As I’ve seen conflicting suggestions for fore-aft weight distribution, I am hoping to hear some of the theoretical/practical reasons for different choices. For example, for long stretches of low gradient inclines/declines does it matter much? How about steeper grades? Lots of switchbacks? Singletrack? Etc. For reference, I will be loading a Surly Ogre for road and some off-road touring. Thanks in advance for any information/advice.
