this board is a great board to start your longboard life off with.The board is made great for downhill.After you wear down the wheels the board slide great.
the trucks came perfectly adjusted for carving and great down hill aththe same time i just have to sayGOOD JOB MBS
my son loves this longboard got it for his birthday and he has been so happy with it all his friends love it and the price on this was will in my range.
my name is ian and i have been asking for this board and when i got it i was soooooooooo happy it was 8 at night but i still took it out to go ride it for the first time and it rides like a dream. I have been longboarding for about 6 months on a sector nine and its kinda old and water logged but its still one of my best boards.
i chose a 5 star rating because my board got here fast and undamaged. it even got here a day before it was originally projected to be here.the board is easy to get used to.i dunno bruh, i just love to skate.
Which makes it look even better! Its just perfect in every way!! !
We got this for our 14 year old son who had taken a liking to boarding. He loves it. We feel that it is safe, he had a krown pintail longboard earlier, (he didn't like it at all) but it got ran over by a car. We 100% reccomend this longboard, our son rides it without any protection on, and hasn't fallen. Great beginner's board.
