isn't the visor meant to take the first blow when you crash??

Visors are there to protect the rider from roost I  believe.

Pslide - the sketch you did looks quite cool though I can see where the Nova body kit comments come from. Not sure I'd want anything that's out of MAX Power stuck on my face.

I have to say, the D2 I have does give good ventilation but I do notice it on climbs, and I've noticed it more recently as my fitness slips into non existence. You're right about were MTB is at the moment, I'm not sure any major brake throughs will happen for a while though.

Look at gearboxes. Surely the perfect thing for all MTB applications, yet still very few manufacturers are taking up the challenge. Instead focusing on different ways of bending and shaping tubes.

If you can make a helmet proven to make a difference then I think you'd find a few world riders knocking on your door, but for joe public, the type of R&D you'd have to put in would no doubt make the unit cost out of their league. Don't give up on it, but don't focus on it, if you get me. I don't think MTB is ready for it yet.
its ok

i'm suprised troy lee hasnt snapped u up already

possibly a little bit of work could go into making that chin & mouth guard stopping the dirt and s**t going into ur mouth
Trouble is (directed at Pslide) you'd then end up with a compromise again, no better than what is already out there. As soon as you block it up to prevent cack getting in, bang goes your air flow.

Erm, did I say mountain bike company?  I meant bike company...  Roll Eyes

I arrived at the 5% number by comparing my red blood cell count from blood samples directly after doing runs with both full face and dirt jump helmet on.   Wink

Of course it's just a number out of the air.  Someone else with far more medical knowledge than me already posted a biomedical response.

Man, you guys just love ripping apart people's ideas.  I must admit, I've learned a lot about the SDH community from this thread...
One word of advice - don't go on dragons den then! It'll make this lot seem like a bunch of kittens!
Were we simply supposed to pat you on the back and congratulate you on an amazing fix to a non-existant problem?

I like how if you don't have the problem, then it must be non-existent...   Roll Eyes

It is interesting to me though that there are only a few people who have responded that have experienced the same thing I have.  Anyway, it doesn't have to be a big problem to be improved.  Otherwise we'd all still be riding single pivot bikes...

'Ere, isn't your bike a linkage actuated single pivot?! Don't slag em off, can't stand the way linkage bikes feel under you and I've never felt the single pivot of my Gemini or Judge hold me back.

Maybe Leatts and the like will bring about changes in helmet design as they become more popular?

I can see the next stage is going to be neck braces being compulsory when racing, it has already come into jnr mx, maybe not a bad thing with all the neck injuries happening caused by the weight of the helmets pulling on the neck

OT but are neck braces (the full leatt brace not the doughnut) compulsory in Jnr (presumably you mean school boy like BSMA etc) MX? I have seen a lot of kids wearing the doughnuts on practice days but only a few with leatts but I suppose the might only wear them for racing. Personally I quite like the look of the helmet sketch.

I highly doubt that to be honest. Unless the Leatt comes down in price by ~£200 they won't do well.  Overpriced b*lls**t if you ask me.

Leatts or a competitor will drop in price, no doubt. MTB specific full face helmets used to be hugely expensive and limited in choice. In time companies like 661 will have their own competitor, it’ll be much more mainstream, cheaper, and integrate better with their helmets (of course) – and probably with their upper body armour too.

This whole neck braces thing confuses me, was there / is there a massive increase in neck and spine injures recently?  I know there have been a few high profile ones recently but are there any statistics out there for this, like spinal injuries V's amount or riders / racers or avergage amount per season?

All feels very marketting led to me at the moment but then so did full faces when they started becoming popular. Think I'll go super hard core with a 90's style open face and Lycra setup (Mmm taste the gravel!).

Are you honestly being serious?  Doesn't even warrant a response really.

I don't know if there's been a big increase in MX/DH neck and back injuries, but it's more the case that the technology to help prevent such injuries has only recently been introduced on to the mass market.  Seems perfectly logical that with the speeds and track difficulty increasing in our sport that the protection should improve in accordance with it.

It's new technology, that's how it works.

The iPod was fecking expensive when it came out, now every buggers got one.  As demand increases the price will drop.

Well maybe, just wish i could afford an ipod! lol.

P.S original 5gb 1st Gen ipod $399 (10gb $499) - 16gb ipod touch $399 (32gb $499) 160gb classic $349. iPod's probably a bad example there still overpriced as an MP3 player.

Anyway my point was they would need to come down a bit to be mainstream as well as proving there worth and i dont just mean cost.

Wow, talk about the thread that won't die!  

Cookeaa, I agree with almost 100% of what you said, apart from the Nova body kit!  What design could be better than what I've drawn for directing air into the mouth area?  Right, maybe not aesthetically to your liking, that's fine, but don't criticize my fluid dynamics!  I got a solid B in fluid dynamics!  (10 years ago.  And I'm being sarcastic!)  Grin

To your first point regarding the evolution of DH helmet design, I don't really see a huge evolution from the MX helmet.  Yeah, our helmets are lighter and better ventilated, but they follow the same basic design MX helmet (for good reason - protection).  But with materials technology, I don't see why we couldn't have a total rethink of DH helmet design, considering heat management and air flow for cooling, exterior drag coefficient...the stuff you mentioned.  Look at the current peak design...we could certainly reduce the drag coefficient without any loss of functionality, and yet we are still using a MX design!  Angry

Dangerous Dave (trying to think who you are), I didn't mean to rip on single pivot bikes.  My point is that there is nothing wrong with the single pivot design.  They work perfectly well!  But that didn't stop people from thinking outside of the box and coming up with linkage designs.  Just like there's nothing wrong with the current crop of helmets (at least for most people), but that shouldn't stop us from thinking outside the box.

My bikes a Balfa 2-step by the way...it defies classification.  Smiley  Parallel link 4-bar perhaps.  Or "pre cursor to DW link".
