Suntour aR Long Cage (GT) Rear Derailleur


This Suntour aR Long Cage (GT) Rear Derailleur is in great condition both cosmetically and mechanically. All parts are original and there is only a few cosmetic blemishes. The "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 completing break down these components to inspect and clean before reassembling.

This derailleur would be great on a vintage mountain bike or touring bike. It does have a small amount of pitting on the inner cage arm, but otherwise is in excellent condition

All of our vintage parts have been disassembled, cleaned, inspected, polished and reassembled with lubricants. They are ready to install.
