    Please do put cap+bolt+star all on the scale, and then a "regular" cap/steel bolt/star set. It seems like a great place to save weight, if it works nicely in tensioning the headset. But knowing Extralite, any grams saved do come in a very special price/gram package...

    I'll do for him. REAL Topcap weight is 6 gr.+ 9 gr. Ultrastar = 15 gr.
    My OEM carbon Giant XTC cap weighs with regular steel starnut 26 gr.

    well heck, if you're going to shave grams that way, you may as well not even bother with the starnut, top cap and bolt! i'm sure someone makes light weight caps that can cover the hole if you're concerned with aesthetics. as for safety, how often has your stem come loose, or loose enough to turn and / or pull off?

    So how much did this 11 grams savings cost?

    It looks like Extralite has made the top cap and bolt a bit lighter since I got mine a few years ago. I have the version with a hollow steel bolt that weighs 8g (5g + 3g). The King cap and bolt come in at 18g, but half of that is the fairly long steel bolt. It would be very cheap to get that total down to around 11g with a shorter aluminum bolt.

    The Ultrastar is 9g, and a typical steel starnut is 10g. Not much weight savings, but it's nice to have a starnut that is easy to remove and won't rust. If you have a carbon steerer and have to use an expander plug, the Ultrastar is the lightest option. It's only drawback is that is can't expand enough to be used in some steel steerer tubes which have a bigger inside diameter due to their thinner walls.

    If you want to save more weight on a King headset, they offer a Ti crown race that weighs 8g. The steel crown race is around 13g.

    I just weighed my Chris King topcap with the standard head bolt and it came out to 17g. Starnut is probably 9g or so.

    I would like to have the CK TI crown race,but i am running a Pike 454 Dual Air on my Intense 5.5.So to keep the floodgate adjuster from hitting the downtube, i am running
    a Ventana 7mm crown race (weight 31gram)

    Or you could buy a short aluminum M6 bolt for $1 and remove some material from any generic cap and get the same result...
