We have lots of hills on all of our trails (and not rolly hills), so I'm going to start fairly easy with a 32 front and 20 back. They usually run a 2:1 ratio for gearing and so if I'm feeling I can handle the hills without killing my knees I might switch to a 16 in the back.

The difficulty with the 32, 20 will be smooth, slow pedalling on the flats since that is easy gearing, but I'm sure I can benefit from this as well.

My hubby is waiting on some horizontal dropouts and when those arrive, I'll be ready for single speeding.

There is so much info. out there it's hard to keep everything straight.
