    I have been on many Big Charity rides, with 3000 plus entrants or so, and
    everytime withing minutes I see riders to the side of tne road fixing a
    flat, and throughout the whole ride, I will see possibly 50 or so each time.

    Ok I just spent 3 weeks in Tokyo, and I would have to say that on any given
    day I would see 1,000's of cyclists comuting to and from work or where ever?
    However in my 3 weeks there, I never saw once anyone repairing a flat tyre.
    As silly at this may sound, it just intrigued me a little.

    Also I might add that cars & pedestrians treat cyclists with great respect
    in Tokyo, which is sadly not the case in Australia.

    The funny thing I saw was bikes getting parking tickets for parking in a no
    parking spot, but how do they trace the owners ?

    Maybe they just keep riding when they do get a flat...on the rims! The other thing could be that they are riding on bikes with heavy duty tyres.. thick rubber! (By comparison to standard roadie tyres).. but interesting tho..

    Prolly something to do with the huge quantity of broken glass - yobs using
    the road as their rubbish bin. Bring back deposit bottles. More littering
    fines and better policing would be nice too. There's also a s***load of
    steel belt fragments and other scrap metal on the road. Do councils still
    sent their sweepers* out? Lobby the b**tards!

    *Preferably with big magnets attached.

    Don't most weekend roadies pump their tyres of the morning before a ride?
    As they may only ride their bike weekly (or less frequent) they might not realise that they're looking at either a fast leak or a parcial leak that might be aggreivated with the next ride.

    With my limited expereince with v large group rides - like the 'Bay ride in Melbourne - there are many examples of tyres getting a top up before the start which leads me to assume that there may be a reason for the loss.
    Sure road bike tyres running over 100psi may call for a top up before heading out & a lot of us do that, but there are many sheds & garages about which house road bikes sitting squat on their rims.

    Rubbish is certainly a problem on many roads and bike paths, but I've been
    using a set of Vittoria tyres with built in puncture protection belt and had
    no punctures in two years of use. Lots of 'average joe' riders use low price
    tyres and don't know how to judge tyre pressure. Result is easy and frequent
    pinch flats. Often I've checked friends' bike tyres (not regular cyclists)
    and found that they have had as little as 30psi (estimated) in the tyres,
    but they say it's got enough air!!

    Do Tokyo commuters have a more accurate understanding of how to judge tyre
    pressure perhaps?

    Personally, in recent years I hardly ever have to use the pump on the road,
    with any of my bikes, because I normally use the track pump and pressure
    gauge before I leave home. Thank god for Silca.

    Cheers
    Peter

    The typical Tokyo commuter would not have a pump, would never have
    pumped up a tyre, and would never have oiled the chain. If a tyre goes
    flat the Tokyo commuter would either take it back to the store to get it
    pumped up, or would throw the bike away (I'm not kidding). As for chain
    lubrication, most bikes in Japan have full chain guards which helps the
    longevity of the shop lubrication, but it's very common to hear squeaky
    chains (and squeaky everything) on Japanese bikes.

    Most Tokyo commuters ride no more than 1 to 1.5 km at a time, and
    usually no faster than about 10 - 15 kmh. Bikes are many times more
    common than in Australia, and bike parking stations are everywhere.
    Some bike parking stations are even multi-storey.

    I've been the victim of a few "Michelin wires". There must be
    quite a few cars here driving with tyres so worn that the steel
    belts are exposed.

    Apart from those and broken glass, Tokyo probably lacks our
    dry-climate thorns (3-corner jacks), and the small sharp
    eucalyptus splinters crafted by mower blades.
