I've been needing some lower gears for some lightly loaded touring in mountains. So I drove to Boston and Harris Cyclery for a smaller chainring for my triple and two cogsets for a custom built rear gearing. What a pleasant experience it was. Even though the store was busy, the staff took time to talk and confirm that what I wished to do was feasible and they did indeed have the parts on hand.
Checking out I commented on the excellent experience and offered the suggestion that a slight improvement may be to place a sofa along a wall somewhere with a few magazines and in winter, a pot bellied stove with a coffee pot atop. They promised to look into it.
