what are you lubing the top & bottom bearings with? ICON says "no lubrication required", naturally.

they are supposed to be Teflon-lined. then again, the knock against ICON's UCAs used to be that the uniball was Teflon-lined COM10T—before they upgraded them to stainless steel.
anything else you've been doing to protect your ICON gear? i wish i'd installed a set of rubber shock boots on my rears when i put them in. i have the shin guards, but still... oh well, i don't feel like fussing with them now. maybe come spring/summer next year.
