Ok gentlemen put on your bike mechanic thinking caps to answer this question for me.
As most will know, I have a 48t chainring on the Wasp and an 8 spd SA hub, but I would like another ring as well , say a 42t or 44t for climbing mountains and keeping the 48t for fast road riding. Now I could manually change it over for the ascents then change back for the descents, but I was wondering if I could try a front derailiuer, and would I need a chain tensioner or rear derailieur to keep things running smoothly?
I checked the height of the 48t ring and there seems to be room on the frame to make it work, does anyone know of a clamp-on deR..... that will fit R-20 tubing?
I humbly wait for your knowledgeable replies in hopeful anticipation
PS: Jur mentioned that he has 2 chainrings on SWMBO's Yeah bike, I wonder if he has found a solution for that?
