I have a 14/25 using 8 of 9 on a126mm wheel dished for 130mm dropouts.
I made up the cassette from a 10 speed and a 9 speed cassette.I don't know
why it is so difficult to get that 16/17/18/19 spread on a cassette,
But how did we manage in the old days when we only had five ratios on
and it was a pig to change the freewheel. Now I can change them at a whim.
Bye the way does anyone know what the standard ratios on a five speed
block used to be? Mine was a 14/25 but I can't remember what the inner ones where.
