Extra Extra Extra Large Helmet Required

   I signed up because my attention was drawn in another cycling forum to this thread. My head is also 66cm and long and narrow compared to the average, so I'm interested to know whether you did find a helmet to fit.
I've only ever found one, and that took my local bike shop ten years to track down. It must be 20-25 years old now. I do have a Met Idolo that's a nominal 62cm, and sits rather high at the back, but gets me into events that insist on helmets, even if doesn't fit and isn't comfortable.

I mostly ride without. Whether or not the things actually work, I'm massively ahead on life expectancy from riding a bike in the first place, and that dwarfs all risks, so I'm keen to keep riding (quite apart from the enjoyment).

I tried a 66cm Bontrager Circuit Wavecel today. Smallest 66cm I've ever come across. Significantly smaller than that Met.

	We failed to find a ready made option so now are going through a lengthy process of buying a custom fit from KAV in the USA. I will do a write up for the club mag once the final helmet arrives.
