GW, I think you could prevent that by keeping the thread, and the nutted end greased up, and with a washer between the allen head and the clampy bit??
….helpful suggestion, rather than crticism
I like them. they can be done up good and tight, and that does make a difference over crap OE skewers which i find are limited alot by the friction on the cam preventing them being done up proper tightly.
internal cam skewers (shimano type) can be done up just as tightly easily, and are just as stiff, but they are heavier (due to the lever) less secure (theft wise) and most of all, expensive!
ive got XTs on my Trance, which never gets left locked up unattended, and allen skewers on my Street/DJ bike and on my commuter.
i would put them on my trance for weight saving, but its a faff changing a puncture/putting it in and out the car (neither of which i have to do on commuter or DJ bike)
