SHIMANO Dura Ace crank 2-speed FC-R9200
The Dura-Ace FC-R9200 crank not only converts your pedaling power into propulsion, with its high rigidity it also ensures extremely fast and precise switching behavior. The high switching precision is supported by the optimized chainring design. In order to keep the weight low, the Japanese continue to rely on the proven Hollowtech II construction of the crank arms. A large selection of crank arm lengths and chainring options ensures the availability of the right crank for every type of rider and every terrain.
