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.

Fast delivery thanks.
Nice color to blend with my black colored road bike.
Excellent as always. My trusted bike shop for equipment and mechanics services. Look for Mr Ho, he generously shared the correct way to install the new chain and make fine tunings so that the gear changing will be smooth.
Had my earlier pair exchanged due to size issue. They recommended me this pair and am very happy with it. The exchange was very smooth and no issues at all. Happy to have bought from them.
It’s nice to have a single, fuss-free lube that I can use across my commuter, road, and gravel bikes. Thanks to this large refill bottle I’ll happily continue with RNR Gold for a while longer.
Item was nicely packed and included some grease with it. Easy installation as well. Appreciate the great service and helpful advice too
Great range of bicycle products suited for every need. Friendly and very proactive staff
Easy to install and more rigid.
