How do I upgrade Quill to threadless carbon?

[g7777777]

New to biking and have a couple of older Trek carbon frame but aluminum fork bikes -- I want to upgrade to carbon fork

the current fork are with a quill stem

I want to go headset and carbon fork

My models are a 2300 Trek carbon and an older 5200 Trek carbon

How do I do this? are the steerer tubes going to be 1 inch or 1 1/8?

feel free to post or email me

thanks

probably get more traction if you put this thread in the road cycling forum.

Quill stem road bike forks are always 1". To upgrade you are going to need: new fork, new headset, new stem (shim will most likely be needed - usually included with stem). Those old aluminum forks are very compliant so I doubt you will notice an increase in ride comfort with carbon.

Good luck.

first off, old trek carbon frames are sketchy at best. old carbon in general is sketchy. why not save a bundle, get a steel threaded 1" fork and call it a day? it will ride as good as a carbon fork, wont snap off in a crash, and with all the money you save you could get new wheels, and actually do something positive for your bikes handling. unless you are a monster sprinter, weigh 190 lbs or more and or ride these off road, threadless stems are overrated, non adjustable, ugly, and its impossible to find one in silver that doesnt cost 90 dollars and look like it was designed by george lucas.

what about the threaded carbon fork and just keep the quill stem?

any thoughts?

Threaded carbon forks are getting a bit hard to find. Nashbar has one for $130. The threadless version is $80. Same fork, as far as I can tell. For that price difference I would pick up a threadless headset and stem and go all the way.

why carbon? particularly on a bike of such dubious vintage? why spend the money? you could get a tange steel fork for a 3rd the cost, and it would be stronger, safer, and hardly heavier. carbon forks, at least 98 percent of them, have crappy tire clearance, so no fat tires, and no broken spokes allowed. by fat tires i mean easton forks dont even fit 25s... alpha Q forks barely fit 25s as well. thats not good design.
