Steve,
Thanks for the info. I guess if I go back to a triple, the granny
gear would be nice. A 10 speed 12-30 with 24-34-44 seems to have a
decent range.

I'll keep playing with this and with whoever does the build to make
sure it can all work together.
Indeed, triples can be very nice. But, like everything else, there's a
good side and a bad side. Bad sides include triples not working nicely
with integrated brake/shift levers, shifting difficulties (e.g.,
dropping chains, missing the middle ring, etc.), greater q factor, and
for some people excess complexity. Also, if the chain rings aren't well
chosen you can throw away the advantages in range and end up with more
complication and nothing to show for it.
As for the triple you point to: that ratios on that setup are very much
to my liking, the range fitting my needs very well. But does that
cassette actually exist in the real world? I'm not aware of a 12-30 10
speed cassette.
