Bamboo- Nice Board!
I haven't owned this for too long, so I can't speak to the long term durability of the set up at the moment, but I will come back and update when I've had it for longer.
That being said, it's pretty nice. The graphics are clean and minimalist. The bamboo is gorgeous and Gold Coast makes sure it shines. The clear grip tape on the top lets the natural wood show through and still has enough grit to make you feel secure.
In regards to flex, this board is pretty stiff in comparison to most other longboards I've checked out (Sector 9, Arbor, Never Summer). It does have some flex to it, and seems to be breaking in nicely the more I ride it. The set up is also heavier than the more flexible set ups from other companies. I'm not sure what the flex difference is between the bamboo model and the maple ones.
The trucks are Century 7" Reverse Pivot Trucks, and I haven't changed them out. I'm not sure why other people are having issues with them, or if something has changed with the trucks recently, but mine turn super smoothly. Despite the length/size of the board, the trucks make it extremely maneuverable. Even relatively tight turns are no problem, and I haven't had to adjust them at all.
The wheels and bearings seem to ride pretty smoothly as well. On flat concrete, a couple of pushes will leave you rolling for quite a while. I got white wheels with mine, and they look awesome with the board, but obviously get dirty super quick.
Overall it's a fun board to ride. It turns easily and rolls smoothly. It's more stable feeling than the flex decks, but definitely heavier, so if you're looking for something to flip around a lot, this may not be the right choice. You can do manuals and nose manuals on it, so that's fun. I'm sure there's a lot you can do with it, but I haven't had it long enough to test it's limits just yet. I'm mostly using it for cruising around and small hills.
