Sram Red eTap AXS rear derailleur:This is the Sram Red eTap AXS rear derailleur. Designed for 1x and 2x, the derailleur keeps the chain quiet and safe thanks to Orbit ™ technology. Orbit chain management technology uses a silicone fluid damping system which, unlike a friction clutch, does not add additional friction to the derailleur spring when performing slow / light movement. That means changing and removing the wheel is easy, but chain bounce and slap are reduced. In addition, AXS technology allows you to customize your changes to your liking.BlipBox AXS box:
