This Is Your Brain - Composite Fusion and Helmet Shells
@KaliProtectives: I would love to see the real graphs. I have an issue with the one published. Saying impact energy is measured in Gs is not accurate. It's measured in joules. Sorry to be picky, but I get annoyed when scientific terminology is used fast and loose. Really this is a force/ time graph and you are assuming that both curves are acting on an equal mass, thus equating deceleration to force, which is fine in this context. Here is my issue. I think the area under under each curve should be the same, as this is proportional to change in momentum, which should be the same for both impacts. You claim your product reduces the peak force acting on the mass being decelerated (the whole point of your product), therefore the lower forces must act for a longer duration. Your simplified graph does not convey this.

The EX Enduro 2016 - Recap
Brilliant! A very British affair by the looks of it. Makes me yearn for the camaraderie of racing again.

Orange clockwork 29er

$550 GBP
Excellent xc bike, but surplus to requirements. Has not seen enough use to justify its place in the fleet. Frame is in good condition with just a couple of minor scuffs. New shimano deore brakes, slx mech, zee shifter, deore cranks running narrow wide chainring so you have a reliable 1 x 10 set up here. Superstar wheels and maxxis beaver tyres. Gravity bars 780mm wide and stem is 50mm long. Really nice cockpit that I was tempted to swap out before sale. Rock shox recon forks with maxle. Air sprung with the steel stanchions. A very light bike that climbs effortlessly.
