    Looks as though the latest Boeing and Airbus planes won't be grounded if it rains...

    Do you know what you are talking about? Because I heard these things for the first time last week from a scientist collaborating with Boeing, among others... the problem is still very much real, in the aerospace industry

    Of course it won't 6 wheels, and it won't be allowed to fly unpainted either... there is a lot of technology beside CFRC in a Boeing 787 fuselage... for example... did you know the all structure needs a copper mesh to discharge electricity in case of a lightning strike? As an average every plane gets hit once per year.
    Without the copper mesh the structure is likely to overheat and melt as CF is not a good enough conductor

    Don't hibernate it, ride it.

    I ride my best bikes all year round no matter what the weather

    If you need to hibernate it I would
    *leave tyres inflated
    *clean bike & re-lube (preparing for your next ride)
    *spend many hours drooling over it and dusting it down
    *get out for a ride on the 1st dry day available

    I know a little about carbon manufacturing but not how it would be manufactured for aerospace use.

    So who do you work for out of interest?
    My winter bike is exactly the same as my summer bike,,, but dirty...

    The point made is that the statement: "carbon fibre doesn't like water" is not completely hollow. It affects the glass transition and can lead to minor warping and bubbling... then make what you want of it... I don't think it's the case to rush and panic... this stuff was known in the 1960s, well before carbon fibre got into bicycles

    Carbon Fibre, like Wood, can soak up water. Carbon fibre is used extensively in the boating industry where things are expected to get wet, so they're made/treated accordingly.

    Do you think your bike is any different?

    I would be concerned if the frame had exposed CF, but then I'd be concerned then anyway.

    You mean like the wheels I was talking about?

    I'd get the bike into a position where I know it doesn't require an additional service, i.e. it is ready to rock when the sun comes out in the spring.

    In my case that would mean:

    Check cables for fraying in shifters or at clamps and replace if needed
    Flush through the cable housing runs with silicone spray, GT85 or WD40 at a pinch (I'd prefer to avoid the WD40 though as it will gum up over time; the other two do not use mineral oil as the lubricant)
    Oil the derailleur pivots and limit screws (only to stop them seizing up, not necessarily because i'd want to adjust them)
    Fully inflate the tyres and make a note to regularly check the pressures throughout the winter
    Check wear indicators on brake blocks
    Clean wheels with hot water
    Check wheel bearings and freehub bearings and service if required
    Check spokes for tension and correct any that are loose
    Check BB and service if required
    Clean chainset
    Thoroughly clean and oil chain
    Check seatpin for seizure, remove & grease

    That's my end of season service.
