Really nice Geometry on this one, could not be happier. I've also ridden a Federal Lacey frame, Ty Morrow frame and Sunday Funday frame. The Lacey and Morrow felt really selective to street riding only. This frame feels at home everywhere! holds flow easily, ton's of pop. I have a 21 feels more like 20.8/20.9 because the back end is super short, not complaining at all just means spinning is easier!
Back end is really short, once you slide the back end out it becomes extremely sensitive so if you aren't careful you will loop out (I'm talking about steezy speed check slides) etc. This was the only downside to the frame but I changed from a 50mm stem to a 52 and its not as much an issue now.
I mean you could probably complain about the short back end thing but just slap on a 52mm stem and you're laughing! Best frame ever! Get one, you will not regret it. My Settup is 30mm forks 21inch frame and 52mm stem 9inch bars. Ride Everything.
