On our c/f Zona tandem we utilize King hubs, Velocity Aerohead rims and DT Revolution spokes; 32H front, 36H rear We do not have a disc setup.
Current rear wheel has 23,000 miles on it; the only issue is that rim needs replacing as we hit some debris pretty hard and wobberknockered the rim acouple weeks ago.
Front wheel have broken 2 spoke nipples around the 20,000 mile mark.
Highly recommend Velocity rims and CK hubs.
These are our everyday wheels and we weigh in at just under 250 lbs as a team.
Pedal on TWOgether!
