Re: "San Diego Speed 32" Mountain skateboard long board"
Deck looks a little thin. May not hold up long off-road.
Definitely inexepensive. You know what they say -- you get what you pay for.
If you have $75 to burn go for it. But, I picked up an older model MBS Jeep renegade for $79 on ebay. An old Rennegade in good condition will probably hold up a lot longer.
However, both of these boards use skateboard truck systems. Real performance costs more in the form of "channel trucks."
