About this product
The SRAM GX Eagle 12-Speed Rear Derailleur (Type 3 RD-GX-1-B2) is a long cage mountain bike component, weighing 294 grams. Designed for SRAM 12-speed drivetrains, it mounts via a hanger and is specifically engineered for mountain bike applications. Manufactured in Taiwan, this derailleur is sold as a single unit, providing precise shifting for demanding off-road conditions.
Our take
As a dedicated mountain biker, a reliable rear derailleur is non-negotiable, and this SRAM GX Eagle unit certainly fits the bill for 12-speed systems. Its 294-gram weight is competitive for a long cage design, and the Type 3 designation usually implies improved chain retention. Designed specifically for mountain bikes, it should handle rough terrain well. Just remember that it's built for SRAM components, so compatibility with other brands isn't guaranteed. For its price, it offers a solid performance upgrade or replacement for a SRAM 12-speed setup.
