-2021 09:14 AM

Hey there Serotta experts - I am looking at a bike that I can’t quite figure out the “model” of. It is Ti and is described as an all arounder and not necessarily a purpose built cross frame. Linear pull brakes. 3D type dropouts, down tube cable stops.
Serial number reads CCU 54 055
I was under the impression that the first “C” indicates custom, but don’t know model what the “CU” would identify as. Or is the “CC” indicative of a Colorado and the “U” something else?
In the end it doesn’t really matter, but would be nice and kind of fun to figure it out.
Thanks in advance.
Henry

oliver1850 10-06-2021 10:29 PM

I would say it's a custom and the model is CU. Some detail photos might give a clue as to what the model actually is. 1 1/8" head tube? What is the fork? Does it have down tube shifter bosses?
