My lbs guy shifts to the small ring and smallest cog - he says it saves wear on the springs in the derailleurs. Not sure if it's true, but it's a suggestion. How's security in the basement?? Mine all live in conditioned space, so I'm not the best to ask (2 in the extra bedroom, 1 + a tandem in the dining room and 4 in the living room between 2 people).
