Dura-Ace R9200 Di2 Rim Brake Groupset Bundle

Shimano Dura-Ace R9200 Di2 Rim Brake Groupset Bundle

Shimano’s Dura-Ace R9200 Di2 Rim Brake Groupset is the pinnacle of the brand’s road technology, engineered for speed, smooth operation and sleek aesthetics.

The brains of the system, the R9250 Rear Derailleur houses the wireless hardware that communicates with the shift levers, and it’s hardwired to the front derailleur and battery, acting as the master link. It’s also the charging point, provides ANT+ connection to third party devices, features the button responsible for all Di2 operations and integrates an LED light for shift modes and battery charge levels. The longer cage length means that compatibility with 11-28 through to 11-34 ratio cassettes is fully supported. A carbon cage increases rigidity and lowers weight, while the corrosion-resistant cold-forged aluminium link plates of the derailleur body are strong to donate snappy gear changes. The overall profile is realised via Shimano’s Shadow concept to create a minimal silhouette, and a “fuse” function automatically activates during a crash to protect it from damage. DuPont Zytel pulleys complete the design, guaranteeing durability and damping drivetrain noise.

Hyperglide+ technology in the sprockets and chain mean that the two mesh better, essentially improving shifting under load, across the cassette.
