Outer Chainring Shimano Dura Ace FC-R9200/FC-R9200-P 12s Black

DURA-ACE R9200: Built without compromise 

Shimano’s study in the science of speed has taken developments to a completely new level. The freshly redesigned DURA-ACE groupset provides an abundance of evidence that Shimano will leave no stone unturned in the pursuit of next-level speed.

Drivetrain System: Quick & Shockless Shifting 

The new R9200 series is also the debut of Shimano’s new 12-speed road technologies. The new 12-speed cassette retains the 11T top gear but has been optimised in the sweet spot gears. The gearing between 6th, 7th, and 8th sprockets has been optimised for the Shimano hallmark of smooth and consistent steps. The ramped profile of the cassette allows for smoother gear shifts, even under heavy load, no matter whether you're moving up or down the cassette. The updated front derailleur promises a 33% smaller frontal area, brings a weight drop of 96g, and offers capacity for big rings ranging from 50T to 55T. Paired with the cassette options including 11-30T & 11-34T the R9200 groupset offers higher transmission efficiency than smaller chainring options and helps pro riders chase ever-increasing speeds.
