Thank you for viewing. This is a set of front and rear V-brakes and a front carrier. The weight of the front carrier is not specified, so I am unsure, but it is a front carrier that can be attached to most V-brake type bicycles. Carrier width: Approximately 17.5cm, height: Approximately 25cm V-brakes: No problem with operation. There are scratches, rust, and dirt. Please understand that this is a used item. I may be slow to respond on my days off. #Crossbike #Roadbike #Mountainbike #Vbrake #Brakes #Carrier #Frontcarrier #Luggagecarrier
