1)What helmet do you use?
Giro Rift
2)What did you pay for it?
About $50
3)And when/what will make you decide to replace it?
It takes a hit, gets to funky, or I find something lighter/cooler that I like to justify the cost.

1. Bell Influx.
2. About $40.
3. When cars are no more (it stays home unless I'm on a group ride that requires it)....

Bell Muni Bicycle Road Helmet

$55.17

A few years

1) nutcase urban warning design with extra reflective stickers.
2) about $50
3) I'll buy a roadie-looking helmet for more casual riding as soon as I find a good deal. My wife hates the stupid-looking nutcase, but I will continue to wear it for commuting.

1) Bontrager Convert (ordered and will be in my hands in a few days)
2) 50 euros ($71)
3) If it doesn't have an expiration date (like motorcycle helmets do), I'll change it when it starts to show it's age -or- something more comfortable becomes available.

1)What helmet do you use?
* Specialized S-Works Prevail

2)What did you pay for it?
* A Staggering $229

3)And when/what will make you decide to replace it?
* When winter rolls around I'll be ordering an additional helmet with integrated ear warmers.
* And when 5 years pass, or I crash and the Prevail takes a hit.

1. Bell Metro with rain cover if it's raining; Specialized S-Works if it's not.

2. Metro: about $60, maybe. It's been a while. S-Works: $120, half of msrp because I had an inside line.

3. When they crack.

1) Specialized something-or-other.
2) ~$30.
3) When it's damaged (so hopefully never).

1) Bell Metro and Giro something

2) $35/ $3 ( purchased at a flea market- in box, unused)

3) Will more than likely replace the Bell Metro this winter with a similar model.

1. Bell Faction
2. about 40$
3. When it breaks or I have enough money for: http://www.gathsports.com/productsingle.php?id=2

I know it's not a bike helmet but I'd really like a retractable visor, I have a fixed visor on the Faction.

Ditto, like the 6th time or something.

As my wife says: "Helmets are sexier than head injuries". I'd have to agree and state they are more comfortable as well.

Giro Hex - nice venting and doesn't look like I'm tryin' to be Lance.

About $30

I'll replace it when Giro will stop sending me new pads... I go through them like crazy. I'm looking into a multi-sport helmet for commuting though.

Those who use multi-sport helmets; what made you go this route? Aesthetics? Function? Comfort? Price? They look a bit more durable as far as day to day scratches and the like go. Do they vent decently? I don't worry about aerodynamics at all, and hate the way heavily vented helmets look, but I sure do like the airflow when the temps break 100F for weeks on end with high humidity.

A Schwinn cheapo foam hat.

Yard sale for 3 bucks.

When it breaks or my ego causes my head to swell to the point where it no longer fits.

Giro not sure of the model
Bought in 2000 when I was in college.
Prolly paid $40.

I crashed once, but missed my head. Still at 11 years I will replace it this winter.

Bell something or other for $40 to replace the one that "wore out" a few winters ago when I headbutted the concrete pathway after hitting a patch of ice.

I bought a $20 Bell from Walmart yesterday. I was in a motorcycle accident at 55mph a number of months ago, helmet saved my freaking life. While I wholeheartedly believe these things are goofy looking, you won't see me ride anywhere significant(read: outside the neighborhood) without one. But I'll never be able to justify spending more than 50 bucks on a helmet.

I'll replace it when it gets raggedy, nasty, or broke.

The helmet: LG Titan carbon.
Cost: Nothing. Got it from my brother earlier this year when he was getting out of bicycling and I was getting back in.
When to replace: next spring or so. It was made in '06, so it's about at the end of its lifespan.

Hah. You think replacing a bicycle helmet is expensive? Take a look at motorcycle helmets: same replacement timeframe (about 5 years or less) and cost from $150 to $800 or more. I stopped feeling quite so bad about gear costs for bicycling when I got into motorcycles. ;)
