Tom: Good on ya for sticking with the Jubilees... NICE TOUCH!!! I believe
the original crank had a 42/52 combo. I would think you'd simply need to
mount the front derailleur slightly lower on the seat tube (and position it
to accommodate the wider distance/range created by the 46/32 combo).
On some older front derailleurs the inner side of the cage does not
come down as far as they do now days. If it doesn't reach low enough
that might impact how well it upshifts across the larger (14 vs 10
tooth) change in ring size. Going the other way, I found that a new fd
didn't work the way I
I think BB has it right - the vertical right cage clearance over the bare
large ring is clear a penny all the way around, but usually just the front
end of the derailleur will be the close end, since the cage arc will have a
larger radius than the chainring.
