Just received my ("NOS with slight storage marks") Sram 9.0 rear Der and twist grip changers. In very good condition and worth the money I paid for them but they have been used on a bike, not NOS. Changers have cable rub and Der has chain wear on jockeys and slide marks on the cage plate. Very well cleaned buy trail dirt in those little hard to get places. No big deal in the grand scheme of things and I would have bought them even if they had been described as lightly used.
Seller has explained that these parts were posted remotely and that he was assured that they were NOS and has offered a full refund. Honest mistake
Keeping them as they are in great condition and worth the money
I will have no problem doing business with him again, excellent communicator and a good guy
