Hi there, I'm looking at some used Tallboys. They are all LT, those seem to be the precursor to the Hightower, is that right? Does the long travel make them less of an all day bike for climbing as opposed to a new Tallboy? What would the spec on them be, would they be boost spacing so I could think about going to 12 speed? I'm 6' tall so would a side L be about right?
