The "L" means long top tube. For a while they were using this in their serial numbers, but it seems like all of them from those years had the "L" in there.

As Keith mentioned, earlier in the decade Serotta offered different top tube lengths on their steel frames. For example the standard geometry 58 cm frame had a 57 cm top tube, the long (58L) had a 58 cm TT, and the extra long (58X) had a 59 cm TT. In 1995 Serotta dropped the optional lengths and the L lengths became standard on 53 to 62 cm stock frames. The stock Ti frames were all built with the L geometry.

Marc I recently acquired CU 59 005. Indeed a great bike for my gravel riding adventures. I did change the brakes from TRP 8.4 mini-v’s to polished Paul MiniMotos. Thought you’d like to see it. ![]() Mike Sent from my iPhone using Tapatalk |

I recently purchased a Serotta Colorado from the "son of the original owner" which I thought questionable. Anyway, the serial number looks to be TG5600052. the stamping of the "TG" is very faint so I'm not 100% certain. Bike frame is made with the Prestige TL tubing and is a dark metallic green. Anyone have an idea of the year for this frame? Certain its a 90's model just not certain of exact year. The frame is in very good shape and I've been working to build it up for riding the local roads.

1992.
Dave, thanks for the reply. How did you determine year? One thing I noticed is the bike, although made from LT tubing, does not have LT after Colorado decal. Maybe a year or two later model. I don’t think it ever had downtube shifters on it. Image of the bike after I cleaned it up some attached.

Determining the year is a bit of guess work. The frames' serial numbers are based on the model and then the production number of that model. You can use the catalogs as a reference as to when a particular model was available, and so you can usually narrow this down to a guesstimation of the year it was built.

LT is not the tubing but the method of tube joining, TIG welded instead of lugged. The lack of the LT decal isn't terribly significant. Your bike has cable stops on the downtube, which could have replaced downtube shifters on the shifter bosses. |

Agree with what Dave said, except it's a TG (tig welded), not an LT (lugged). Both had Tange Prestige tubing as standard, but I have it from a reputable source that Serotta often substituted tubing depending on what they had in stock. The TG was the first tig welded Serotta road frame. It was introduced in 1992 and your #52 was surely made that year.

2000 Hors Categorie Serial Number
Hi!
I recently acquired a 2000 Hors Categorie custom frameset that is on its way to me now. I understand the serial number: C CH 48 200 indicates that it is a custom geometry Hors Categorie with a seat tube of 48cm C-C. Do you think the 'CH' in the serial number is an error that supposed to read 'HC' for 'Hors Categorie'? I requested for an elevation shot of the frame from the seller to do some measurements on CAD before buying. Due to the photograph perspective distortion, I'm not 100% certain on the measurements but here are some preliminary measurements extrapolated from CAD based on the seller's provided C-T seat tube measurement of 51cm. Top Tube C-C: 52cm Seat Tube C-C: 48cm (as confirmed with the serial number) Chainstays: 42.5 - 43cm (looks really long but maybe due to perspective distortion) Headtube: 12.5cm This paint livery is very interesting and seems to be used only on the Meivici and never on the Hors. I've never seen this shade of blue before on a Serotta too. Decals look to be all intact from the photos so I think it is a Serotta factory job. I'm thinking this Hors is from 2000 because of the metal headbadge and 'non XL' 3D dropouts. Seller is not the first owner and got this frameset from a local shop that dealt with Serotta. Appreciate any input on this frameset. I will receive this frame in about 2 weeks time. Thank you! |

Interesting, it certainly seems like that might be the case.

I agree with Keith, likely just a mistake. Nice Hors Categorie.

appreciate the work you all have put in. I recently picked up ti bike #808, a 1994 Colorado ti off fbmp from the original owner. who has a newer head badge for sale? the sticker on the head tube just seems cheap for such a quality frame.

I just picked up a Colorado LT that's a 49. TC 49 2239. Interestingly it doesn't have lugs at the head tube or the BB. I could see not using them on the tiny head tube, but the BB lug omission is puzzling. Oh well, I like the fade.
