I'm sitting here having just ordered my second Gyro Hex helmet. I'm typing with a broken bone in my elbow and a cracked rib, but thankfully a fully intact skull...
Living in Seattle we have a certain amount of rain, this summer slightly less so. So a couple of weeks ago on my way into work I wasn't paying proper attention for a rainy Monday morning ride, hit a slippery patch on a corner at 15-20mph, my bike flipped and my 190lb self ended up plummeting head (and elbow) first into the asphalt...
I have never been so glad of a helmet in all of my life; it totally absorbed the impact (all be it by cracking into four parts, as expected). The actual structure of the helmet stayed together and gave my head all of the protection it needed as I slid along... The best 90 bucks I have spent all year
Initially I was going to buy a cheaper model as in 35 years of cycling I've never really had any need for the protection, but I'm glad that Matt black styling convinced me to pay the extra for a helmet which really did it's job...
As well as the protection, I found this helmet nice and cool and very comfortable to wear on a 16 mile daily commute (for the 6 months until I broke it...)
