Thank you, Oliver!

Yeah. It's probably a 1in. The dropouts do look smaller. Darn was hoping for 1 1/8in.

The paint is not original.

Any help much welcome.

thanks.

SP in the position of the model designation = prototype.

I don't see, in the photos you've presented, anything out of the ordinary with the frame. Sometimes, in my experience, this designation was used simply before a serial number designation was assigned to a model.

That paint looks to me to not only be not the original, but not performed at the factory, not even as a custom scheme, due to the decals. The TiMax frame in the 2006 catalog was painted at the factory. The bike you have may simply have a finish that was inspired by that catalog photo, or indeed be the catalog bike with a non-factory refinish job.

Decoding CCI frame model
 
My Serotta's SN is CCI 57 006 on what I believe to be a circa 2003 Legend Ti with carbon st seat stays. Tubes are straight, not Colorado. Anybody have any thoughts? Bought it on Ebay three years "refurbished" with new incomplete decals, trying to make period correct.
Thanks

2009 Serotta Legend
 
1 Attachment(s)
I've skimmed the thread, but didn't see this designation for a Legend. I'm told by the seller, which was a shop that it was a 2009. It does have a "custom" sticker on it, but here is the reply to my query.

The frame is not custom. Serotta was doing a program that they called custom but it was NOT custom Geometry. There is no way I would order custom geometry for a stock or non sold bike.

They were also trying to get me any of the original paperwork but never came through.

Doesn't appear to be a custom. The serial doesn't start with a C. Make some measurements and see how they hold up to the stock 58cm geo.

I’m intrigued by the “003” stamping.

The 2009 models known as “ready custom” were the HSG and Fierte with all their permutations. Never saw a mention of the Legend being involved in any custom program (other than the regular Serotta Fit customs) but your serial number seems to confirm the start of a new model’s production sequence. Could we get a pic of the “custom” sticker?

Colorado II production year ID
 
1 Attachment(s)
Hi all,

I recently found a Colorado on Nextdoor for $25 and could not resist. I plan to revive it. It is dirty and has some paint issues but should look nice when done. It is a dark (almost black) green. Has mostly DA 7400 parts.

Going through the various threads here I came up with Colorado II from around 1993 but have not been able to find a catalogue or other picture to confirm.

Here's the serial number "SC58L 3030".

Any pointers are welcome. Thanks!

Yes, $25! Couldn’t believe it when I saw the posting. But it was true.

A little too small for me, I’m afraid. I’ll clean it and see how it feels, then I’ll decide what to do next.

Took off all parts and did a quick cleaning. Definitely needs some work for rust spots and paint cancer but should come back nicely. You can tell it is green only in the sun, otherwise it looks black.
Parts are a wild mix of originals, with DA 7400 brifters, 7402 cranks, rear derailleur and brakes. Wheels are newer as are some of the other parts.
I can't find any markings on the headset. Looks similar to an old Tange or Onza but has cartridge bearings. I'll leave it in as it rolls smooth.
Paint may not be original as there's a sticker by the BB that reads "Painted by Rainbow Cyclecraft, Niwot Colorado". Or was that a common sub for Serotta?

dave thompson 09-21-2019 05:10 PM

Nope, Serotta did all their paint in house. They were know for their excellent paint work.

1992 was the last year for Colorado II production. Guessing that's what you have.

Serotta Titanium Mountainbike
 
My

has this serial number

TH 17 030

any idea what model and year this is?

oliver1850 11-24-2019 01:04 AM

I'll have to think about that one. Would help to have some pics of the frame. Looks like Serotta sized MTB frames in cm through 1999. The 2000 catalog shows sizing in inches. Ti Max was the Ti hard tail frame that year. Will have to check some other catalogs.

1976-78 Serotta Criterium
 
2 Attachment(s)
All,

I just acquired a 1976 to 1978 59 cm ctc Serotta criterium model with the serial number: BS319. See attached images. I acquired it from its second owner, who purchased it for its compliment of as new 1983 vintage Campy Super Record components. He said that the frame was too big for him. I suspect that the '83 SR components were an aftermarket addition.

Wanting to know more about its age class, I tried contacting Ben Serotta, who graciously responded to my query. He said that his records for the late 70s were no longer in his possession but he said that it was built sometime between the years 1976 and 1978. I did find a 1975 frame listed here on this forum with the serial number BS175.

Its quite a beautiful bicycle and I'm proud to be giving it a new home. I plan on hanging a mixed bag of 70s and 80s Campy Record and SR components on it, as well as a more contemporary CX crankset for lower gears more in tune with my aging knees.

Ben Serotta also said that he suspects that it was repainted or the decals were replaced. He said that during that time period he did not clear coat over the decals and that they easily wore off and were often replaced. He said that in this case, in a different manner than the originals. Can anyone comment on this?

oliver1850 12-18-2019 06:49 PM

That's a nice find. It would have had the round head tube decal originally. The Made in USA decal was also different and the S decal on the seat tube didn't appear until the mid 1980s.

You might look for a Campagnolo Triumphe or Victory crank for help with the gearing. They have a 116 mm bolt circle and look right with NR and SR while giving much lower gearing. It's hard to find the small rings but I was lucky enough to land 36/48 Miche rings for mine.

2006 Legend with sloping TT
 
Ebay seller has one posted with the build sheet. Serial number is C LS 56 00714, dated October 31, 2006. So at least the early sloping Legends evidently got an LS code instead of TI.

zambenini 01-28-2020 12:17 PM

Hey, perhaps someone can help me with mine, for some reason I got curious... my eyes are crossing and failing trying to find numbers beginning with HG in this thread. Bike's (far as I know) an HSG cross bike, more recent, but doesn't seem to exactly match the geo in the charts for the era. No 'C' for custom that I can see, unless I didn't wipe enough dirt off the bottom.

HG 56 (size, I obviously get that) 021.

Any insight as to year and geo? Many thanks.

Sorry it took me so long to respond. Your question actually threw me for a loop - I thought it was steel and I had a momentary mind warp :bike: where I was like, "Wha- could it be ti?" (I've never ridden a ti bike so I wouldn't know the difference in ride, but I assume I would notice the weight). Anyway, a magnet sticks to it, so yeah, it's steel.

I think that you need to look for another number. Smallest size for the LT was 52 cm. I'd guess the serial number will look something like LT 52 XXXX.

I'm not so sure that 52cm is the smallest. I just picked up a Colorado LT yesterday and it's a 51cm.

Sounds right, thanks for posting it. I had a T-Max for a short time but didn't keep track of the serial number. Looking at the catalogs, 51 cm wasn't offered at first but shows up in the 1992 geometry chart.

Interesting. I stand corrected. 1992 catalog shows 52 as the smallest size for the LT, but the picture page in the 1991 catalog says it was available in sizes 47-60 cm.

My Serottas
 
I have two CIIIs with red/yellow fade finish from 2001.

The original (CO 59 481) was purchased new in February 2002 just before the move to the new factory. The second (CO 59 418) was bought as NOS on this forum in February 2019.

The first bike has a Kestrel EMS Pro fork, Open Pro wheels and 2 x 9 Dura Ace. The second bike has an Easton EC 70 fork, Open Pro wheels and 3 x 9 Ultegra. Ride wise, they feel the same, although the later is .44 lb. lighter because of the fork.

Still don't have an answer but there's another Meivici currently on eBay that has the MG code. Original owner says it's from 2008. The 2008 catalog doesn't mention any options.

I consider myself lucky. When No. 2 became available, a purchase was a no brainer because I loved riding No. 1 and i had been looking for a triple group to help with my hill climbing trips.

Aside from putting on my preferred saddle, a San Marco Regal, new pedals and bar wrap, the only other change was a replacement of the 52/42/30 chain rings to 48/38/26 TAs. Quite honestly, the 6503 shifts as well or better than any system that I have used, Shimano or Campy.

2000 ish Legend Ti - new to me
 
Duty called in the form of a local post without pictures that said Serotta Legend Ti, 63cm with a low price. Picked it up about 2 hours after seeing the post.

Serial #: CTi 59.5 3078 - Not 63cm, made around 2000/01

Had a full DA7700 group set. In decent shape, I will sell it off.

Guess I'll start with the Alpha-Q fork and learn more about options later.

Have to decide a build strategy, will be a modern group set. Not sure if I want it to be a genuine "road" bike or a special city bike, maybe 1x11 with a Cx group. Links to other good builds welcome.

As I understand it, X indicates a 2010 model. I'm not sure but would guess that your bike was the 981st frame built that year.

The Alpha Q could be original to the frame. There's a picture of an Alpha Q fork on a time trial frame in the 2003 catalog. My CX frame came with an Alpha Q fork, believe it's a 2007 model.
