clearer Duncan Praxis picture

a clearer picture of the Duncan Praxis.

and how the axle system look like.
i see recess response, different bearing size. and i think i think the external axle is part of one half(which means if u don't include the new axle system, u'll only get yoyo half -> bearing -> yoyohalf, no nut and bolt.) or it could be, the external axle does not require nuts, its like a large axle that most metal yoyo are using but with a hole for the internal axle to go through... and then the internal axle system that holds the side spinning caps will go through the external one.

and a couple Duncan 80th anniversary caps picture.
