Headset keeps going loose

I have a felt f1 carbon with an Easton ec90 slx carbon fork. I have only been on three rides, but every time I go out I find that the headset has come loose. The rides have all involved a screeming decent down flagstaff mountain road and this requires alot of front break. I have zipp 404 wheels and 05 zero gravity breaks. I am using the cork pads but the breaks are real strong and can be a bit graby, do you think they are to much pressure for the clamp bolts of the stem and it ends up working its way up the stear tube? The stem is an FSA carbon and I have tightened it as tight as I dare. Do you think the problem could lie in the stear tube?

you need the problem solvers fork compression plug, excel has it for 16 bucks. they note in on the site that it is goos for easton forks, they seem to not have a normal inside diameter, i just got mine from ups about 10 min ago.

Or one of these:

I'm using one on an Easton EC90 SL and it's perfect. There's an aluminum cap that fits into the steering tube that supports it against the stem clamping force; VERY secure.

Price is right, too.

This might be a possibility too.

Thanks for the segetions, great price on that compresion cap at supergo. The problem may be that the 5mm space between the top of my stem and the steer tub is to small and as I compress my compression plug it ends up hitting the steer tub. I thought 5mm was enough space but I will try a centemeter tonight and see if it improves.

Thanks!

...or install a thin headset spacer at the bottom before shortening your steerer tube to see if that corrects your problem.

Near the bottom of the Park Tool instructions ( http://www.parktool.com/repair_help/...readless.shtml ) it shows the gap between the top of the steerer tube and the top of the stem as being a couple of mm. The plug is supposed to go into the steerer tube and not on top of it, otherwise you wont be able to pull the stem down onto the bearings. Get a thinner spacer, so you can get the stem clamping the steerer over most of the height of the stem.
