Question: does the board have any concave to it?
Document: I only had the board for maybe a week or less  and the deck snapped in  half on me when I was riding it
Company screwed up my order and I had to call to even get my board...finally after close to 3 weeks I got this deck and it was twisted and won't ride straight. ..waste of time and money
The one issue with this board (at least the one I got) was that the wheel cutouts were not even with the drilled wheelbase, but honestly, with lifts and shock pads in there, you don't need it.This is a heavy, quality piece of maple that I have gotten multiple compliments on, even from people who don't skate. The wood is solid, and holds me easily at 208+ pounds with no warping.
Very stable, very strong, great to rise the nose on, assuming it is the same product I purchased here (I notice other vendors sell this now).
My son and I designed and assembled his &#34;custom&#34; longboard. He has all the kids wanting to build their own now.
Answer: no
