Correct me if I'm wrong, but, a new 114 that's symetrical won't work. Are the 114 bb's assyemtrical that much to the drive side???
You are correct. You want the 26 mm for proper chainline. Thus for a symmetrical bottom bracket the spindle length should be: 26 + 68 + 26 = 120 mm.
You can use bottom bracket spacers, if you are OCD and want to micro adjust the chainline. Use the spacer on the bottom bracket to move the chainwheels out; use the space on the freewheel to effectively move the chainwheels in.
