Have been riding for 4 months now and really enjoying it. I normally put my hand up or a quick "good morning" etc when passing other riders along our country lanes. I have noticed people riding touring or mountain bikes will nearly always acknowledge with Hello or similar, the same cannot be said for race / road bikers, the times I have been blanked is amazing, its almost as if I have intruded on their ride. Is it better I don't acknowledge other folk ?
