RDER - Suntour aR Short Cage Rear Derailleur (2023)

This Suntour aR Short Cage Rear Derailleur is in great condition both cosmetically and mechanically. All parts are original and there is only a few cosmetic blemishes. Spring tension and pulleys are in very good condition. The "Suntour aR" stencilling does not hold up to the strong water-based degreasing detergents and has been removed as a result.

I am a fan of Suntour components. They are very well designed, strong and function smoothly. As a restorationist, I especially enjoy being able to completely break down these components to inspect and clean before reassembling.

This derailleur would be great on a vintage road bike.

All of our vintage parts have been disassembled, cleaned, inspected, polished and reassembled with lubricants. Our prices reflect the value of the derailleur and the cost to disassemble, inspect, clean and reassemble. It is ready to install.
