    Could you explain?

    Lord help me for saying this, but 'Daily Mail' types probably think
    cyclists all still use them, and those that don't have EverReady lights
    should be jailed.

    Think back to when frames consisted of 3 bits of 531 (or 18/23 on cheap
    Raleighs, which is probably some sort of gas fitting nomenclature) with
    depleted uranium for the rest; The cheap Raleighs etc had the rear
    stays soldered or Bostiked to the top of the seat tube, but with the
    flashy Carltons the two tubes were made as one piece and joined
    together by a small loop of steel that went over the top of the top
    tube. A few very flash Raleighs (who presumably owned Carlton) were
    made this way. I picked up a Carlton 531 frame at a boot sale a few
    years back, weighed a lot more than a modern 501 but at made a good
    £40 hack in the free ads paper a few weeks later ;-)

    probably didn't need to know wheel size, it would be fitted with the

    Of course they probably just assumed a 27" inch wheel.... Anything other
    than that was a kiddies bike and they didn't need to know how far it was
    to cycle to school.

    Eee when I were a lad I had one of those too. AIUI the wheel diameter was
    irrelevant to the function and so was the distance from axle centre and they
    weren't different ones for different sizes, because all they did was count
    the number of wheel revolutions, not the actual distance. To get the
    distance, if you wanted it, you had to multiply the number of revolutions by
    the wheel diameter.

    ???
    mine was even calibrated in miles; I think it was further than 6 wheel
    revolutions to my friend's house.

    ah just though of another bygone bit; those split links with a circlip
    type thing, my chain broke on way to said friend and a passing motorist
    just happened to have one. It was only after he repaired it much to my
    gratitude and drove off that I realised it would not go through the
    rear mech so spent the whole journey doing 3/4 pedal strokes ;-)

    old times, none of this new fangled decimal stuff ;-)


    The mechanical odometers weren't trouble free by any means. At high speeds
    they became unreliable, and eventually the gears inside wore out, especially
    if they regularly got wet. They got in the way when removing/replacing the
    front wheel (eg for punctures) as they were mounted behind the wheel nut,
    and then had to be carefully repositioned to work properly. You can get a
    cheap computer from Aldi or Lidl when they offer them (as little as 3 or 4
    squid), and ignore the info you don't want!

    Mine does. (The circlip is a bit bent though!)

    not strictly true; there were several common wheel (tyre) sizes;

    26 x 1 3/8" used for pretty much everything that wasn't a racer, still
    available into the 80's and probably still in India or somewhere

    These tyres are still available. I know because I put a new one on my
    back wheel a couple of months ago.

    Replacement brake blocks for rod brakes, you know, the ones that used to

    Cotter pins

    I need a new cotter pin for my left-hand pedal as the nut keeps
    working lose. I've heard of "cotterless cranks" but have never seen
    one. If I can find cotter pins for sale I shall buy two ..... so that
    I can chuck out the first one I try to fit after I've bent the screw
    threads whilst hammering it into the hole!

    From the content of this thread, it sounds like My New Bike [a
    mythical beast which may be a Brompton or may be a pannier-laden
    full-size tourer] will contain no parts I recognise!

    As a matter of interest, where in the world are you? Cranks using cotter
    pins are now vanishingly rare in the UK.

    I needed a new one recently, and the LBS said "I think we might have one
    out the back somewhere, hang on while I have a look". (They did.)

    (And my mechanical odometer isn't on the shelf I thought it was, nor
    in the next most likely box (I was hunting for something else), so I
    withdraw my offer of it for postage at least until I happen to come
    across it.)

    "Vanishingly rare" is a bit of an exaggeration - there are plenty of
    them still around. Oh, and be a bit careful buying cotter pins because
    there are two sizes and they're only a tiny bit different in diameter
    (6mm and 6.5mm if memory serves).

    I'm in the Wirral (UK).

    I got my bike second-hand off someone who'd bought it second-hand
    ...... so it's at least third-hand but I don't think it's *that* old;
    maybe late '70s, early '80s?

    Thanks Sandy. It's not urgent (although it only takes a couple of
    miles for the nut to loosen) so I'll have a look in the LBS and give
    you a shout if I can't find any.

    Coterpins were the bane of my young days on my raleigh grifter ... used
    to always end up with knackered coterpins .... I used to put it down to
    my strength but more likely to my lack of bike maintenance skills 😉

    ..... although I used to keep them tightened regularly - never really got
    my head around the problem.
