Setup the Lock-in classics today...some interesting finds:
The inner bearing seat is very recessed (or perhaps the seat is super slim, I don't use spacers) - unlike the nano rats where the inside/lock in portion gives more hanger width as is sit more flush against the end of the hanger - on the spits it actually eats up more hanger than you'd think as they hanger goes into the wheel / bearing area quite a bit deeper, even deeper than a regular classic (and deeper than a regular lockin); this also means the hanger sticks out more...
Initially I was going to run 144s but after putting these on, it almost turns them into 139 hangers (usable grind space), so much lost hanger room. Going to have to run 149s instead or a hell of a lot of inner washers (edit: it took four thicker washers hanger-side, both sides, on a 144 to get the nut flush, with the tiniest bit if play).
