Sram has now launched the GX Eagle AXS 12-speed wireless electronic upgrade gearbox for MTB - AXS. The group brews on the technology from their thoroughly tested and super well-functioning Etap technology. The system is the fastest gear change Sram has made so far, just as the group is easier to set up easier to maintain than wired systems, and of course it just gives the bike a much cleaner look. Easy to mount on a bike as no cables need to be pulled and the setting is made on the Srams app. The group is made up of: Rear derailleur and Trigger. Can be set via Srams app. The group comes with charger, guide and setting tool.
