I don't have a Bikinin Frame so not sure if this would apply to you, but I had an annoying squeak with my Timberline when I first got it, when it would get damp/wet. I must have a lot of side movement when I walk or something because no others apparently had it. But anyway, it seems that I have solved the problem by smearing a thin layer of scent free chapstick wax on the carbon stays where they go through any of the rubber-type sleeves on the pack. I'm not sure it's rubber (Aron could tell you what it is), but it feels kind of rubbery on the Timberline and apparently gets a little sticky and squeaky against the carbon when wet. No problems last week though after a couple of days of rain and no pack cover.
