ive been commuting to work for over a year now and through the summer put in some miles (15-25 mile rides) on the country lanes local to me. the bike ive been using is a diamond back mountain back with front suspension and slicker tyres so is heavy and not fully suited. im wanting to give road cycling a lot more attention in the near future but im unsure of what type of bike to buy. i see these road bikes with drop down bars and they all seem small to me and potentially uncomfortable for my size. im 6'2" and a well built 18+ stone. ive looked at the hybrid style bikes with normal bars and slim tyres like road bikes. would this be a good comprimise or should a road bike with large frame be fine? id appreciate any advice on this area as im really unsure at the moment.
