We may be heading to Arizona next week to test ride a Davis Double tandem. I talked with Bob Davis today and he told me that he does not have a frame our size available for testing. We use and XL/MED Santana and it is a good fit for us. We are also testing the Calfee and the Beyond later on. Our question is: Will we be able to do a fair evaluation of he bike even if the fit is not ideal?
