small, im pretty sure its a 15, so it feels like a 17, im gunna get a 17 so if feels like a 18.5 (using advice i got from a store and a website) but I cant find out what size the ns is. Don't wanna buy it and end up with the same size frame, ive checked everywhere, their official website, a bunch of stores, gone searching on forums, cant find the freaking size. Some ones got to be able to tell me the size.
