I have a 1983 Specialized Expedition bike. Currently I am running the original gears which are the front 26/44/48 and the rear of 6 speed 14-28. I know the front chain wheels is not touring savy but as I have been told by a few people that is how they built the bikes back in the day. And for the rear, I would like to have a better range.
Here is my question: Is it possible to put a larger freewheel range on the back with my frame or am I limited? I do not know much about compatibility with all the different kinds of variables there are out there so I am shooting in the dark here.
