I considered the Bell when I was searching for a bright yellow helmet. But I have a SUPER small head, and despite all adjustable straps, helmets are simply too large for me when they only come in "one size fits all". Been there.
Either I need a woman's helmet, or else a smaller adult helmet. I wound up getting the Limar yellow helmet (now discontinued) because they offered it in TWO adult unisex sizes: S/M & M/L. I got the S/M and it fits me fine, but just barely- I have to dial in all the smallest adjustment settings & straps down to the smallest possible. It has the same dialable wheel band that Knot describes. It's great.
I just "know" the one size Bell would be too big for me, adjusted or not.

Wondering when the manufacturers will get a clue again that we want some traffic visable helmets. They are so hard to find these days!
