Bicycle Mechanics - Steerer tube question

I was thinking of purchasing a carbon fork for my road bike. To order I need to know the size? 1" or 1 1/8 "? Integrated or not? How can I tell what i need to order for a 2001 Trek 1200? And is there anything else I might need to know?

Measure your steerer tube. Easiest way is to take off the top cap of your stem. As far as integrated goes, look where the headtube and the fork crown meet. If you can't see the headset, it's integrated.

I'd be willing to wager that it's 1.125" and I'll guarantee it's not integrated.
If you take it to your LBS, they can tell you for sure, plus if you get it from them they might just take care of removing and installing the crown race, cutting the fork, and all that fun stuff.

Why are you so confident in your answer? That is the insight I am looking for. Something that would trigger that confidence?

Newer aluminum frames have 1.125 steerers, while steel is more likely to be 1". A 2001 wouldn't have an integrated headset either.

Look up the paperwork on the Trek website, or send them an email asking the same question?

I work in a shop. I am around these bikes all the time.
Other than that, as Expatriate said, alu bikes were running 1.125" setups by 2001, and integrated headsets didn't really start to come into vogue until two years later.

Ya know, unlesss you know the specific bike, have that years catalogue or specs, you are still just guesssing.

Syd,

The original post siad that it was a 2001 Trek 1200. If Waldo works in a bike shop, he may actually sell Trek and actually know the information. Actually, his info seems spot on.

What I am getting at is that Waldo seems knowledgeable, put up his credentials, and gave sound advice. Why do you feel the need to throw out that he is guessing? I have seen you put out plenty of info on these boards on everything from components to frame tubing. I guess that you either A) have thousands of bicycles, B) have thousands of catalogues or specs, or C) are just guessing, if we use your logic.

Lighten up !

Lighten up !Read it again.....He sez..."I'll be willing to wager".... Now, do you want to risk throwing alot of money down a rathole based on that? Especially when the correct answer is so easy to get at?? And, FYI,Working in a bike shop is not credentials. Sydney is not into guessing. Are you listening??

So instead of passing on your wealth of knowledge, you elected to take the time to pick on me? That's pretty sad.
Seeing as I do know the specific bike and do have that catalogue (including specs), there's no guesswork involved. Thanks for trying, though. :p
The statement about wagering was made before I'd had a chance to check and confirm my statement. The only uncertaintiy on my part was making sure I had the right bike in mind-I find it difficult to remember the exact specs of every bike I've worked on or sold. Had I found I was in error I would have corrected it.
You're right-being around these bikes all the time, working on them, etc., doesn't really make me qualified at all. :rolleyes:

Now the standard size of the hangle bars journal has changed on the head stem :eek: what to do now?
Measure twice- pay once.
Velocity :D

Thanks, Ahctogi. It's funny the amount of misinformation on these forums that no one tries to pick apart, yet stuff like this goes on. Oh well, it gives me much to :roflmao: about.

You're right-being around these bikes all the time, working on them, etc., doesn't really make me qualified at all. :rolleyes:with all due respect to the few that might ,there are many that can't find their posterior with both hands. I always check the references first , so no wagering.

Always good to make sweeping generalizations based on a few encounters.
