Really quick release shelves! The load-bearing capacity is 50KG, the new batch is upgraded to the goods, and the seat size adjustment is upgraded to a quick release buckle design, and the upgrade does not increase the price. Dear, without straps!note:1. The seat tube diameter is less than 32mm can be installed, please do not measure the seat tube diameter before shooting!2. Because the shelves are painted with paint, friction and collision are inevitable during the transportation and express delivery. Please forgive me if there is a slight scratch or paint falling off. If you care about the details, please be careful!
