  1. Many of you will know this, so don't read it.

    If you don't do.

    Black Ice is deadly because you can't see it and because it's
    unbelievably slippery.

    It is caused when below-freezing air, supersaturated with water-vapour
    hits something solid like the road. It forms an instant sheet of ice
    without the tell-tale crystals of frost, so you cannot see it.

    I had a terrible fall on it about 10 years ago, though no injuries.
    You fall really hard as the bike will be whipped sideways.

    Why am I posting this.

    Because a cycling Slovakian colleague, who should've known better than
    to cycle in really cold conditions, a man in his late thirties, broke
    the neck of his femur when he fell on it a week ago.

    My rule is, if you're going cycling and it feels REALLY cold on your
    ears, go home. Or check the temperature and if anywhere near zero, go
    home. Breaking your hip is a big deal.

    Not really an option when you have to get to work though. If everyone
    stopped doing anything because of this, that or the other then we might
    as well curl up and die. There's enough nanny-stating going on from the
    government, without having it here as well.

    For some people it might be a day to consider catching the train instead,
    or driving (cautiously, not spinning across the road and bouncing off
    a wall into cyclists, obviously).
    For others, going back home just for long enough to get the studded
    tyres out then off on the bike again. (That doesn't work so well if
    you are already at work and its frozen on the way home, of course.)

    I know Garry has had some run-ins on this NG in the past but be fair.
    He highlighted a hazard, noting that many may already be aware and not
    need to read on, and then said what his strategy for mitigating the
    risk is and why "/My/ rule" (my emphasis). I think you would be more
    justified in your response if he had suggested that everyone else
    ought to follow his example, but he didn't.

    There's a difference between saying "My rule is, if /you're/ (my
    emphasis).." and "My rule is, if /I'm/ going cycling..." etc.

    I have never had no alternative to the bike, but I would consider a
    tricycle of some sort if I really needed to keep cycling.

    Having said that I do cycle in the cold and not on a trike.

    Last weekend I was one of several in the club who had a scary moment
    on ice, but there were no falls that day.

    My only options are cycling or driving, or walking I suppose. Frankly,
    in cold and icy conditions I feel happier on my bike, although a lot of
    my commute is on cycle lanes rather than road, so less risk of sliding
    under a lorry. The only dodgy bit is that on one roundabout, cars come
    sliding around it way too fast straight towards the cycle lane.

    Yeah, right - and we've all got studded tyres to hand!

    freak accidents seem to happen to people he knows

    I broke my hip on a diesel spill - does that mean I should never cycle
    where diesel might get spilled? And should I post that here in the form
    of a rule?

    I had a spill on ice about 30 years ago. Just outside my house it was,
    bloody hurt I can tell you but although I couldn't continue into work
    that particular day it hasn't stopped me riding in the cold since. I
    just go a little more carefully. Paradoxically, roads are probably
    safer in these conditions than cycle routes as roads get "gritted"

    Ice is more common and predictable than diesel.

    I broke my hip by taking a bad line round a corner on a damp greasy road. I
    now take all corners more slowly and minimise the amount of cycling I do in
    freezing conditions.

    More common?

    Number of freezing days in a year?

    I have no idea but at a guess I would say about 30ish

    Number of Mondays when lorrys have overtopped their tanks and spill on
    the first bend.

    51-53

    Predictable

    Diesel on the road outside every fuel forecourt?

    I rarely come accross enough diesel or oil on the road to cause a slip when
    cornering at normal speed. I put it in the freak accident category. It's
    more common to slip on ice, IMO, and easier to predict which days will be a
    problem.

    In quantities and concentrations and places likely to cause problems for
    cyclists, yes indeed -- unless you don't cycle when it's freezing.

  17. I cycle to work. If it's icy I walk with the bike, and cycle home in
    the afternoon if warmer. I don't care if I'm late as I'm of no value
    if I've a broken hip. I'm the boss anyway so that's an advantage!!

    Black ice really is awful stuff. Hit it once in my car. Car spun
    totally around and I went onto the grass verge, pointing in the
    opposite direction. No damage fortunately, and I was not driving
    fast.

    I actually do no many people injured on bikes, and have known six who
    were killed. As some of you may know, I got a bad hand injury about
    4.5 months ago. I'm back cycling for the last couple of months and can
    cycle fine, though the hand will never be perfect. But, a minor enough
    ailment when you see what befalls some people.

    The point about skidding on ice is that you get a ferocious whack
    compared to an ordinary fall, as the bike is whipped sideways.

    Ice is more common and predictable than diesel.

    More common?

    Yes. Diesel spills affect one small section of road whereas freezing
    conditions can affect half the country on a given day. There would have to
    be an awful lot more diesel spills than freezing conditions per year for the
    probability of encountering a diesel spill to be higher.
