Back in 04 or so. Ricky or someone on Razor pitched that they are MADE for freestyle...so me and a friend bought one each. Yea, they broke. Fuck those things.
Headtube does not work on any other decks, just a heads up... Can't bolt it, the carbon fiber flexes, and if you flex it too much, it will shatter, obviously. I tried it myself, but when it seemed way too flimsy, I took it right off.
