Thank you for viewing. This is a rear carrier for a sports bicycle. Made of aluminum, with mounting screws, manufacturer unknown. This type is fixed with a seat clamp. Some paint processing is present. There are scratches, dirt, and rust on the screws, but it is still usable. Width: 45.5cm Height: 36cm Depth: 13.5cm There may be some errors as it is amateur measurement. Please understand that this is a used item. I may be slow to respond on my days off. #carrier #luggage rack #cross bike #road bike #mountain bike #rear carrier #seat clamp #aluminum material #custom #custom parts #repair parts #repair
