I used the red matter's and for the vert ramp they slip and slide i kinda crashed like that KC kid but with out the crowd of people and face smashing part. On concrete they stick really good but are super fast in teh 110mm version. Airing 4-5 feet is easy just rolling in. Plus the hub is a solid...
the head sets bend, those sting rays were one of the first scooters to come out after the razor. I was riding a stingray scooter with the 125mm wheels and hopped a curb and it bend, then i folded it, and it would never unfold again.
I have A1 bars rigged on my SR fork on my razor A4 so they spin for over 30 seconds at first then progessively get worse till the scooter is more loose than a hooker in vegas.
damn, well it cracked when i tried to jump from the top ledge to the bottom one and the very back tapped the edge, i mean so far back in dented the wheel.
