as for shifting, you really do not want to be in a big (front) small (rear) combo it, will most likely cause the chain to rub on the front derailleur.
Correct me if I'm getting confused, but isn't it the other way? You don't use the smallest front cog with the smallest back cog, or the largest front cog with the largest back cog?
Because the biggest front with the smallest rear is your fastest gear, and the smallest front with the largest back is your easiest gear...
