Cyclists want their rear derailleur to shift perfectly, whether climbing or in the final sprint. The GX Eagle rear derailleur delivers on all these promises with a redesigned cage architecture that improves chain management. Redesigned to work with the new 10-52 tooth cassettes, it is also retro-compatible with the 10-50 tooth versions. This gives riders a choice, as it should always be the case. Adorned with the new GX Eagle main color, to match all the cassette and chain colors chosen by the rider from the Eagle Colorsystem. Further proof that the GX Eagle rear derailleur is there for one thing: to do its job.
