Road Cycling - recommend a carbon fiber fork

I want to buy a decent quality carbon fiber road fork. It should be fairly light yet durable and definitely not too expensive. Used is fine. Does a used carbon fork deteroriate over time? 1" threaded...? How much heavier is threaded vs threadless?

Thanks :D

carbon forks are definily much heavier with threaded steerers beuase you cannot make a threaded fork's steerer tube out of carbon. for carbon steerer tubes, I beleive that the 1'' unthreaded is about the lightest you can go. I would not buy used. Carbon is very strong, but it is difficult to see any damage that may have occured on a carbon fork used by someone else.

From my studies on the internet the Wound-Up brand seems to be the strongest but not the lightest. Maybe someone can correct me it that's wrong.

Mixed reviews on Wound-Up.
I like the Reynolds Ozu Comp ( or whatever the alloy steerer model is named).

Kinesis makes a cheap carbon/alloy steerer fork. It's basic but it is reliable, and inexpensive.

Profile Design has some cheap stuff usually threaded and threadless offerings

LOOK HSC.. the best CF I have tried yet... But I don't beleive they make it with threaded steerers.. these fork is all Carbon..

If you go threaded, you give up most of the weight advantage of a carbon fork. A new headset and stem will add about $100 to the total cost.

I have this one, good price, Profile Desing BRC http://www.performancebike.com/shop/Profile.cfm?SKU=16749
