The debate has raged for decades about which brand is superior in the bicycle component group manufacturing business. Shimano and Campagnolo make component groups that provide the same basic functionality to a bicycle – transmission, steering, and braking systems. However, each company has several different priced offerings available. In short order, the whole component selection process gets complicated leaving the consumer wondering ‘Why Campagnolo’, or, ‘what exactly am I paying for when I buy Dura Ace instead of Ultegra’? It must be remembered, however, that they are simply bike parts and if consumers stick to these two companies, they will rarely be disappointed.
