I have a triple crank on the front and I am thinking of getting a better
quality rode bike. I live in the flatlands of Illinois and normally I
just don't see a need for the real easy gears on the granny gear. Seems
to me a standard double crank with 9 or 10 gears is basically the same
and less to deal with, is this me or what do the more experienced riders
think? I normally just rode bike for miles at a time at whatever pace I
can maintain to keep the fitness for running without the pounding.

12,13,14,15,16,28,20,23  plus one ring of choice a 46 perhaps.  No
front mech.

You'll still need a chainguide or a derailer to serve that purpose. Just
ask David Millar:

And unless you're weight-phobic, that's a reasonable excuse to plop a
second ring on, even if only to serve as a chain-keeper.


Not a problem when using a single pivot mech. Modern rear mechs may
havve their top springs removed or the top pivot locked in some other
way and they will then perform as good as a single pivot on a gear
train. Time triallists used a compact 6 with a Nouvo or Super
Record. Usually on a 54 ring. The NR would also be used on cross
bikes which may have 2,3,4,or 5 sprockets depending on rider
preference. Compact freewheels were not adopted for cross as quickly
as for road, we were still in the day of friction levers, not ideal
when combatting a rough or slippery course, hence the low count
freewheels.
