The builder refused, claiming that the Shimano Super Plate was much more durable. The bike was actually delivered with a SunTour LeTech since he hadn't gotten in a Superplate. I used it for 3 months, and had trouble with it shifting either too far or not far enough at both extremes. Repeated adjustments didn't help. The tandem has barcons, which do indeed make shifting somewhat vague, but you don't really want to take your hands off the handlebars on a tandem :-). Anyway, the builder exchanged the LeTech for a Superplate, which I find to shift much more positively, particularly under load. The gearing is 24/44/48 front, 11-32 rear.
