im interested to see how many people do
i got into a argument with a bloke on a carrera road bike the other day, there he was in all his lycra, high vis jacket, helmet, sunglasses etc and he comes to the side of me and tells me to get a proper bike, start wearing a helmet and said hed push me off next time he saw me to teach me a lesson, argued a bit and left him in the dust.
i never really wear a helmet, i ride on road, through the local park, over golf courses, canal towpath and only time ill wear one is on hard trails.
