  1. When I were a lad we had black and white telly, a testcard during the day
    and clockwork watches. Posh 5 speed racing bikes often had a mechanical
    odometer. It was attached to the front fork and counted each wheel
    revolution with a 'finger' attached to a spoke.

    Anyone know if it is still possible to get one? I can't be arsed with wires,
    batteries, tyre circumference, wireless gizmos etc. All I want to know is
    how many miles I've done since the last service, chain change, or in the
    last month.

    Errr... you would have to bother with tire circumference.
    I guess though they were all set to the common 700C wheel size.

    I remember one of these when I were lad also, I think it might have
    been on my brothers bike though.

    When I were a lad 700C was not popular in England, one had to choose
    between 26" and 27" on such clickometers.

    I remember those, and I think you're going to make things more
    difficult for yourself by trying to track down and use one.

    Cycle computers are one of the simplest and most fuss free components
    on your bike, worrying about "wires, batteries, tyre circumference,
    wireless gizmos etc" is really getting het up over nothing.

    You only need to set the computer up once, and that's it, job done,
    after that it will always just work. Perhaps change the batteries in
    wireless models once a year, every two years for wired ones.

    If you really want fuss free, then buy something like a Cateye
    Wireless. Look at the chart in the instruction leaflet which will give
    you a "near enough" number for the tyres you favor, punch that number
    into the unit, then zip tie one bit to your fork, one bit to the
    handlebar, and slap the magnet on a spoke. Finished.

    That will then give you speeds, averages, totals, just about every
    thing. How much simpler could you want it to be?

    They didn't have 26" wheels then, one rode on the road, not on mountain
    tracks, they were for the plus-fours brigade and sheep. The clickometer
    probably didn't need to know wheel size, it would be fitted with the finger
    at a set distance from the centre of the axle.

    You would buy one for the correct wheel size (IIRC). And it didn't
    matter where you put it with relation to the axle as it would only
    count circumferences of the entire wheel (much like a modern one.)

    I think Avocet used to do one that had a multi sensor arrangement on a
    ring, but that was a bit of a faff to fit to some bikes.

    A clickometer is much simpler. I don't need speeds, averages etc on my new
    Brompton. I have computers on my other bikes that do that and more. One
    thing that p*sses me off is those that lose track of settings when you
    change batteries.

    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.

    I seem to remember seeing one on SJS cycles (I think) but it's not there now, and anyway it was only for 24" wheels. They do have a mechanical speedo for £15. Thing is simple computers telling you how far you've gone and how fast you're going can be picked up for under a tenner, and really are fit and forget. As mentioend by others you'd still have to know your tyre size and compensate for that even with a mechanical one, most computers just have a simple setting, no need to measure anything.

    Technology is a wonderful thing, why not use it? :-)

    They had 26" wheels when I was a lad but they were simply for people
    who weren't big enough for 27" wheels. I would imagine that most
    odometers where calibrated for 27" wheels (but took no account of tire
    size). I recall one that bolted to the dropout and had a toothed cog
    that was driven by a spoke mounted widget. The distance of the widget
    from the axle is orrelevant since these devices counted wheel revs
    (just like electronic computers today) so the rollout distance (and
    hence wheel diameter) is relevant.

    SJSC have this http://sjscycles.com/store/item5997.htm which measures
    speed of the tyre carcass so wheel size is (pretty much) not an issue.
    Not sure if it is much less hassle than a cheap and cheerful electronic
    computer though

    Then you've got /two/ batteries to go flat, at different times. And the

    thingies.

    ME of similar things when I was little was that they are deeply [censored]. More
    hassle than an electronic computer, and drag too.

    And if you rode a roadster on the road you would have 26" by
    one-and-three-eighths, or 26" by one-and-a-half if you wanted to be
    unusual.

    I had one of those. Regularly got into arguments with people who didn't
    believe and couldn't understand why it worked on any wheel size.

    Load of rubbish, forever fixing the little red wheel so it didn't slip.

    I wouldn't fancy your chances of finding one calibrated for brompton
    wheels but ICBW. You could, of course get one for 27" or 700C or
    whatever and manually convert the distances.

    I have a 26" wheel odometer back in the bits cupboard. I can post it to you
    at cost. I imagine it's a 26 x 1 1/2 style 26" rather than a 26 x 1.5 style.

    Also, it has four or five hundred miles already on it, and it doesn't have a
    pin. But it's yours for the price of postage.

    We had 28" (my bike), 27" (most of my friends' bikes), 26" (my sister's
    bike) as well as 20" and various other sizes. I think the '26"' that my
    sister's bike had was a subtly different size than the '26"' that modern
    mountain bikes have, but I could be wrong. Furthermore, of course, we
    didn't just cycle on the road. We cycled where we were going, road,
    rough track, path, whatever.

    ....which would make bugger all difference since it still only clicks once
    per revolution and a 16" wheel revolves many more times to cover a given
    distance than a 28" one.

    Thanks Abrose, I may take you up on that . If I can find someone with a
    pin...

    Of course it won't be reading miles on 20" wheels, it might be nearer to
    kilometers.

    I had a few bike with 26" wheels before I moved onto the 27" ones. I admit
    that they were not as wide as MB ones but were about 1 and 3 eigths.

    I remember the speedos too. All the clocks were the same as was the cable
    drive. You just got the correct drive unit for your size of wheel - it had
    different gearing in it.

    Incidentally setting the "finger" at differing distances from the axle would
    have absolutely no effect as the wheel still turns one revolution to give a
    measurement to the unit and whilst the tyre travels faster than the hub
    relative to each other they are still only one revolution. (A bit like ice
    skaters linked together in a line - those in the middle are hardly moving
    but those at the outside are travelling very fast).
