with a USD fork in order to fit a 29" wheel all that's needed is to limit the travel a little bit so the wheel doesn't bottom into the lower crown. 29ers don't need as much travel anyway since the bigger wheels roll over terrain better so it works out really well. I'm sure the only difference in the 26 and 29 Dorado is a travel reducer spacer in each leg, just like the Maverick fork. I highly doubt they'd invest a lot of R&D into a segment as niche as 29'er DH. Cool to have options none-the-less.

750mm=29.53" FYI...wait until the fall.
