Question re: helmets, and perhaps people like Tim would comment - is there really any substantantial differences, safety-wise, between the $15 Wal-Mart/KMart helmet and the $150 variety at your LBS? Aside from swoopy-do racing stripes/color/etc? My hunch is there isn't, as they all have to meet minimum safety requirements, but what say you experts?
I've never owned a Wal-mart cheap-o helmet but I regularly purchase my helmets off the last-year rack. USA Cycling, the US bicycle racing sanctioning body has a policy:
At all times when participating in or preparing for an event held under a USA Cycling permit, including club rides, all licensees who are mounted on a bicycle must wear a securely fastened helmet that meets either the US DOT helmet standards or one of the following standards:
(1) American National Standards Institute (ANSI) Standard Z90.4;
(2) Snell Memorial Foundation Standard "B" or "N" series;
(3) American Society for Testing and Materials (ASTM) standard F-1447.
(4) Canadian Standards Association (CSA) standard CAN/CSA-D113.2-M;
(5) U.S. Consumer Product Safety Commission (CPSC) standard for bicycle helmets;
(6) European Committee for Standardization (CE EN1078) standard for bicycle helmets
Helmets which meet this standard (so printed inside the helmet, usually, on a sticker) should all be equivalent, safety-wise.
I can say that if a helmet does not fit you properly or is not worn properly (level, not too far forward or backward), and snugly, it's not going to perform to its rated ability.
I bought a 1-year old Giro off the REI clearance rack once for $29. That's the least I've ever paid. Sunlight and heat destroy, over time, the structural integrity of the helmet, so you should keep them out of the heat and UV when not in use, and get a new one every 2-3 years or whatever the manufacturer recommends. I wouldn't buy one that was more than a year old.
One other tip - some manufacturers have (or had) a crash-replacement policy. In some cases, they use the crashed helmet (and in Paradox's case the photos) and details for quality control / improvements.
The main differences with the more expensive helmets are:
- Superior adjustability
- Better ventilation
- Lighter weight
