Now, if one has a cassette hub all you have to is remove all the rear except 1 and load the hub up with spacers in place of the cogs.
Yeah, that one is easy! And it would have been easier on my Simplon except that I was shy to cold-set from 120 to 130 — 5mm per side. Hence we cut the axle and removed a spacer — and re-dished in the less desirable direction.
Some members may not blink an eye over this. I remain shy to bend metal tubing as much as 5 mm per stay — especially if it is older with "memory". Maybe not an issue. Cold-setting back back 3mm a side seems not so disturbing.
I realize this may derail the thread and start one of the old saws — but if you have done it, I'll accept it as workable and OK.
