so you can run 29er tyres and road tyres.
One thing I appreciate about my Caffeine is that I can mount 26" mountain bike tires or 700C road tires (on different wheelsets, obviously) and my gearing stays essentially the same.

cyclocross tyres too 700x32c
road tyres too 700x23c

so of course, when you mount a 23c tyre on your 29er MTB
Can you find a rim that will properly hold both a 700x23 and a 2.35" 29er MTB tire? It seems like it would either be too wide for the one, or too narrow for the other.
As far as the BBU goes, it is (or at least in 2007 and 2008 it was) built on the same frame as the Caffeine F3, which is a mountain bike. You can surely take a mountain bike in the dirt, whether it's painted as a BBU and has trekking gears or it's painted as a Caffeine and has mountain gears.
