After experiencing outrageous frame wobble descending I searched the threads for some advice. I replaced my profile alum steerer tube fork with an all carbon 1" bladed fork and experienced the thrill ride of my life. Not all descents were scary but I got the bike to do "it" tthhhreee times on the same rollers. This maybe a test of how stupid I am, three separate rides before I switched back to the profile. I just returned from the rollers with my normal idiot confidence ( no violent shaking or need for new shorts ) Titanium frame + 173lb. rider + cheap fork = learning experience. But I like the people at our Performance shop.

It's not just the cheap forks. Replaced my Ouzo Pro all carbon with an all steel Kona Retro fork on my Litespeed Tuscany. Night and day difference. My big issue was brake chatter which is also un-nerving on down hills.
My front end is off about a half a degree now, but it actually handles better in all respects.
I'm not a racer which is why I decided to go back to steel and I'm so happy I did. Now my bike has zero carbon fiber and I'm very pleased with that.

Should note that my Litespeed was a 2000 model and the first year for 1 1/8" headtubes. Only fork available at that time was the Ouzo Pro.
