I get a lot of emails, Facebook messages, YouTube comments, as well as kids and parents in person asking me about parts compatibility. Nearly every question revolves around the compatibility of forks, bars, headsets, and clamps/compression systems. This is by far the most difficult part of building a scooter for people who aren't already deep into the sport. Because freestyle scootering is still a very new sport, a lack of industry standards and definitive best practices has led to a wide range of parts and technology implementations. While innovation and variety are great for the progression of scooter parts, it has made the situation difficult for parents and kids who are trying to learn about building scooters.
