NYC XYZ said:Yeah, I get that impression. I hate how every goddamned tour and club
forces you to wear helmets!
As Steve Scharf suggests, this is probably about insurance. In the UK
various insurers have tried threatening cyclists with contributory
negligence claims when they've been injured while not wearing helmets,
but as yet none of these have been successfully pressed. The main
cycling organisation here, the Cycle Touring Club, has quite rigorously
acted against such claims.
Quoted message said:Hmm, I still can't really see it...is it maybe harder, at least, than
compared to an upright? To fall out/off.
Depends what sort of falling off. A sideways slide on gravel is at
least as easy, where flying over the bars is very difficult. On average
I find I don't fall off any sort of bike very often except a mountain
bike, and that's more a function of the terrain I'm not doing a very
good job of than the bike!
Quoted message said:No, that's what I'm driving at: surely in this 21st Century there are
"boutique" makers who do, I dunno, light-weight fiber-glass (whatever
-- I'm sure Materials Science is mature enough a field to be capable of
something like this!!!) that's cut out here and there for air flow.
Helmets will work by load spreading and energy absorption. The latter
will generally be far more effective than the former because there's
only so much head you can spread the load over, and the neck will often
take the whole lot at some point in any case. Polystyrene is actually
pretty effective as an absorber, but it remains the case that in the
sort of accidents that will get you killed it isn't good enough.
Helmets have a track record of not doing anything much to rates of
serious injuries in cycling populations, though I certainly wear mine if
I go mountain biking because I expect to fall off and at the sort of low
speeds the EN1078 spec is built to actually tangibly help. If you think
you'll fall off wear a lid to prevent a nasty graze and a headache, but
don't assume there's much chance of it saving your life.
Quoted message said:I know I'd pay $200, $300 for such a helmet! It'll be just as light
(or a few grams heavier, for Chrissake), or even lighter, and surely
stronger than STYRO-FOAM!!!!!!
Stronger in the sense of ability to break it in your hands, yes, but
better capable of absorbing energy? Unlikely. Most helmets made of
tougher stuff have quite a bit of absorbing material as well as the
shell, or have a fair bit of extra room and a cradle to spread the
impact (like a site or climbing helmet, where it's a pretty safe
assumption a primary impact will come from above)
Quoted message said:I'd rather not, but would since clubs and tours require it
Nothing stopping you organise your own rides, of course.
One thing to bear in mind with 'bents is they have rather different
performance characteristics to typical uprights. You'll typically be
slower up hills, faster into headwinds and down hills. This can be a
problem for all concerned if you're on a group tour on a hilly, windy
circuit, depending on how much folk are happy to wait up and take it at
a slowest pace. Lower machines can make life a little more awkward to
speak to folk next to you, and the fact that other folk can't draft you
can be an annoyance to some, though it'll depend on the group.
Something to bear in mind if you're into group riding though.
Pete.
