The updated cage position means it rests directly under your frame’s chainstay, reducing drag and protecting it in the event of an unfortunate racing incident.The Shadow design also offers faster wheel changes thanks to the fact that it moves the derailleur out of the way of the dropouts. It also offers faster and more precise shifting than ever before. Shimano's 9150 groupset brings its Syncro-Shift technology to the road too.

The front shift is then automatically operated to position the gears in the most efficient gear and best chain line. This means you'll never have to worry about front shifting and correction shifts again.Features: Speed: 11-Speed Compatibility: Shimano Di2 road shifters (Dura-Ace and Ultegra with E-tube connection) Maximum Low Gear Sprocket: 30T (Minimum 25T) Minimum High Gear Sprocket: 11T (Maximum: 14T) Maximum Front Difference: 16T Total Capacity: 33T Mount Type: Standard hanger mount Clutch Type: No Ergonomic shifting operation without stress Shimano synchronised shift Low profile rear derailleur design Shimano Shadow cage design Race endurance for less damage in a crash Maintains compact and smooth appearance Manufacturer's Part Number: RD-R9150 Weight: 204gA 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
