So I have this old Peugeot UO-8 that I was thinking about upgrading for a long touring trip. First thing is obviously a new drivetrain, because 10 speeds just is not going to do it for me haha. I know that a triple crank will fit on the front, Probably a Specialties TA Carmina crank or the Specialties TA Pro 5 Vis (the Cyclotouriste) Crank.
But I was wondering if a 9 speed gear cluster will fit on the back, because the gap between the chain stays on the Peugeot is only about 5 inches - 130 mm? (not sure about exact measurements in mm) where as the gap on my newer 2009 touring bike is about 6 inches - 150mm? If not a 9 speed... would a 7 speed fit?
Don't want to go spending money on something that isn't going to work heh. Any info is greatly appreciated. Thanks!
