Just add another chainring?
I was looking at an advertisement for my 1986 Bridgestone 400 the other day and noticed that it showed a third, inner chainring as an optional item to have put on the bike.
If I had an extra triple crankset sitting around (which I do), would putting the triple on my Bridgestone be as simple as bolting it on and then adjusting the hi/low on my front derailleur (Suntour AGX)? Or am I really looking at having to find another front derailleur with enough travel to accomidate a triple chainring?
