    living in a coastal area

    Move inland 🙂

    Actually, just move the frames indoors. The garage has too much exposure to sea spray and too much diurnal temperature swing, so you're bound to get condensation and corrosion. In the living room, the swing will be less. An internal spray of Boeshield T9 won't do any harm, but is not necessary for frames which are laid up in the right conditions.

    long term

    How long? My experience is that normal domestic living conditions are fine for at least 70 years.

    Any reason why I shouldn’t just chuck them?

    They are there to stop the pads coming out of the back of the holders in case of reversed braking load. Although this is an infrequent occurrence, the sound of padless holders contacting your rims is not quickly forgotten.

    Do you think it’s safe to ride on?

    I think it will get too annoying to ride before it becomes too dangerous to ride, after allowing for your risk tolerance which let you ride a 20 year old plastic wheel with a dubiously designed boutique hub before you realised it was broken 🙂

    If it really is a de-bonded flange, the terminal failure mode is the flanges getting closer together as the carbon barrel wears down by fretting. This makes the spokes go loose and maybe the bearing cartridges walk out of the flanges or along the axle, depending on how they are retained. As it wears, the compressive stress on the barrel actually goes down, so exploding into carbon fibre shrapnel is unlikely. If the bearings are fully constrained without the barrel existing at all (this is a possible design), then as the barrel fails the preload on the bearings rises, and eventually they break, wear out or just squeak so loudly that you realise you're not cursed by a constant imperceptible rising road but by massively increased bearing friction.

    should that be 'slippy' or is 'slippery' used as well

    Slippy is informal or dialect, slippery is standard English.

    I do not know this tandem

    It's in the post immediately above your Serotta

    Do we know if Vic acclimatised in Mexico or did he do the fly in at last minute thing?

    I read that he acclimatised at an effective 3000m overnight by using a hypobaric device, and when he wasn't in that he was at the actual 1800m of Aguascalientes for at least a couple of weeks.

    Would Wiggo have got Boardman's at altitude?

    Xav's your man for that kind of analysis, but my back of a fag packet calculation suggests that he wouldn't, unless he was well up the favourable tail of the bell curve for response to altitude.

    Campanaerts must’ve been averaging something like 400

    Assuming the same Cd.A as Wiggins, going 1% faster with 17% less air density suggests that 370W would be in the ball park. Depending on how well his power holds up at altitude, that's like doing 400-420W at sea level.
