This is my first tandem to work on. Im updating a 26 burley softride tandem, gonna use it mostly with the wife for gravel epics and such. My main concern is wheels. I know that 40 spoke is prefered and advised.... iv got a real nice pair of Cane creek WAM wheels. Sturdy set up, but only 32 spoke. Is it crucial to run 40 or at least 36 spokes for this, or will my set up be sufficiant? Any help will be great!
