I have a Santana and a Trek tandem and would like to sell them both. The Santana is a 1995 Arriva w/S&S Couplers. Size Medium.  It comes with a suitcase the commercial airlines will accept so it is great to take on a trip. 

The Trek has been modified so it has independent suspension.

I am not very knowledgable about bikes so please reach out to me with any questions or interest.  I plan to take the best offer I get for both or either.
