Another model code
 
Colorado TTR (time trial), circa 1994: TB

Just picked up a cx11. Serial number cx2 54 010

Another Model Code
 
I have a CXII Ti that I recently acquired. The serial number is very difficult to read through the extraordinarily thick paint, but it appears to start with "C2T".

The second number appears to be "555". It measures around a 56cm, so my guess is that it is actually a 55.5cm.

Just bought an HSG and I have a serial number question
 
Hello!

I'm new to this site and just found this thread. As it happens I just bought a Serotta HSG. The owner said it was a 2007 model. It has a titanium frame with carbon fiber fork and stays. It is a very nice bike and I'm looking forward to putting a lot of miles on it!

The serial number question I have is as follows. The serial number is "HB 58 xxx". I can verify that it is a 58cm bike, but according to this thread the "HB" means the carbon fiber HSG. Is this a discrepancy? Or is this the way they identified this type of frame? Or am I missing something?

Thanks!
Scott

oliver1850 12-19-2015 02:46 PM

Most of the codes were received from owners. It's possible someone misidentified a model and therefore provided an inaccurate code. If you're sure of the model of your frame I'd guess the code is correct. You could search the site for similar frames and contact the owners about the model code. Thanks for pointing out the discrepancy.

Doesn't appear that the Fierte Cross has been accounted for... serial starting with FX. Mine is FX 54 001.

Serial #/frame size mismatch?
 
Hi--I'm wondering about a Serotta serial # that doesn't match its measurements. For Serial #C-CT-51-1653, I've got
Seat tube: c-c 52 (c-t 54.5)
Top tube: Effective c-c 54 (actual c-c 53.3)

I know the first "C" indicates custom, but why/how would a serial number size not match frame measurement?

Thanks a lot for any ideas.

Update: The seller has admitted that they didn't want to make the bike sound "too small," so they added a cm to the ST. The serial # is correct.

Serotta frame steel.
 
Have a steel lugged vintage frame with brev campagnolo drop outs frame & fork.
Inside top tube rear brake housing.
Repainted at some point with Serotta stickers?
But no serial # I can see.

Check on the underside of the bottom bracket. Often paint can obscure the numbers. Also the serial number was stamped on the steer tube, you'd have to remove the fork to see them.

Meivici SN question
 
Could someone decode this serial number on a Meivici? MV-54-00029, I am thinking stock 54cm for size, 29th Meivici built. Didn't they start building them in 2006? So what year do you think this one was built?

Thanks

Jack

Keith A 03-02-2016 04:29 PM

Jack -- I think you are correct with you decoding of this serial number. I can only assume that the Meivici's also used the "C" in the serial number if it was a custom.

decoding my serial number
 
This has been very helpful - I have a Davis Phinney from the early 90s, serial number SD562291. It has a custom paint and stickers (Morgul Bismark team) from the factory, so it doesn't have the Davis Phinney sticker on it. Now I got to try to figure out the original year. I might have the original receipt buried somewhere, but curious if it can be deduced by the serial.

Thanks!

Keith A 04-18-2016 08:40 AM

cornelldewitt -- Unfortunately, the serial number won't give you a specific year the frame was built. They include the build sequence in the serial number and therefore the year of manufacture can often be determined by comparing with the serial numbers from other frames.

Are you sure that Morgul Bismark is the name of a team? In the 90s, there was a Morgul Bismark brand of bicycle located here in Colorado. Davis Phinney and Ron Kiefel owned a bicycle shop in Boulder named Morgul Bismark. After they closed it, they sold the name to a bicycle maker who then made bicycles under that name. I wonder if the bike is a Morgul Bismark and not a Serotta Davis Phinney.

According to his serial number and the info posted in the first message of this thread, SD = Davis Phinney Model.

Yes, definitely a Davis Phinney. Just can't remember the date I bought it.

I raced for the Morgul Bismark team back then so I got the team paint and was very close to the shop (Timm Peddie and Tyler Hamilton were also part of the crew). I knew they closed the shop (after I left Boulder), but was not aware they sold the name to a bike manufacturer.

The bike is now a bit of a franken-bike that has literally been sitting in a barn for 18 years, so I'm embarking on figuring it all out. Will probably be posting many more weird questions to other forums! (Who knew Ventana made carbon road forks?!) I'm new at this, so apologies if I'm not very good at it.

It would have to be either a 1990 or a 1991, as those were the only two years the Davis Phinney model used that serial number system. Older ones would have had all numbers in the serial number. I'm guessing it's a 1991 since the serial number is 2291.

cornelldewitt has the info right. Even though the jersey says "Morgul Bismark Bicycles", I believe that was the name of the shop and predates the MB branded frames. The team rode Serottas, but they may have ridden other models besides Phinneys. Note the other sponsors, hope cornell has some Arraya rims. Anyone know what LT refers to?

Where did you come up with that jersey?! I've still got a couple too - including an even older one that didn't have Serotta on it.

I think that '91 is the correct date - the date in the serial sounded really familiar. Couldn't bring myself to dig that deep into my file cabinet this weekend (got a new whip!), but I'm 75% certain I've still got the original receipt.

I raced off-road for Morgul Bismark for a couple of years - still have my custom T-max. I don't have any Arraya rims - as I kept racing for different teams, I kept getting new stuff, and then at the end of each season, I'd keep my favorite parts and put them on my T-max. So it's pretty pimped out with the craziest stuff from early to mid-90s off-road. Halson inverted forks with a Campy high-flange track hub anyone?! Raceface cranks. Gripshift!

I got the Phinney to train on - I have a really long torso and I like aggressive bikes, so getting a Phinney was as much for fit as anything. Then I put a mish-mash of components on it. Ventana carbon forks (prototypes), Campy shifting, Mavic starfish cranks. I don't remember what the rest of the roadies raced on, because all of them had the custom paint which eliminated the model name. Probably Colorado II.

LT was a brand of helmets. The worst fitting helmets ever. I still have a purple one somewhere! Probably should toss it, as it is so old it would probably evaporate in a cloud of dust as soon as it impacted anything.

oliver1850 04-27-2016 12:43 PM

Interesting that they let you spec the bikes as you wished. Were all the team bikes painted the same? I'd be interested in seeing one. I have a Nova Special that I need to get painted anyway.

I have the matching shorts, but perhaps will not pursue the LT helmet.

To clarify, we couldn't spec bikes as we wished - the road team had fully kitted bikes, according to Cat. Cat II & I racers had the nicest Serottas (Colo IIs, I seem to recall) with Dura-Ace components, and on down from there. I raced off-road, so I had a different deal, I got a fully kitted T-max and a deal with Rock Shox (I stitched a Rock Shox sticker on the sleeve of my jerseys!), including the opportunity to buy whatever Serotta road bike I wanted for training purposes at below dealer cost, and I could get the team paint on it. On both my Phinney and T-max, I added different components over the years, as I raced for different teams. Thus the prototype Ventana carbon forks from when I raced off-road for Ventana ('95, I think).

I'll take some pics of the bikes and post them in the appropriate forums this weekend.

Are you sure about the model of your bike? From your pics it doesn't appear to be lugged. Serotta made a companion to the LT named the TG as it was TIG welded. See the 1992 catalog: http://forums.thepaceline.net/attach...6&d=1291899485

1fstwarrior 05-05-2016 07:28 AM

The sticker on the down tube says Colorado Lt. I agree that its not a lugged frame. That's all I have to go on.

I recently got this Serotta and am told it is an NHX. However, I'm not so sure. Anyone have any idea what this is? I know it's painted by Mr. Joe Bell and he's given me some neat info on it. Sadly it is a tad small for me so either my son gets it or it heads to the Bay.

If I'm reading the serial number correctly, it is 80456. That would make it 1988 production, thus a Nova Special rather than an NHX. If you shine a light down the seat tube, you may be able to see spirals when looking in from the BB shell. In that case it would be a Nova Special X, which had SLX tubing rather than SL.

Yup, the serial number is 80456. The down tube is smooth, so no SLX here. Thanks for the help!

Unknown 80's Serotta
 
Hey guys,

I just listed this over at the classified and the general consensus seems to be that it is definitely not an '88 Colorado II as I was told when I bought it from a guy in Tulsa some odd years back. People seem to think that it's an early to mid 80's Nova that has been re-sprayed, but I'm having a hard time making sense of the serials, and haven't run seen any other bb stamped with the Cinelli logo. Note the cable guides just above the bottom brackets. At this point I'm not sure the Columbus stickers are right or not.

Serial number is 76901. Possibility it is 78901, but it didn't look like the top of the "6" closed.

Any help would be much appreciated!

Serotta #80904...TSX decal
 
8 Attachment(s)
Hello, all,
New to the forum and having recently bought Serotta #80904, I've really enjoyed reading through your thread. With what I've learned on this thread the first digit being an 8 my bike is an '88. If the paint is not original it was stripped to bare metal long ago and repainted. However, I bought the bike from the original owner, paid all of $400, and the dusty, grimey, dirty thing I bought is very original according to the seller, who didn't know about the tubing.

Please help educate me on what model I may have. It has no model decals (from what I read this is an indication the paint and decals are not original) and also that very unlikely decal that reads Columbus TSX. I will pull the fork and look for rifled tubing from end-to-end.

Lugs come to a point that curves at the tip, and the brake bridge has two "S" logos. Rear dropouts are stamped "Brev Campagnolo".

Any other suggestions on how to identify my bike are most welcome and appreciated. The old girl cleaned-up pretty well after hours and hours of gentle polishing and waxing. Lots of chips, scratches and even some surface rust, but the one thing the owner did say is it did a lot of racing many years ago. Must have been flat wherever that was as it's a 53/42 with a 21T in the rear. Plan is to definitely save the paint, patina and simply touch it up and stabilize any rust spots.

New Tufo tubulars aleady installed. Ordering some appropriate white bar tape, new cables and housing and searching for a more humane Italian thread 7-speed freewheel

Thanks to all in advance for your help. I look forward to learning as much as I can about my Serotta.

Serotta #80904 Original Paint?
 
1 Attachment(s)
As a follow-up to my posting above I have now pulled the fork and found an illegible serial number (too much surface rust) and the light blue overspray. Is this overspray an indication of a repaint or would original Serotta paint have overspray on the lower end of the steer tube as mine does?

In terms of confirming the TSX decal is just that, simply a decal applied by someone outside the Serotta factory, what does the rifling look like, and am I looking down the seat tube or do I need to pull the BB and look up the down tube?

Identifying what model this is will help determine what tubing the bike actually has, so again the expertise in identifying #80904 is much appreciated.

#80904 Rifling Found Steer Tube
 
2 Attachment(s)
Well, I did some research and it if I understand correctly the very bottom of the seat tube, the entire top tube, the entire down tube, steer tube, and part of the chain stays are rifled. Under 38 years of grime I found rifling at the bottom of the steer tube. If I had not know to look and wipe away all the crud I would never have seen it the rifling.

I will pull the BB and check the bottom of the seat tube and the down tube. From the Columbus TSX vs SLX charts I found, only TSX is rifled end-to-end in the down tube. An SLX down tube is rifled only at the ends.

Yes, the fork may not be original, but once I pull the BB, provided I can see the bottom of the seat tube and up the down tube I'll know if the frame tubing is rifled.

...If nothing else it's fun trying to unravel the mystery of the TSX decal on #80904.

oliver1850 07-04-2016 11:26 AM

That's a nice find. Just from what I can see so far, it looks like an original '88 Serotta to me. I think it's a custom based on a Nova Special. I've never seen those lugs on a Serotta, so the customer may have specified them. The overspray on the bottom of the steerer is normal. Sanding it may reveal a matching serial number. I would do that and grease the whole length to prevent further rust. Note that Serotta used the rifled steerers on everything, even bikes that had non-rifled frame tubes. I'd tend to believe the TSX tubing sticker, unless you find for certain that the seat tube is not rifled. I believe both TSX or SLX seat tubes were only rifled at the bottom. Best way to see the rifling is to pull the BB and shine a light in the top while looking in from the BB opening. You may have to clean the inside of the tube to see the rifling. I have used a wooden dowel split at the end and spinning a piece of sandpaper with a drill.

Regarding freewheels, you can normally fit a standard ISO freewheel to an Italian threaded hub. The thread pitch is the same but the ISO diameter is .003" smaller. There is plenty of manufacturing tolerance to easily allow for the ISO FW to thread on. Here I have a modern Shimano FW on an Italian threaded Chorus hub. I was able to screw it on and off without even using a tool. You will likely find the ratio you want much more easily and cheaply going ISO rather than Italian.

#80904
 
Thank you, Oliver1850. Really interesting to learn that it appears my bike is based on a Nova Special, but also that the lugs used a uncommon on Serottas. Something else points to 80904 having TSX tubing, and that is that the candystripe blue paint treatment was only applied in areas that where the TSX tubing is rifled. So, for example, the entire top tube, but only the first 3 inches of the seat stays. Exactly where TSX tubing is rifled.

It's a relief to the learn I don't have to spring for an expensive Italian thread freewheel!

More to come on #80904 as I continue to unravel it's history, but really, really appreciate the reply and the great information on this forum.

oliver1850 07-09-2016 10:51 AM

The paint is as unique as the rest of the frame. Most Serottas in that era are single colors or fades. I hope you can preserve it.
