The seatpost clamp is great, I would recommend getting one if I knew where to find one/what brand/and what size it is since I got it free haha. But yeah it's totally solid, it can tighten down way more than the stock bolts and it doesn't get all rounded off from tightening since it's made of something a lot better than Razor ones haha.
And I'm planning on spray painting the spokes on the Yaks black, because they don't match and they look like ever other kid's in the world.
