Rear hub – Change your cog without the need for special tools. With the knuckle interface there is no lockring. Therefore, no special tools and no need to worry about torque loads initially applied to the cog when mounting. The shear stress and torque loads are transmitted through the hub by the three Knuckles. The three bolts do nothing but hold the cog flush to the Eye (center) of the hub.  Dead center!

Because of the "no need for special tools" design, repairs can be done virtually anywhere.  It uses a TorX wrench, size 25, for the mounting bolts. (the same size threading on a typical water-bottle braze-on). The TorX size is currently used in the industry for disc brake rotors and is now available on most bike specific multi-tools.

Oh, and, btw, you can change the spacers from 120mm to 135mm, flip the cog around and have a 45mm chianline or a 52mm chianline.  Whatever your pleasure
