Crank Set SHIMANO DURA-ACE FC-R9200, FOR REAR 12-SPEED, HOLLOWTECH 2, 172.5MM, 50-34T W/O CG, W/O B
630,00 €
The Shimano FC-R9200 crankset efficiently converts the power you put into your Dura-Ace 2×12-speed road bike groupset into propulsion. It weighs about 20 grams less than the Ultegra model and meets all your requirements for stiffness and stability thanks to the Hollowtech II design. You also benefit from the precise and fast shifting processes you are used to from Shimano drives. The crank arms are hollow-formed, as is the large chainring, which is partly made of carbon, resulting in significant weight savings. Apart from the axle, all essential parts were made of lightweight metal. FC-R9200 has an asymmetrical 4-arm bolt circle diameter of 110 mm. It produces a chainline of 44.5 mm and has a Q-factor of 148 mm. The 40-54 tooth gradation option is specifically designed for competition use.

Technology:
Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
