Anyone else think the Catlike TT Helmet looks good? Similar, but different from the Giro Advantage. Any idea on price and availability in the U.S.? This would match the black/white P3 very well…
Not CPSC certified, so you can’t buy it from a store in the US. If you want one, you’ll need to order it from overseas and have it shipped over.
Not legal for USAT races, and will only be legal for USACycling races until the end of this year.
Why are they banned?
They’re not ‘banned’. They haven’t been approved.

politics…
What some consider to be politics, others would consider to be a better safety standard.

Specially in “standards” section look at the “Rest of the World”
It is not suprising to see the helmets standards we thought was not good for USA is actually better than USA. It is just government wants to do its own tests. The standards are from 1999 they have not been updated. have you ever seen a helmet from 1999?
I wasn’t saying CPSC was better than the all other standards in the world, but that CPSC is considered by knowledgable individuals to be better than CEN. A helmet that can pass CEN may not pass CPSC.
From helmets.org:
“The European CEN standard is less severe than the US CPSC bicycle helmet standard. Helmets built only to the CEN standard are less protective. One example of the difference is that CEN helmets are tested in 1.5 meter drops on the flat anvil, while a CPSC helmet has to perform at 2.0 meters. CEN helmets can be lighter and thinner.”
Look at the Giro Advantage - it passed CEN, but didn’t become available until modifications were made to get a passing grade by the CPSC testing standard - from the unsellable-in-US Advantage came the sellable Advantage 2. If you look at the two Advantages side-by-side, you can see that the 2 has thicker protective materials in it. I’m sure that if an out-of-the-box (CEN) Bell Meteor could pass CPSC as-is, then Bell would have had it on the shelves long ago.
One example of the difference is that CEN helmets are tested in 1.5 meter drops on the flat anvil, while a CPSC helmet has to perform at 2.0 meters.
This basically means that your head will be safer in CPSC certified helmet in the event that you fall onto a flat anvil from 2 meters up. Not many of those around here.
Different laboratory standards don’t necessarily correlate to better/safer helmets. Show me some crash test dummy impact/deceleration data please. That is why climbing ropes are all sold with fall/impact ratings issued from a standardized test (UIAA). This is shown on hang tags as the number of falls (as well as impact force to the climber) a rope can statistically withstand under a given load (80Kg for a single rope) until failure. Potential buyers can easily determine if they want to climb with a heavier/more resistant rope or a lighter/less durable rope. Or better yet, they can choose a rope according to the type/length of any given climb. Different ropes for different routes.
There is no way to compare helmets tested via two different protocols. Apples vs. Oranges. Period.
is that an autobot or a decepticon logo?
Testing data is a bit dry, they’re basically acceleration vs time graphs. The standards were drawn up to simulate typical impact energies in accidents against typical objects and attenuate the impact such that the peak acceleration does not exceed what is generally accepted as incompatible with life.
A flat anvil is to simulate a strike against the road.
It is possible to compare the standards:
http://helmets.org/stdcomp.htm
A line by line comparison of the test criterion shows the CPSC standard to be more rigorous than the CEN standard. CEN does call for a 250 G threshold vs 300 G by CPSC, however this is off set by the lower impact energy.
To put it into practical terms: a helmet that passes CEN may be able to be failed using CPSC standards by the lack of coverage or through higher impact energy on more impact sites/helmet; a helmet that passes CPSC it will also most likely pass CEN standards.
Between two helmets, I would pick the one that meets the CPSC standard.

I think Floyd was wearing one for the TOC prologue…certainly did not help his time any.
