Additional Info
I wanted to know what it was like to BMX the bikepark. On a well prepped flow trail or in the queue to the uplift it's awesome. it's suprisingly stable for what it is. Otherwise it's awful. On brake bumps you struggle to hold the bars due to bad vibes. Still really happy I built it!
