Shimano Dura-Ace FC-R9200 12-Speed Crank Arm Assembly - 165mm
The benchmark redrawn. Hollow Dura-Ace arms engineered for 12-speed power.
The FC-R9200 crank arm assembly is the foundation of Shimano's flagship 12-speed road drivetrain. Hollow aluminium construction delivers class-leading stiffness-to-weight without the complexity of carbon, while the Hollowtech II interface provides the proven 24mm spindle connection that's kept Shimano cranksets at the front of the peloton for decades. Available in seven arm lengths from 160mm to 177.5mm — the most comprehensive size range in the Shimano road lineup. Chainrings sold separately.
Chainrings not included. These arms are sold without chainrings. Pair them with the R9200 ring combination that suits your riding: 50/34T compact, 52/36T semi-compact, or 54/40T standard — all available separately on PDL.Bike.
What makes this worth it
Hollow Alloy Arms
Weight-optimised hollow construction delivers Dura-Ace stiffness without carbon's fragility. Built to power through years of hard riding.
Seven Arm Lengths
The widest range in the Shimano road lineup. From 160mm to 177.5mm — every rider gets the fit that suits their biomechanics.
110mm Asymmetric BCD
One spider works across all three R9200 ring configurations: 50/34T compact, 52/36T semi-compact, or 54/40T standard.
Hollowtech II Interface
Shimano's proven two-piece 24mm spindle system. Stiff, light, easy to service, and compatible with a wide range of bottom brackets.
Di2 & Mechanical
Works identically with both R9200 Di2 electronic and R9200 mechanical groupset variants. One crank, two drivetrain options.
Choose Your Rings
Sold as arms only. Add the R9200 chainring combination you need now — or swap rings later as your riding changes, without replacing the whole crank.
