I know some of you are using or have recommended a double chain ring of 53/39. With an 8 speed 11-32 freewheel, that will give you a range of 24.4" - 96.4".
Since i'll be sometimes using the folder to do touring with a 30 to 50 lb load, i'll need a wider range (need to save my knees and spin). Pardon my ignorance, but could I easily use a 56/32, which would give a range of 20" - 101.8". Would it effect the folding? Would I need a better rear derailleur? This would almost replicate the Dahon TR range of 19" - 99".
