Choosing a Road Fork
I have a 1995 Cannondale R600 and I need to replace the fork. How do you go about choosing one? I am unsure of current specs on the bike but I would like to get a similar fork. So any info on how to choose te appropriate length, rake, threaded or unthreaded etc would be appreciated. Any advice is welcome!!!
Thank you!!!

It will be difficult to give advice until we know whether or not the fork you have now is 1 inch or 1 1/8 inch.
My 1998 Marinoni road bike is a 1 inch that orginally had a threaded steerer tube with quill stem. I assume yours is also (?) based on it being a 1995.
I replaced that fork with carbon fork (Ritchey Comp) with a 1 inch threadless alloy steerer tube. I had to purchase a new stem, new headset and 1 inch spacers. The stem was a 1 1/8 inch with a shim to convert it to a 1 inch diameter for the steerer tube.
Total cost was $300 CDN.

I went to the local bike shop and had it measured:
1" threaded
Steer tube is 18cm
Crown to axial is 36cm
It currently has some kind of carbon fork on it though I have no idea what it is since there is no branding and the previous owner put it on the bike. I think I would prefer to go with a threaded system rather than converting everything over to threadless.
Thanks for your help!!!

If you want to replace it with another carbon fork with threaded steerer tube, you may be hard pressed to find one.
However, replacing it with a steel or aluminum fork with threaded steerer tube will be much more possible as there are many out there.
Going to a threadless system will be more expensive as you need new stem and spacers, but not hugely more expensive.
There are advantages each has over the other (threaded Vs threadless) but you'll have to decide your preference.
You'll need to know your current rake which is measured from the steerer tube centre to the axyle centre. Using a laser light (one of those laster pointers) position it in the centre of the steerer tube projected onto a table, measure from the laser light to the axyle centre will give you your rake.
