A 125mm threaded steerer is very short. It probably won't fit..I ride smaller frames than you and a 125mm steerer wouldn't fit on most of my frames.
In addition to headtube length, you also need to now the stack height of your headset.

Ok...
The next question is does the frame actually use a 1 inch threaded steerer and a quill stem? To figure out the necessary steering tube length, measure from the bottom of the headset to the top of the headset, if it's a threaded type.
If it's a threadless type, then you have to measure further up, to the top of the stem.

The short answer is no, it's not long enough.Jeepson33s said:

its a quill stem. would i just be better off going to a threadless and getting a headset and stem, would i be doing anything worthwile? i have an aluminum or chromolly fork and its brutal but the frame is so smooth and tracks well so i think that the weak link is in the fork. any insight would be great.
go threadless...
I would highly recommend going threadless, if you're going to spend money a new fork. If you shop around, you may still find a bargain fork on e-bay. Of course you can always get a new fork with a 1" steering tube.
Performance Bicycle has a package deal on a fork, stem headset and spacers for $150-$190. http://www.performancebike.com/shop...tegory_ID=5232&CFID=14288774&CFTOKEN=57361962
If you measure the height of your handelbars, vertically from the ground to the top of the bars and measure the head tube, without the headset, I can give you a pretty good idea for a spacer and stem angle combination to match your current setup.
My only other warning is that a carbon fork may not work miracles. I read a lot of claims that forks are responsible for various ride and handling problems. I have a hard time believing all them, because it's tough to separate the contribution of the frame from the fork in the ride equation.

what about this fork, 165mm steerer, possibly long enough or is that pushing it?

Profile Design Carbon Fork
I have a 56 cm Specialized Allez Epic. I bought it used with the original aluminium fork and finally replaced it with a Profile Design BRC carbon fork. It was the best thing I could have done with this bike. It virtually eliminated high speed chatter and hash, and made riding centuries a pleasure.
An unexpected benefit was the increased top speed on steep downhills. I went from a max of 44 mph to 47 on 2 specific hills that I rode frequently. Control at all speeds is also better with the carbon fork. My shoulders aren't sore any more from extended rides either. :thumbsup:
This is my winter bike now, but I'll ride it until it won't ride any more. The Allez Epic is a sweet carbon bike that never received it's due.

I agree with Carbonman; I've had a 56cm Allez Epic since 1991 (FYI headtube length is 150mm) and found that while the original fork handled really well, the ride was brutal. Replaced with a Look fork with threaded steel steerer and carbon blades - much more comfy!
