Schwinn Sierra. Aluminum frame, 21 speed. Less than 100 miles of use. It is in nearly perfect condition; the tires still show new tread. This is not a mountain bike; it is considered a "comfort" bike for street or bike trail riding; regular handlebars, spring seat that is very comfortable; sturdy. Asking $250.
