Need help replacing track fork
 

So I'm very new to this and dont know where to turn to! I own a Fuji Elios 2 (http://2009.fujibikes.com/Specialty/Track/Track.aspx). When I look at the specs it list the fork as being a Fuji 1 1/8" Custom Triple Butted Cro-Moly, crown. Now I was wondering if it a comprable replace would be the Origin8 Pro Pulsion Track Fork - 700, Crmo, 1-1/8 x 250 x 120. can anyone help me maybe get me on the right track on what to replace it with. any help would be awesome its getting nice out and i hate to let my bike rust.

Basically it's similar but seems to reference a threaded fork, while you need an unthreaded one.

For you the key specs are 700s with a 1-1/8" steerer, which also has to be at least as long as yours.
Measure your fork from the bottom of the headset to the top cap, that's the steerer length for comparison.

The other issue is rake, which is the horizontal distance form the steering axis to the hub's axle. I didn't find the rake spec in the description so that's something you have to ask about.

I took a moment to look up origina8 forks, and they seem to offer a 1-1/8" track fork with an unthreaded steerer. Here'a a link to their site
