Just discovered an alternate serial number location, this on an early to mid 80s Club Special. It's on the inside of the drive side dropout. I knew that some TriColorados (possibly other frames with Ritchey dropouts) had the serial number on the inside of the dropout, but the Ritchey dropouts have a big area above the axle nut interface that is protected from damage by the axle nuts. It's a pity that I can't read more of this one, as I've wondered for years about its vintage. Not much to go on as it has been repainted.

Anyone with a Club, Nova, etc. from the early 80s with a readable serial number in this location? I'm pretty sure I've seen Clubs and Novas from 1983 on with serial numbers on the BB shell, so I'm guessing that this Club is older.

Couple of other random serial numbers:

1983 Nova Series: 83823

1989 Nova Special X: 90190

I would like to know if 823 is the 823rd frame built in 1983 or the 23rd frame built in August.

Same with the 89 frame: 190th frame built in 1989 or 90th frame built in January?

I'd love to find a frame with a serial number such as 91302 to resolve this question.

year help please??
 
serial as follows:

C TI57 2045

It's a 57cm CTI, that certainly seems to be newer than my '97 CSI (by groupset age anyway; a slight contrarian piece is that I've got a paint-matched carbon F1 on the CTI but a fatty F3 on my '97 CSI - but the F3 wasn't even made 'til '06, correct? so, that was added as an upgrade later for the previous owner, I'm sure), anyway, I would sure appreciate a "Serotta-expert" 's opinion on the 2045 part of the s# to help me figure out the yr.

45th built in 2000? 5th built in 2004? I'd think for consistency they'd want to go to 00 for 2000. ?? (then they could do 01,02,...10,11,12, etc not that it makes a difference now, unfortunately!)

Thanks, all! appreciate the advice in advance!

I don’t think your bike is a CTI, I think it’s a legend Ti with custom geometry. The ‘2045’ is the production number of your bike: the 2045th one made.

Dating a bike by its groupset is always a crapshoot, unless you’re certain it was purchased with the installed components.

oliver1850 02-03-2019 03:24 PM

I agree with DT: your frame is a custom "Legend", though in some years Serotta simply called them "Ti". Best way to figure out the year is to look at frame details and paint. If you are lucky you might locate one with a close serial number and an owner who is sure when his was built. Searching classifieds and gallery posts might turn something up.

Thanks for your responses, Dave & Oliver...
The ride in question here has "TI" on the top tube & has (as close as I can measure) seemingly identical geometry to my CSI. Which would seem to me to make sense as the "titanium" version of the superlight steel framed ride, right?
So am I thinking this correctly...was the "Legend" essentially the Colorado geometry??
I know trying to use the groupo as an indicator is not too reliable:bike:, just trying to use it as one of the clues, since the serial # doesn't seem to be too helpful! It (again,) seems like original equipment - 10spd DuraAce... soooooo...possibly '03???
thanks again!!
Jeff

Yes, geometry was exactly the same for CSI and Legend in the 1998-2000 range. I think that's about the right vintage for your frame. If you look at the 1998 catalog, the Ti is painted just like yours, only in red. Yours looks to be Big Boy Blue, very common on Serottas in mid to late 90s.

Can anyone help me with this one? Just making sure it's a Classique but can't find much about it. And the serial number and orientation matches nothing here...

55 LG A0192 is the serial.

My latest, and final, Serotta has only numbers: 66024.

It's my 3rd one (after a Nova and CSi) and my favorite of all. :banana:

Columbus tubing. Flat crown fork. Fast back seat stays.

Says Serotta on the chainstays...

And Murray on the seat and down tubes. :cool:

I'll post a pic one day. :)

I'd say that's a 1986 model. I'm kind of surprised by the fastback stays. It appears that the one pictured in the catalog has side track stays.

Are the logos bead blasted into the tubing? Certainly must be a Classique.

Yes! Every single logo is (head tube, inside NDS seat stay, top tube, down tube, etc). Does this indicate it's the newer 'relaunch' of the Classique? Were the newer ones offered with semi-custom geometry? I ask because the head tube is a different size than indicated, and a few other measurements did not match the 'race' or 'percormance' geometries given...

I've been riding it a few hundred miles now and it is STIFF as stiff can be. I absolutely love it, wouldn't be as happy with it if it was my only bike though.

That would be my guess. I would think that Serotta would have modified the geometry for anyone who was willing to pay for it. You might ask Brian Smith about it.

Here's a Wayback Machine page from 2011. Doesn't show the bead blasted logos. Maybe looking at other Wayback pages will turn up more info.

Great find. So on the decals, you can select "ti charcoal" or "charcoal ti." I wonder if one of them is bead blasted, since it is I guess a charcoal color. And it looks like they can be made in full custom geometry. Thank you for the assistance and link!!!
