    Carbon headset top cap - Reality Check Plz

    Quick, but strange question. Based on the photo, I'm assuming there's some sort of snap-in cover on the bolt head, covering the hex?

    A plug or cap sounds about right...

    There's also these. Purely Custom Online Store - 1 1/8" Carbon Threadless Headset Caps - Custom Bicycle Accessories

    I've got these on two bikes, simple and light and no problems at all.

    Great - cheaper and nicer than what I was looking for. Thx for the link!

    If you really want to go light...

    Go with these : Top Cap

    I got one and they're insanely light and hold on well. Expensive but that's the price of passion!

    Those Purely Custom ones are lovely - postage is a bit of an issue to England though!

    I always polish the decals off the CC ones and add an alu bolt:

    I'm surprised anybody here is running a top cap. I like to use a compression nut cap while setting the headset, and just take the whole thing out. No ill effects, and I'm 210 pounds. I'm looking down a hollow tube at the top of my tire.

    Heh... I'm the last guy on the planet who should be concerned with shaving weight, but I love a light bike (within reason).

    You won't find it so cool when that top tube punches a hole through your sternum in a crash.

    +17 points for correct use of the word "sternum".

    If you're running an FSA headset, this carbon top cap matches nicely. No ugly plug, either.

    ...Yeah pretty sure the stem will be in the way of that.

    Compress your stem and align bearings, steer tube and spacers using another stronger cap with your star and bolt.

    Set your stem.

    You can now remove star nut bolt and cap since their purpose is done.

    You can go with a crazy 3g Fibre-Lyte to keep the dirt out.

    While you are technically right (the stem holds the system together after the preload is set with the nut & cap), I'm not sure I'd want to ditch them to save a handful of grams. I like the idea of the safeguard it provides.

    If you crash hard enough you can spin the stem on the steer tube no matter how tight the steerer clamp bolts are, and without the star nut and top cap you're screwched for getting it realigned with the proper headset preload.

    .

    Bit of a dated thread, but I've been using a Cane Creek AER headset since last season. This is technically a road headset as the original "bearing" doesn't amount to much more than a a washer. Pretty amazing.

    I've substituted that bearing with a 40 series from Cane Creek which works nicely, and is recommended for mtn use.

    The cap is a bored out ALU, and while I haven't weighed it, I'll guess 3 gms max. (Also, the headset assembly itself has bored out "windows" to save weight. Don't think you'll find lighter in an XC platform.)

    Took an old chris king 9.5 gram top cap and shaved it down on the lathe
    to 4.6 grams. Including an aluminum top cap bolt, weighs 6.02 grams on my scale.
