Review on ROCKBROS Bicycle Cycling Accessories Mountain Sports & Fitness by Mark Ponnusamy

The quality of the bag is normal, but not practical, the designers didn't think much about the design, it is only suitable for a certain type of bike. If your bike has a rear fender or your seat post is down, it will be very difficult to functionally attach the bag to the bike. I have never had such problems with German products. This product isn't cheap, so I would advise adding a few dollars and buying a German or European product (refers to seat backs or bike accessories in general).
