Looking to buy my first Road Bike this summer, and don't have much knowledge of what I should be looking out for. A friend recommended that I get Shimano 105 gear front/back setup, aluminium frame/carbon fork and enough clearence for mudguards and panniers. I currently have a Ridgeback Supernova with Deore frn/bck gear set up, which seem quick and smooth, does anyone know whick gears set up are best for Road Bikes?.
