The Dura Ace 9000 crankset from Shimano was designed with the highest levels of competition in mind. Improving on the Dura Ace 7900 crankset, Shimano redesigned the spider in order to make the crankset lighter and stiffer, ironically by removing one of the spider arms. This 4 arm construction allows the crankset to be lighter, without compromising rigidity. The Dura Ace 9000 crankset also uses a chain guide design that reduces chain drops. Thanks to its exceptional build quality and incredible engineering, it’s no wonder that the Dura Ace 9000 crankset is the choice of many in the pro peloton.
