Shimano Dura-ace Groupset 12-speed Fc-r9200 Di2 – 172.5mm 52-36t

Dura Ace R9200 – Never Compromise

The Science of Speed. Speed was the driving force behind the development of this new generation 12-speed road bike groupset. Several years of research produced the innovations that make the Shimano Dura Ace R9200 even faster. Every component has been revised, refined and optimized to give you that decisive seconds advantage – whether as a breakaway from the peloton or in the final sprint on the Champs-Élysées.

The electronic Di2 components use wireless technology where it counts to make shifting even faster and more reliable. The Hyperglide+ system, already familiar from the MTB segment, is also aimed at smooth shifting and is designed to bring out the maximum performance and full potential of every racer.

Shimano Dura Ace FC-R9200 crankset

The Shimano Dura Ace FC-R9200 crank performs two crucial tasks: It converts pedal power into propulsion and ensures extremely fast and precise shifting. Not only the lightweight crankarms manufactured using Hollowtech II technology contribute to this, but also the uniquely designed chainrings, which have a Hollowglide hollow construction and ensure fast and smooth shifting. The result is responsive acceleration from any speed, which ensures that the 2×12-speed crankset is an absolute top performer.

Hollowtech II

The leitmotif of Shimano’s Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency.

The aim was to produce a crank that minimizes the effort required for the drive unit and enables more efficient power transmission. An exclusive forging process enables the production of extremely light crankarms that still guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve to achieve an optimum ratio between stiffness and low weight.
