Has anyone ever built a 29" off road tandem? Could a triple clamp fork be used to run 29" wheels (disc I'd assume).

Would it work with a 20x16 frame?

Vicious cycles do one, called the jeepster. Can't answer your other questions though.

To quote a line from The Usual Suspects - "There's nothing that can't be done."

Having said that, limiting the travel of a DH fork isn't likely to be a simple task. Speedgoat did some internal mods on a Shiver SC to set it up on the original Asylum proto. It required parts from a few different forks, and when I asked Chris about potentially duplicating one he didn't really want to discuss it (liability issues).

Whitebros can use the 150mm internals in their 180mm fork, it's all it takes. Or even 130mm internals in a 150mm fork, that should suffice as well. I discussed this with them regarding a possible 30" DH project in the uncertain future. Drop them a line, if they can make it work for you. Most people at WB ride 29" themselves, and will try to make something work for you. If they really really really like you, perhaps you could persuade them to make a slightly lengthened version of their 26" tandem fork. Don't tell them I sent you! WB has always offered 29" worthy forks when others let us down, they deserve your business just a bit more than some random other fork company.

I'd say, if you're really going at it, have a frame built around a 165mm rear hub, for wider spaced flanges and thus a stronger/stiffer wheel. Smartly bent chainstays will make it work with the stoker's narrow q-factor.

Wes Williams (Willits Brand Bicycles) has built several 29" tandems from both steel and ti. White Brothers could easily make the fork, all depending on what configuration you're looking for. I've been riding a BW 1.0 with a 20mm thru axle (on my Leviathan), and I think it might be suitable for tandem use.

Hey I'm looking at getting the 20mm thru axle as well. Can you tell the difference over a QR fork? Thanks

Schweet! Seems like WB has the most interchangability on the market - sorta like Marzocchi used to have.....
