With the introduction of DURA-ACE R9100, Shimano has reestablished the new benchmark for road performance by improving each component and incorporating its newest technologies. DURA-ACE R9100 delivers unparalleled performance, highly-refined ergonomics and immense customization to maximize every rider’s potential.

Engineered for the next generation of race bike, DURA-ACE R9100 offers top-tier performance across numerous configurations. Available with either Di2 electronic or mechanical shifting, for the first time, riders now have the option of premium DURA-ACE hydraulic disc brake performance. New Shimano technologies further integrate the DURA-ACE as a system, including a new power meter, while riders further integrate with their bike through new E-Tube wireless connectivity.
