SHIMANO road bike components respond, backed by a long history of innovative research -- from aerodynamics to ergonomics. This results in smooth, precise, shift changes, a drivetrain system with loss-free propulsion, and a braking system with high reliability.
For those who never compromise
We take years to give you seconds. The pinnacle of Shimano road technology and innovation, the new 12-speed R9200 DURA-ACE is our fastest, most inspired drivetrains ever. Speed was the driving force behind the new generation of road groups, and every decision our designers made was to make you faster. Shimano engineers worked to refine each component and every function to provide the best onbike experience, whether you’re sprinting to the finish on the Champs-Élysées or crushing your local climb.
With great speed comes great responsibility. That’s why we took a holistic approach that was 100% performance-focused in our quest to make the new ULTEGRA group even faster. Whether competing in local club races, trying to beat your personal best or riding for the pure enjoyment and camaraderie, our new 12-speed road group offers unparalleled control and comfort – all day and every day. This is the Science of Speed. And it’s what sets SHIMANO apart.
The new SHIMANO 105 brings Di2 shifting to a new set of riders who have only experienced mechanical shifting – and is set to transform your road cycling experience! With functions and technologies inherited from DURA-ACE and ULTEGRA, SHIMANO 105 Di2 is the culmination of years of research and development. With a shared Di2 platform, sophisticated ergonomics, 105-optimised gear combinations and an exceptional brake system, SHIMANO 105 Di2 marks a new era of affordable performance.
