Todays happy snap... me!

But for something positive to aim at -According to cycnews a rider from Skil-Shimano team broke his collarbone in the Ronde van Overijssel on the weekend & he hopes to be racing in 4 weeks!! :D

Are you being serious ????

The slight difference is that Helmets are designed to be DOA like that. Seat belts are designed NOT to break so you don't end up going through the windscreen.

Yeah why not. :) But feel free to not respond.

That's a good question. If the helmet shatters when you hit the car, what
happens when you bounce off and hit the road/lamp-post? Seat-belts are also
single use, but what would people do if, in one third of all crashes, the
belt broke during the crash? How much longer do you think that brand of
seat-belt would be allowed to be installed in cars?

I guess there has been a trade off in bicycle helmet size, bulk & cost to produce one that has some effectiveness but not a 100% solution to every scenario, read the link I quoted and what Franlkin says is his "ideal" bicycle helmet which covers just that scenario ( the second impact)...also on Motor Cycle helmets the force vectors statistically are different for the bulk of Motor Bike incidents so the more rubust and higher engineered helmet follows, but still lifestyle wishes for some have brought resistance to this too as commented on below by Henderson.

Henderson's study The Effectiveness of Bicycle Helmets:A Review Revised Edition Prepared by Dr. Michael Henderson for the Motor Accidents Authority of New South Wales, Australia.1995
[Reorder Number MAARE-010995] [ISBN 0 T310 6435 6] back in 95 covers some of this on M/B H's,
" Excellent evidence from all over the world consistently shows that bicycle riders who go without head protection are roughly three times more likely to suffer head injuries in a crash than those who wear a helmet. Further, a bicyclist who sustains a head injury is some 20 times more likely to die than a rider who suffers other kinds of injury.


But the notion that pedal cyclists should wear protective helmets was once seen as ridiculous. Helmet use for motorcycle riders was "different". Motorcycles were perceived as fast and dangerous machines, and crashing the bike carried a clear and unarguable risk of death or injury. Therefore, opposition to helmet use for motorcyclists has always been (in Australia) muted, and based on arguments for civil liberty rather than on the effectiveness of helmets On the other hand, pedal cycles have long been perceived as relatively slow, and falls and collisions merely inconveniences mostly suffered by children. The freedom to have one's hair flying in the wind was seen as much more important than the small risk of head impact if a rider was so unfortunate as to fall, or be knocked off the bicycle. But some twenty years ago, these perceptions started to change...."

as for seat belts... haven't seen one on a bike lately unless you mean in the bike trailers for kids (, dogs and groceries).

If you have a serious accident, and stress is put through your belt, insist on it being replaced...the law requires it, the unsurers know that..don't ***** foot on it. To compare car belts with bicycle helmets isnt doing apples with apples. Different force vectors again and different load application to different parts of the body, especially when one involves localised impact of a head and the other restraint of movement and inertia of a torso. I've seen the aftermath of broken seatbelts...it's not pretty...the aftermath of a damaged helemt is usally much better than the aftermath of a head without one.

Check out this graphic

In a lab test graphs of the impact energy the brain sees look like this, with a smooth curve extending over 6ms for the good helmet (on the left below), and a huge spike for a bare head (right).

Somewhere about half way up that spike is where permanent brain damage begins.

(see: http://www.helmets.org/general.htm)
 
All the best of luck for the op and subsequent recovery (and that x-ray is definitely going to be one to show to the grandkids!!).

It gets you sympathy too when you show people your helmet crushed liek
bug.

Yeah, it's like all those cars with the shonky crumple zones that just fold
up when you hit something. I mean, what if you hit a bus, bounce off and hit
a lamppost?
 
With this thread well and truely hijacked - looks like basso is in teh sh1t now.


Hope the op went well lama

I've probably done far more damage to my brain head banging over the years.

Mate that is courier like stats.

Just imagine, if you were couriering when you did that you would be getting paid to play playstation and sit at the pub.

All done. In today 7:30am, woke up around 8:30am. Done at the Epworth in Box Hill by Martin Richardson. A very straight forward operation with lots of friendly people along the way.

Happy snap: http://tinyurl.com/2zyexp

No more griding together of bones, very little pain (for now). They've OK'ed cardio work on the trainer... woot! I'll keep my feet up until the weekend though. 3 weeks until I can put any real weight on it, then I can ramp things up towards the 6 week mark where I'll be 100%. Yeehar!

I thought couriers were all sub contractors, so no work = no pay. Well
that was the case when I were a lad (in my very very brief stint as a
bike courier).

That's who did mine! Nearly asked, as mentioned earlier was pleased
with the outcome.

Helmets are designed to shatter on impact?
Are you being serious????

I'm sure many people would dispute that 'evidence'.

When I got my motorcycle licence helmets were not a requirement but were
advised. I had one but didn't wear it for the test as I wanted to be able to
hear the instructor's directions.

And indeed, they were.

No question. I would replace it.

Hehehe. So you think catastrophic failureof the helmet means it worked too?
Catastrophic failure of a crumple zone in a car means that there was
intrusion into the cabin. Helmets have crumple zones too, it's the
styrofoam. It stops being protective when it shatters. That's when intrusion
happens.
