Rockshox Reverb AXS A1 Dropper Post 30.9, 170mm. No battery, charger or remote included. Works awesome! Signs of use just minuscule scratches from desert riding as pictured, has been used for a few months. Has never felt solid even after bleeding air out the vent valve / pumping to 250 psi. If you don’t care for any of those things, this dropper is for you!
