Difference between road & MTB helmet

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Difference between road & MTB helmet

What is the difference between a road helmet & a MTB helmet? That may sound dumb, but most of the time when I look in the cataloges I can't tell what distinguishes them. They usually show the MTB helmets with visors, but those are removable, no? And why doesn't a roadie want to shield the sun?

A visor for one.

Also, I think they have denser foam? And maybe less airholes for more protection?

Heck, I don't know.

Visor gets in the way of your vision when you are in a more aero position...
More vents in the road helmet...

The visor on my Bell is removable (Bell even provides little plugs to fill the visor mounting holes), and has plenty of vents. Personally, I think that too many vents is just asking for trouble in a fall. To paraphrase Sidney, I'll take function over fashion.

By the way, no surprise, mtb helmets are cheaper too. $200 for a piece of molded styrofoam? KMA.

The difference is the size of the vents. Nothing else is different between a road/mtb helmet. The foam is the same because all helmets must adhere to the same crash standards.

There are also road helmets with visors, my Giro Pneumo has a visor and it's never blocked my vision when in a tuck.

I have heard that MTB helmets in the back. I guess this could be that you are more prone to falling backwards onto a rock mountain biking as opposed to road biking.

I have a Bell X-Ray MTB Helmet and it is the only helmet I have tried on that I like. Every other helmet makes me feel like a mushroom.

MTB helmets have the vents designed to keep you cool at low speeds. Road helmets are designed to be more aero and to have optimal air flow at higher speeds.

Road and MTB helmets are getting more similar these days, but there still are some MTB styles that you rarely see on the road:

$200 helmets have carbon and fit heads better in many cases. I bought the giro atmos at $140 off ebay because of its awesome fit on my head, its ventilation, colors, and tightening system.

the big difference is that the vents on mtn helmets are designed such that they discourage branches and such from poking into your head as you ride through the brush. hence the vents tend to be turned upwards.

road helmets, on the other hand, are designed to allow maximum airflow so the vents are turned forwards.

I have a really big head. My old helmet (Specialized L/XL) sat on top of my head like the cap on a mushroom. It seemed as if it would help protect my head a lot if I landed directly on top of my head (though my neck would break). If I landed on the side of my head or back, it seemed as if the impact would be shared by the edge of the helmet and lower part of my head - sure, it might reduce the impact somewhat, but I was looking for something more. I went to the LBS. The model I found that seemed to have the most protection down lower, and still have plenty of vents and light weight was the Giro Xen, which is sold as a mountain bike helmet. Unfortunately, it was well over $100. I waited and found a sale on last year's model and got one for $80.

I still have mixed opinions of the visor. I like it when it's sunny and I'm on the top of my handlebars, but when I have to ride awhile on the drops (like in a headwind) I find that I have to raise my head to see very far ahead. Luckily it's simple to take on and off.

I think it's silly to worry about whether a helmet is for mountain biking or road. Just buy what fits well, protects your head, has enough ventilation, and isn't too heavy. (Of course, if it makes you look really cool, that's good too.)

Oh, by the way, the helmet I'm wearing in my Avatar is one of those "sits-on-top-of-the-head-like-a-mushroom-cap" variety. I bought it on sale for something ridiculous like $9.00. I bought it just so I could glue a little rubber Goofy on it. I'm a 6th grade teacher and Goofy is my trademark character. I wear that helmet once a year when I take my class on a bike ride field trip.

My visor on my roadie helmet might make me geekish. But it is positioned in a way , I don't notice it in my aero position. I like every means possible to reduce road glare.

Ditto for me, haha.

I had a Lazer X3M mtb-type helmet when riding my hybrid, then I changed to a road bike, still using the samer helmet for awhile, and after 2 months I switched to a MET Estro road helmet. Strange thing is that the cheaper MTB helmet seemed cooler than the road helmet.

Haha..
