i'll admit to the fact that i find it hard to watch vids of helmetless riders, bmx trials or otherwise.
it just seems silly to me to put yourself at extra risk of injury when doing what are already dangerous activities, i never used to wear a lid until i looped out and twatted my head on a curb, the 2 day headache and time off the bike convinced me to get one!
i wouldn't ride without one now
