I plan on upgrading my 00-03 Boardwalk D6. Right now it's a 6 speed. I was wondering which way to go. I have a 7x3 Sachs dual drive from an old recumbent, nice but heavy. I was also thinking of adding a triple with a FD, but do't know what size FD to get . Has anyone trying or did this kind of upgrade before.
