Another thing to bear in mind is you are talking about changing the materials used to something a bit more exotic.

Your average rider that is perfectly happy with their current lid isnt going to want to shell out yet more money for someone that isnt going to give an absolutly huge advantage.

They're far from daft, the left side of my face and head were totally saved couple of sundays ago coz of one.

I think the met parachute pictured at start of post is actually a good solution for xc riders who wana keep their teeth.

That's one thing that annoys me about this sport, people who knock people for riding or wearing whatever they like and feel comfortable in, live and let live, life's too short for fussin an fightin.

Dude, you might want to read the thread more thoroughly.  This isn't about not wearing a full face helmet, this is about how they are designed.

Yeah, more exotic.  Like carbon fibre composite or resin matrix.  Oh wait, must of us already are using that...  OK, yeah it would be pricey, but how much are people paying for Carbon D2s?   Tongue

The integrated lense would take some work to get right, but would snap out in case you wanted to use your own googles.  It's a pro option.  Remember when some pros were ditching their peaks to reduce drag?  Well the peak and integrated googles would hopefullly move things the right way...

Optional dust filter for the chin guard sounds good...may also reduce mozzie intake for the Scots...  Grin

Right, put pencil to paper 20 minutes ago and this is what I came up with.



Hmm, think I'll call it the Oxygen.

Featuring these stupendous, ummm, features:
 - Aerodynamic peak (similar to rear wing on F1 cars, attached in the center)
 - Optional integrated goggles with reduced drag coefficient (similar to aero helmets the roadies use)
 - Increased air flow to mouth and nose for more oxygen

Coming to a World Cup near you by.........probably never..........  Smiley

gr8t idea

all we need is 4 u 2 put into production Smiley

possibly troy lee will help u out or six six one Smiley

is anyone else seeing the "pimp my helmet" halfords spoiler/peak and corsa orimental bumper/chin guard there?

on topic a helmet needs to protect first and be cool second. i would most likely constantly dribble from one side of my face if it wasnt for my full face a few weeks ago.

and im using an older 661 and never had any real breathing issues when on the move.

aving glasses andwanting googles to hide them means I need a helmet with a little more breathing room.

My brother 661 just stemas everyrhing up whereas the Fox seems to have some more breating space and fogging is kept to a minimum.

any one who thinks that the met would not protect should know that all helmets are only tested to 17.5mph in a crash so no matter what helmet you have it has to protect you and they all will break at over 17.5mph even in spite of this i would probably still prefer and motor x helmet just because mine has save my head so many times

I'm sorry to say this, but that is b*lls

the CE EN1078 standard is the minimum safety specification for helmets sold into the European Union, and your information is based on that specification  Tongue

however, many DH full-face helmets substantially surpass this standard

specifically the Giro Remedy which is one of the toughest MTB full-face helmets on the market, and one of only a handful to meet ASTM F 1952 - the Remedy looks "oversized" and the reason for this is the thicker shell and thicker liner (foam) to meet the new standard which demands increased protection for the higher speeds and impacts common to DH racing


the ACU Gold standard to which MX helmets are rated, is another step-up from the MTB helmet in terms of impact energy absorption; this is why MX helmets are substantially larger than MTB helmets and often heavier, unless using multiple composites (which means a helmet typically costing £175+)


have a look at this:


Standards: Lab test protocols designed to prove that a helmet can manage impacts and has the necessary coverage and strap strength to perform well. Designers typically design to meet a standard but not exceed it by much. Bicycle helmets typically are certified to:

    * CPSC: the legally-required standard for any bicycle helmet sold in the US.
    * ASTM F 1952: downhill mountain bike racing standard requiring more coverage and more impact protection than CPSC.
    * ASTM F 1492: ASTM skateboard standard requiring four hits in one spot and more coverage but less severe impact protection than CPSC.
    * ASTM F 2032: BMX standard requiring more coverage than CPSC.
    * EN 1078: European bicycle helmet standard requiring less impact protection than CPSC.
    * DOT: US Dept. of Transportation motorcycle helmet standard requiring much more impact protection and coverage than CPSC, but sometimes met by BMX helmets.
    * Snell M-2005: motorcycle helmet standard requiring much more impact protection than any other in this list, and the only one that requires that chinbars be able to manage impacts.

the ACU Gold is similar to the Snel M-2005 for all intents and purposes

Congratulations on stringing a sentence together; unfortunately punctuation is required to class it as english.

sorry, but you said it was daft as the helmet designs have come from MX, but have put a visor on that, when a visor is to protect from roost, which, as you said, isn't a problem with downhill racing...
