k, in my quest for tandem, I've spottd a lovely Dawes Kickback two with custom butted 501 tubes. No sleeper brake, and cantilevers . Any one had any dealings with this make of bike specifically. Seems for me to be slightly above average price for the model, but it does look nice. What is 501 like in a tandem frame. Its MTB type design with 36 spoke 26" wheels.. Thanks.
