Purchased one year ago and used a few times. There are a few places where the surface paint has peeled off due to installation, so please check the photos. I believe all the accessories are included. There is a rattling sound from something inside, but I confirmed with the manufacturer, and they said that it can sometimes get mixed in during the manufacturing process, and it didn't bother me during use. Price negotiations will be handled based on your desired price, not in the comment section. Below is the product description from the website. I cannot answer questions about compatibility, etc. 【Product Features】 A new aluminum rear carrier that can be installed in 15 seconds and removed in 5 seconds. Unlike conventional bolt-on fixing, you can work without tools by pre-installing a dedicated mount on the rear end side's eyelets. The top part is quickly and easily secured by fastening a belt to the seat tube. Compatible with QL1/2.1/3.1 systems. 【Specifications】 Compatible with 26"/28" Black 580g/15kg/QL1/QL2.1/3.1/TOP LOCK compatible Aluminum Weight capacity: 15Kg
