    riding SID Carbon w/o expander plug?

    i have been racing on SIDs w/o star fangled nuts for three years now, but today i got a new carbon crown. does anyone ride his SID carbon without the expander plug? given that carbon is just as reliable as alloy steerers, that shouldnt be a problem, right?

    shoudln't be a problem although carbon steerers could be damaged from overthightened Stems. the expander plug supports the steerer in the clamping area to prevent any possible damage. . also carbon steerers are more "elastic" than Al-steerers. means they flex a bit under a load which might result in headsets loosening. i would suggest you use a Schmolke carbon plug to prevent any possible failure.

    i know several guys who ride without anything but i personally wouldn't do it.

    but congrats for the carbon steerer. that alone should save about 50g on your SID

    that's what i call a nice christmas gift.

    i'd sandpaper the clamping surface a bit and use loctite (the one that prevent screws from coming loose). we'll see....

    I've had bad luck with this setup

    I don't use a starnut or cap with my aluminum steerer SID, but I do use the expander plug and cap with the carbon SID steerer. I tried going without the cap on a ride the other day and the carbon loosened quickly. I guess I am also reluctant to get the bolts too tight with the fragile nature of the carbon steerer. For what it is worth, I am using a Syntace F99 stem.

    just finished my carbon conversion: exactly 1251g for 80mm travel+lockout. i still have Ti studs, so alloy studs might bring the fork below 1250g

    the carbon crown (slippery silver) weighs 490g for 163mm steerer tube length. the 2002 SID SL upper assembly weighed 526g. unfortunately less weight saved than expected

    anyways, this might be one of the lightest lockout forks out there i guess. dunno where else to save weight. maybe i could save some grams by replacing the long coil on the upper pure damper rod with an elastomer. or maybe there are some ti coils available....

    ... of course removing the air valve caps, the stickers and painting the fork black instead of white might save additional 8g, but would also make for a crappy looking fork :/
