I just finished building my second set of DT Swiss 1.1(front) and 1.2(rear) on White Ind hubs for our new tandem. It's a complete Campy bike as well.
Previously we had a set of disc compatible DTSwiss on Wht Ind hubs which were great as well.
This set is a 32h build and weighs 1812gr w/rim strips.
I also race DTs on one of my singles and have never had a problem.
Got 18,000+ miles on a pair of Velocity Aeroheads (32H x 36H) with DT Revolution spokes, King hubs.
Run 25mm Maxxis Re-Fuse tires and have run 23mm. Our team weight is just below 250.
One minor issue: Broke one spoke nipple (alloy) on front wheel after almost 18K miles.
