I have a 81 Schwinn LeTour with a 52-39 Sugino Crankset in the front with a 5 Bolt 110 BCD. In the back, I have a 5 speed freewheel.
I'd like to install a compact double on the front, as I am 220lb novice rider and live in a hilly area.
Of course, I'd like to do it at as low of a cost as possible, ie with replacing as few of parts as possible, but am open more complicated approaches.
Some of my questions
- can I find new chainrings to attach to my existing cranks, a lot of the rings I see seem to be for 8/9 speed or higher, which I assume would require a new rear end, new chain etc
- will I need a new front derailer, or will I just able to adjust it?
Any advice welcome
