    Seriously for every study there's an opposing one and at some point a rebuttal. That's partly why the helmet debate is so difficult.

    But if you want 3 times the protection from a helmet the Kranium apparently is the answer and for much less money than the Hövding.

    And if what you really want is safer cycling work on reducing speed limits, getting cars off the road, educating road users to share the road, separating motor vehicle traffic, cycle traffic and pedestrian traffic at points of conflict, etc etc.

    Yes yet another tragedy and a result of humans mingling, unprotected amongst large infrastructure on the movc. That's not 'victim blaming' but stating a fact. Was the bike ride and risk so important in hindsight?

    But as an average cyslist, I don't and never have, demanded special treatment like dedicated cyceways. It is these demands that invite the fair question: Is cycling needed by the community at all and could we save far more lives with a bigger and better NHS and emeregency and rescue services for that kind of money?

    The fact is people don't need to cycle but have no choice with health and accidents and deliberate violence.

    As for me. Yep when a lorry or bus passes me within a few feet I know I shouldn't still be doing it but I'm too old to stop now.

    Would I encourage others to risk it? No; especially kiddies.

    Because a helmet reducing the risk or level of head injury *in the event of* an accident is not the same thing as reducing the overall risk of head injury to a cyclist.

    There are lots of reasons why this might be, including loss of the critical mass effect, risk compensation by cyclists, risk compensation by motorists, or change of the risk profile of the remaining cyclists (i.e. the cyclists that aren't put off by a wearing a helmet were the ones taking higher risks anyway).

    None of this makes the study bullshit, it's just a matter of understanding what the scope of a study is, and what conclusions you can reasonably make from it.

    I call complete and utter bullshit on that 'study'. As the entire academic world did on the Thompson-Ravera 'study' of twenty years ago, that gave us the zombie statistic that helmets prevented 88% of head injuries.

    If helmets work, why after NZ made them law with 95% compliance, did relative risk of injury *double*? Same in Australia.

    Also, cycling halved.

    Fight anything at all, from anyone, that says helmets are a good thing for anything other than competitive sports.

  • Anyone using Campag Centaur?1 year 3 weeks agoIt seems that most of us

    It seems that most of us agree; Centaur works just a little bit better than Veloce. I too have the Black and Red version and, to me, it looks a little better as well. In fact several people have congratulated me for upgrading to the red bolts. I just nod shyly and don't tell them it's all part of the package.
    Like you, Mr Clanger, I am sticking at 10-speed, for at least as long as I can buy the bits. If I can't get there with ten, what hope is there for eleven?

  • Deep Breath Everyone1 year 3 weeks agoI've been giving this some

    Waiting I've been giving this some serious thought... I think the only way to right this situation is to allow the deadline for the next race to run over by exactly one hour. Right now the deadline for the Tour of Flanders reads' Deadline in: 02d 15h 49m.' The right thing to do is to let the race start, let a breakaway get established and let everyone, including and, obviously, especially (!), northie, of course, to select the established breakaway for their team.

    However (!) Big Grin Road.cc should block! Big Grin I say block (!) the accounts of those who had the 'gall' to 'sneakily' and 'criminally' exploit the server clock error, namely Gkam, Ray and Wig Billy, and any other 'offenders' that can be confirmed in the next 02d 15h 49m to prevent them from making changes to their accounts after (!) the race has started.

    If you think about it, it's the only fair thing to do. Those of us who don't care will play the game without tampering with our selections because we see it fit to play that way Big Grin

    Those who want to play the game by selecting the breakaway will have a chance to do so and 'undo' the damage inflicted on them in the previous competition and 'repay' the 'perpetrators' with a dose of their own medicine! Big Grin That (!) is Justice (!) with a capital 'J'! I say (!) Big Grin

    You see, northie, what went wrong was not that they got the points, and you didn't (!) it was the fact that they got the opportunity to 'cheat', to play with knowledge of the breakaway, a knowledge that was not intended to be had because the race deadline is supposed to be before the race starts, and they took it (!). So I propose you (!) get the same opportunity, too! Big Grin To make things right for you! Smile

    On the other hand, maybe Dave should allow you (!) and just (!) you to pick the breakaway in the next race. Maybe you can email him during the race or maybe you can post your selection on the forum for all to see, like Gkam did, so that you, too (!) can get to experience the thrill G and Billy and Ray did, knowing you put the entire breakaway on your squad! Yippee! Big Grin

    You see, you don't get the points just because others did, you have to (!) be willing to do what they did, 'cheat'! Big Grin Wink

  • Cycle helmets have "major flaws" in safety, insists cyclist airbag firm Hövding (+ video)1 year 3 weeks agoCyclingscience: The title of

    Cyclingscience:

    The title of that paper, "Bicycle helmets are highly effective at preventing head injury" is more than a little misleading. Nowhere do they actually evaluate the effect on head injuries, rather they are evaluating the change in acceleration on head-form drops, and extra-polating that to what they think the effect might be on head injuries.

    A better title would be "Helmets are effective at reducing acceleration to the head, under the laboratory conditions regulations require helmets to be effective in". This isn't really new, we already knew these helmets do that. Note that, just as Hövding say, the accelerations they observed, 181g +, are still extremely high. You would not want be to exposed to these impacts, with or without helmet.

    The thing is that in the real-world, in population-wide studies, we do simply do not see anywhere near the same level of benefits of helmets. If the study you cite were correct in its title claim, there's no way the dutch (with their very low helmet usage rates) should be getting better safety than in the UK/USA - despite the slightly generally more unsafe conditions in the latter two countries. There's simply no way that injury rates amongst several groups in AU and NZ could have gone up /after/ the introduction of the helmet law, if they had such amazing real-world safety benefits.

    Controlled laboratory conditions with impacts and measurements that are /idealised/ to what helmets can do simply don't translate well to the real-world - real-world data seems to be very clear on that.

    It's likely that Hövding hasn't seen the most recent paper, published online in the peer-reviewed journal Accident Analysis & Injury Prevention, starkly titled "Bicycle helmets are highly effective at preventing head injury during head impact: Head-form accelerations and injury criteria for helmeted and unhelmeted impacts".
    The paper is by people who work in engineering, orthopaedics and biomechanics and who don't appear to have a vested interest in airbags.
    They conclude that helmets reduced peak accelerations in all impacts, helmets reduced head injury criteria in all impacts and, overall, helmets reduced risk of injury.

    We have known for years that this sort of study shows that helmets ought to reduce head injuries and deaths.

    We also know that the real life "experiments" in making cyclists wear helmets have failed to reduce the rate of head injuries and deaths in every country where mandatory helmet laws have been tried.

    Here is one example.

    http://rdrf.org.uk/2013/12/17/the-effects-of-new-zealands-cycle-helmet-law/

    It would be more useful to look into the disparty between theory and practice, in order to find out why mass helmet wearing does not have the expected result.

    To carry on doing this sort of study will not tell us anything about why some countries have failed to reduce their very high cyclist casualty rates by forcing cyclists to wear helmets.

    It looks like the numbers (HIC values etc) in this paper are similar to the ones Hövding quote in their video for 'normal' helmets, so they aren't saying that normal helmets don't work at all, they are saying theirs works much better. And let's face it, if you do hit your head you would rather be wearing a helmet than nothing, and at the point your face is heading to the tarmac you'd rather it was a massive puffed-up airbag than a little piece of EPS.

    Of course this is just more food for the helmet compulsion lobby which can't get past the notion that making everyone wear helmets would save some number of lives a year, to the likelihood that less people would cycle leading to more deaths by loss of 'critical mass of cyclists numbers', more deaths via obesity, heart disease, more congestion, more pollution (more deaths) and so on....

    The ideal answer still remains to reduce accidents
