I built up the 24H version of these for the rear on a single bike, but depending on weight 24H might not be good for a tandem. I don't know of a suitable 36H deep alu rim on the market right now. If anyone does, please reply. I'll run out of my stock of Kinlins in another year or two.
About 25 years ago, on a single road bike, I used to ride a pair of Campagnolo Zonda alloy deep-rim 28H wheelset. These were undestructible. And I would not have been afraid to ride with them on the tandem. But I sold them long ago, and Campy does not make the same wheel anymore.
