Steel bicycle carrier With casters, silver painted Used twice for transporting the bike. The drawback is that the folded width becomes slightly wider when this carrier is attached. There are some minor scratches, but overall, it looks clean. Weight: 955 g * Excluding mounting bolts (Mounting bolts are included) I always thought it was aluminum, but a magnet sticks to it, so it's iron. Not compatible with all straight types. It seems to be exclusively for types where the top of the rear suspension mounting part has the shape shown in image 8. You might be able to attach it to other models with some ingenuity, but please do so at your own risk. Please check the dimensions of the screw holes before considering purchasing. * Measured approximately 323 mm (center of hole - center of hole) Please refer to images 6-7
