The GC mega set up is a really good way to try a flat set up if you’re curious to see what all the hype is about. The Complete set up fits most UFS skates and comes with eight GC turbulence 64mm rounded profile wheels and bearings all pre built. The Mega H-block arches around the inners of the centre wheels to help allow grinds that would catch on regular frames with 64’s in the middle. Something to bare in mind, flat set ups generally weigh more that anti rocker set ups due to the depth of the frame and extra material on the H-block before added the addition of the wheels / bearings.
