    Does it show up if you plug it directly in to a Mac?

    If you have an RCD any electrical fault that might lead to electrocution and death will usually trip the power without harm. I wouldn't want to live somewhere that didn't have one covering all circuits. This especially applies if you're prone to DIY or electrical tinkering.

    One RCD for the whole flat is just as effective as RCBOs. It just depends what there's space to retrofit.

    I think the middle photo shows a metal insert embedded in the carbon, with teeth to stop it rotating within the resin when the brake is applied / when the mechanic gorillas it.

    (Here's something similar on a carbon crank)

    The SE is a 6S chip in a iPhone 5 sized casing, and also worth considering.

    The 7 is the first one that’s fully waterproof*, which might be best for use outdoors.

    (* I wouldn’t trust it if the screen / battery had ever been replaced, or there was any physical damage)

    Volume of the tube is something like 4.8 litres.

    Atmospheric pressure is about 15 psi. If you inflated the tyre to "30 psi" on the gauge the internal pressure would actually be 45 psi absolute. By the ideal gas law you have 45/15 = 3 times as much air.

    Therefore a tyre contains 4.8 * 3 = 14.4 litres of air.

    (plug in your own numbers as necessary)

    AFAIK You can't chain these kinds of adapters like that. They work by telling the computer to generate an HDMI/DP/whatever signal and the adapter just provides the right physical socket. I don't think the "I want HDMI" message makes it across the MiniDP step back to the computer.

    So you need to persuade the Surface to output an HDMI signal, which I think it'll only do if you plug a direct USBC-HDMI adapter into it.

    The problem is the 4k 27 inch monitors is they're 1.5 times higher resolution in each direction (or 2.25 times as many pixels) as the equivalent non-retina.

    So you end up with displaying your desktop at either 0.75 or 1.5 times the non-retina physical size, neither of which is good. Or you use some ugly scaling to get it the same size.

    The 2012 rMBP can only run a 4k display at 30 Hz, which is not great. Plus to get a "retina" experience on a 27 inch display, you really need 5k resolution.

    I think you need a new(er) computer to get what you want.

    I'm assuming they work by altering the distance of permanent magnets away from the flywheel. I'm pretty sure that's how my panic-bought Elite Zumo does - you can sometimes hear the motor whirring when it changes.

    So if you unplug it the motor will stay in the same place and you still have resistance. Maybe there are some that do it eletromagnetically instead.

    I'd expect fluid and magnetic resistance units to stay at the same resistance setting when you disconnect power, so you ought to be able to continue using them as a dumb trainer.

    I doubt manufacturers encourage using them like this though.
