There have been three versions of the SON hub for most bicycles. The first was for rim brakes only, designed in the early 1990s. The spoke flanges were polished aluminum, and they were connected by a black painted steel center section, similar to the construction of the early Phil Wood hubs. That version was made up until about 2003 or so. The next (2nd) version was smaller and lighter and was all aluminum. It was available polished and black anodized. It was also available for ISO disc. This version could have the dynamo core and bearings removed by unscrewing the core with a special tool. Because it can unscrew, the connectors must only be positioned on the right side, lest vibration cause the core to unscrew. This is the only version that must only have the connectors on the right side. The third version, the current version, can have the connectors on either side, unless it's a disc version, in which case the hub's orientation is dictated by the location of the disc brake caliper.
Leah's wheel can be mounted in either orientation.
