Summary Research into brain injuries has been ongoing, but tended to focus more on direct impacts. In the last 70 years there has been more research into rotational brain injuries, and in the 1990s and 2000s scientific, evidence based proposals were made to reduce these. The Multi-Directional Impact ­Protection System is an implementation of these, and it's ...

A recent study investigated the impact performance of 675 used helmets (some as old as 26 years) without signs of damage. (They collected 1500, and eliminated helmets with signs of damage). They all passed, except four. Three that failed were only made to meet the old ANSI standard, and the only newer helmet to fail was a recalled model. Because all of ...

You can make your own retention system for any bag which will hold the helmet secure and close to the bag. I've done this on a number of my bags as I carry both bycicle and climbing helmets at times and there is never enough space for them inside a bag as they're such awkward shapes. Buy some elasticated cord (often called shock cord) and some cord locks ...

Short answer: they're not required to. According to http://www.spkids.com/pages/astm-helmet-safety-standards-explained this standard consists of these tests: Dropped from two meters on flat anvil (iron block); drops from curbstone and hemispheric anvils placed higher than bicycle helmet testing Three anvils mimic various mountain bike terrains for ...

The technology is called hydro dipping or water transfer printing. A quick search will find several companies that do it. I would expect you can find one that handles the production and shipping when you provide the design.

According to UCI's official regulations Section 1.3.031 (emphasis mine) Wearing a rigid safety helmet shall be mandatory during competitions and training sessions in the following disciplines: track, mountain bike, cyclo-cross, trials and BMX, para-cycling, as well as during cycling for all events. During competitions on the road, a rigid ...

I have used some half-inch thick strips of foam to help raise the helmet You need to add the foam where there is a void between your scalp and the helmet. It should not be added where the helmet presses on your head. Small amount should not mess up how the helmet works. Its no different to going from a long haircut to a short haircut. In winter I wear ...

Following the advice of those who commented: I came upon this solution. Cut the access length (about 1 cm), leaving enough for adjustment Melt the ends of the straps with a torch Use electrical tape to wrap the ends tightly so they resemble 'method 1' but without the excess length.

Helmets are one of those pieces of equipment where you want to err on the side of caution, keeping your head in good condition is high up on the list of priorities. Personally, I wouldn't be able to trust a 'test' helmet. Even if it looked okay there's a strong possibility that someone, somewhere along the line, dropped it, and it could potentially be ...

Answer: Yes - anything on your helmet may affect its ability to function. Remember the skiing accident that gave Michael Schumacher brain damage? http://www.telegraph.co.uk/sport/motorsport/formulaone/michael-schumacher/10640839/Michael-Schumacher-skiing-crash-did-helmet-camera-cause-head-injuries.html That was not cycling, but he managed to run his ...

I sweat easily and am in shape however I do the following (and this may repeat what others have advised, while the difference is, I do it daily an experience it - I am in Toronto, so the weather is also getting warm): I currently ride in jeans and t-shirts (see below).. I ride where my body temp doesnt get too high...its very tempting to race or keep up ...

Bicycle helmet is to protect the head, which has the most important organ in human. You could still live a normal life even with broken/ lost limb(s). But a head injury could change your life forever. A helmet is like a wall between life and death. The priority goes by protecting the most important thing to you first (i.e. your life), not by preventing the ...

I would suggest following - try to clip helmet chin strap around both backpack shoulder straps or, if backpack is not too big, try to clip it around whole backpack. (If your backpack is large enough you can put helmet inside it :). There is also possibility to use rubber strap with hooks to fasten your helmet. Tbh, I have backpack which has dedicated ...

Wadelp's post is the correct one -- the pads add nothing to crush/impact damage. There is one factor that is worth considering and that has recently received more attention -- especially in the sports world -- and that is twist damage -- also known as rotational or shearing damage. That is, if you get a glancing blow from an object or if you hit the road ...

A motorcycle helmet will be too hot and heavy for cycling. Spend $20 USD and get a cheap bicycle helmet - you'll be a lot more comfortable and happy.

I think you are concerned with the 'rate of degradation'. I've designed sports helmets recently that use similar materials (EPS for example), but not for so long as to ascertain all aspects of durability. Your biggest concern would be loss in mechanical strength on photodegradation. The rate of change in the mechanical integrity of expanded polystyrene (...
