John, what exactly was the main benefit of through-the-chainstay cable routing? At the time I thought it was extremely cool and protected the shifter cable, but did it speed frame building any more than simply slapping a delrin bottom-bracket-routing guide on the underside of the bottom bracket, and having a cablestop cast into the dropout?

Was there any real weight savings vs. the delrin cable routing?

Were there any other advantages?
