Hey Interested-What you have demonstrated is that by your own admission internal gears are more popular with commuters in your area.

Even though they are in the majority you feel they made the wrong choice and that you are the correct one and they are incapable of making a sound decision.

Don't know if you noticed but you are in the Commuting forum. Might try the road forum for a more favorable veiw of derailleurs.

Cheers.
