rhino, many folks here are super knowledgeable on tandem stuff. i mean, RIDICULOUSLY good knowledge. since my wife and i are total beginner tandem riders (although i've been riding or occasionally racing on road for 25+ years), they helped me with so many questions i wouldn't have known to ask when i had my first custom tandem done--which wrapped up just recently.
luckily, my builder has built many, many tandems, and from what i gleaned here i could have intelligent conversations with him, which was really helpful.
