My name is Brock Waidmann, I'm 16, and I was born with Spina Bifida. I have 2 younger brothers who both skate.  My first time shredding WCMX was at Venice Beach, CA in 2013.  I really love this sport!  We live across the street from a skatepark and would love to do this everyday!  It's so fun skating with my brothers too!  A WCMX chair would help me get better and save my regular chair from damage.  I found a really great WCMX chair from SeanCo WheelchaIrs that I would love to get.  Any help would be awesome! Thank you!
