    you are saying that he probably would have

    No, I'm saying he almost certainly did

    36.96 in an hour (return leg, no drafting, fixed gear) within the last year

    provided I can establish that they are flip flop (as the MK1 is)

    Mk1 was supplied in double-fixed or fixed-free more or less at random. I don't think anybody has ever died from screwing a single freewheel onto a fixed hub, so I wouldn't bother too much whether they are flip-flop or flip-flip :-)

    Doesn't fit the bill

    Why not? If the start and finish were on opposite sides of the road, he just has to trim the first and last bits to get a 1h segment with equal out and back legs, he only needs to pick up 0.1kmh on his average and the flying start should easily see to that.

    I don't understand your point

    My point is that there is not very much time to be made up by going faster when you're already going fast. If you're doing 110rpm on 50/12 (36mph), you need to add 4mph to save 10s in a mile. If you're crawling up hill at 12mph, you can save 10s/mile by adding just 0.4mph. Time trialling is not about going fast, it's about not going slowly :-)

    Count me as one of them, 25 miles (40.2km) in 59:25 last year with <1.5 miles between start and finish points. DannyAlf and @umop3pisdn both went quite a bit quicker on fixed, so there's 3 to start with, and @pnut went a lot faster than any of us. @Fixedwheelnut did 36.902 km/h for 25 miles, so there's a good chance he could pick a 1 hour segment where he did >37km. @xavierdisley was sub 2h for a 50 on fixed, so he must have easily done a 1h segment of over 40km

    The tubulars known to Europeans as 28" used to be called 27" over here, because you could use them in bikes made for 27×1¼ clinchers. A 28" clincher rim in English use usually refers to something now known as 635mm in ETRTO terms.

    spinning out on 50x12

    Do you mean spinning out, or just that you felt you could have gone faster on a bigger gear? Not sure what cadence you think counts as spinning out, but 150rpm on 50/12 is 50mph. You do know that you can only save 12s/mile by going 10mph faster than that, don't you?

    why do the Germans - of all people - have their own unique non-metric size for wheels (28")?

    I don't think they are the only people who use this terminology, for example Corima also use it, as do Vittoria. It's just an inch conversion from 700mm.

    CXP22 is really a bit narrow for 32C tyres, you should be shopping for at least 23mm wide, maybe even more if you're not planning to fit super-skinny tyres at any time. Mavic A319 would work, but if you have a bit of flex in the budget then Rosebikes have a good price on DT TK540 at the moment, which is a much nicer rim.

    Find I get more stress from riding busier SC courses like H10/2 and H10/1 than any DC course.

    I think the worst course I ride regularly is the H10/10, a combination of drivers doing at least 20mph over the limit on the bendy bit of the Drift Road plus getting in the way at all the junctions. H[10|25|50]/1 and H10/2 are nice and wide for the most part, so you can give yourself plenty of room without being closer to the centre than the edge
