Does anybody have any idea of the value of my bike if I were to sell it now?

The frameset I linked above evidently sold for $900. Research the recent ebay sale prices of the components on your bike and add $900.

Where can I obtain a replacement derailleur hanger for this model please?

I'm pretty sure the hanger is integral with the dropout, so not replaceable.

Hello, all (but especially AngryScientist, Oliver1850, and Dave Thompson),

Around what year did the Serotta Ti bikes switch from 1" steerer to 1 ⅛"? I'm assuming it was not all at once, but an approximate timeframe would be super helpful.

I'm in the market for a Serotta Ti--the older the better, but the set-up is more important than the actual age:
- I'd like it to be fully upgradable to more modern equipment, thus the 1 ⅛" steerer.
- All Ti, with more of a racing geo than a comfort, touring, gravel, cross, or whatever. No carbon.
- 3d dropouts would be great, because they are sweet, but are not deal-breakers.
- PROBABLY a "55"--I have a 56 Phinney, which is just a skosh too big in height and length (I'm 6' 1" but have shorter legs and a long torso, and now that I'm older the 57cm TT Phinney is too long and I keep finding myself wanting to lower my seat height). Additionally, what Serotta later called a "56" typically has a 57cm C-C seat tube.
- Not crazy about the increasing diameter (and stiffness) tubes in the later Ti models.
- I'm also keeping fingers crossed that it will fit 28mm tires (see this thread for more on that topic).

Any insight on what model & year Serotta Ti I should be looking for would also be hugely appreciated. I am scheduled to go get a proper fitting done, so I can be more sure on the sizing. I know I should just bite the bullet and get a new custom Serotta Ti, but then my wife would chop me up into small pieces and bury me in the back yard.

Thanks!

The transition to 1 1/8" head tubes was mainly in the 2001-2002 range. You could order a Serotta with a 1 1/8" Wound Up fork in 2000 but I doubt many were made that way. Head tube diameter was mainly dependent on what fork was specified. I have a 2002 Concours that came with a 1" head tube and an F1 fork (which was only made with a 1" steerer). You will want to avoid the F1 if you want to run 28 mm tires. By 2003 1 1/8" was standard and the forks were the F2 and O2, both made by Reynolds. I don't remember if I have either of those forks but will try to look. You might start a thread about clearance of those forks in general discussion. There is probably an existing thread on the subject if you want to search.

The Phinney had probably the longest top tube of any Serotta model. A 56 Phinney had a 57 cm TT while the Colorado had a 55 cm TT. There will be customs out there with even shorter top tubes. I think the Legend and Concours would be the models you should look for. Both were available with Ti rear triangles, but in later years the carbon seat stay was more popular.

I did check the forks on my Ottrott and Coeur d'Acier last night. Neither fork has a model, just the Serotta S. I believe both are about 20 years old, so likely S2 or O2 forks. I'm running IRC 28 mm tires on the Ottrott.

Although Brian Smith has stated in other threads that the Attack was not sold with custom geometry, this example would seem to indicate otherwise. At any rate the model code is AK. I'm pretty sure that 2007 was the first year for the model.

This is helpful--thank you!

Keep in mind that any order with custom PAINT garnered a serial number "C."
Painted dropouts on an Attack? Aftermarket or "C," imho.
