SRAM RED AXS Rear Derailleur 2-Speed, Battery Not

Their retail price online is 799 (currency) for a new one. Note: The rear derailleur was used by me, a 120 lb (~54 kg) rider who takes immaculate care of my bikes. HOWEVER, it had an aftermarket pulley (Ceramic Speed) installed, so the original manufacturer's pulley that has been put back on now has not been used. The rear derailleur works great - no issues. I'm only selling because I'm moving the bike to a different form factor and frame to reduce the cost of the new frame set by selling off the parts separately. I'm building up a new road bike with newer red components, so I don't need this one anymore. As you can see, it's in like-new condition with no scratches, etc. Postage available
