I am planning to switch my freehub (cassette body) from shimano to campy. American Classic sells a new freebody for my hub and provides instructions to make the switch.
The instructions seem very straightforward execpt for redishing the wheel. I am mechanically inclined and been working on bikes for a while now but not sure what "redishing the wheel" is? That being said, how would I go about doing it?
Also, as a side note I am not sure I understand why it needs to be done? Isn't redishing centering the rim over the axle? if so, shouldn't the axle already be centered on the rim? Why does swapping a freehub require redishing if the difference between a shimano and campy cassettes are splining and index spacing?
Lots of question and no answers...thanks in advance for sheding some light here.
