This one puzzles me. ebay item 110209598317 http://ebay.com/<blah>

why would one need a high low Track hub? I always thought the high low hub was designed to compensate for the unequal spoke tensions created by dishing on 5 and 6 speed freewheels. I also was under the impression that a Track hub will have less required dish due to the more symetrical design of the hub.

So, unless I'm totally wrong (wouldn't be the first time) whats the rational behind this hub?
