Hi guys, thanks for the replies. I am learning out of the gate here. I did not realize the various different stack heights. So is stack height for a particular head set a function of spacers or of the other components or both? If my frame has a 157 mm steerer tube length and a 125 mm head tube length does the math mean a 32 mm stack height? Thanks for the further education. This is going to be fun.
