Review on Zol Bicycle Inner Presta Valve by Bryan Covington

So my 12 year old son collects discarded bikes and tears them down using recycled parts from other bikes, new parts (if he can afford it) and paint/elbow grease/and time. He makes a "new" bike to give to a kid who might not be able to buy a new bike. His creations were amazing, his hands were injured, his patience tested, he's always learning, but his heart is in the right place. He had trouble finding a camera this size. He didn't get a chance to test it as he's still working on putting the bike back together. But he wasn't disappointed with the new parts he was able to acquire. He noticed that the end of the valve stem on the pipe was different than what he was used to. Encourage children to grow and be creative.
