Shimano 105 R7100 12 Speed Rear Derailleur
The Shimano 105 R7100 12-Speed Rear Derailleur delivers smooth, stable shifting and wide gear range compatibility for your road bike. Featuring Shimano’s Shadow RD technology, this derailleur offers a low-profile design that keeps shifting precise and quiet, even on rough roads and during aggressive riding.
With a maximum low sprocket capacity of 36T, the Shimano 105 R7100 supports a wider gear range, making it ideal for steep climbs and versatile riding conditions. The direct mount compatibility simplifies rear wheel removal and enhances frame design flexibility, especially for modern bikes with large chainstays or thru-axle setups.
The Shimano Shadow RD design minimises derailleur projection to reduce the chance of impacts while maintaining consistent chain tension for smooth and silent operation. It’s engineered for riders seeking reliable performance and easy maintenance on their 12-speed road drivetrain setups.
