At CUBE, we don't compromise on the development of our kids' bikes either. That's why the lightweight Acid 200 Disc frame is made from the same high-quality 6061 aluminum tube sets as our adult models. It is stable and durable, able to withstand even the highest demands and the wildest maneuvers. Additionally, it features disc brakes on both the front and rear wheels, as well as a replaceable derailleur hanger, so that after a fall, you don't have to replace the entire frame. The quality is clearly in the details!
