Y'know, I sat down and worked the math on that one, and I gotta say, that's a pretty huge difference for 6 miles. Maybe the MOE brings it closer together, but 10 minutes difference for that distance is a head-scratcher - especially since one of the bikes shouldn't really be all that fast on pavement (the 29er w/ knobbies). Maybe if you had a whole bunch of short blocks with stop signs/stop lights at each intersection... Or a bunch of short, sharp risers to climb. If you are _that_ much faster on the mtb, and you want to sharpen up the performance of the Sam, you might take a look at the position of your saddle relative to the bb, the relative height of the bars, and see if some concessions are to be made. Sometimes it takes a little more riding to be efficient - I know the first day when I switch over from Quickbeam to Hilsen, things feel a bit pokey. Honestly, I'd also take a good stem-to-stern look at things that move - the wheels, making sure they roll smoothly and aren't rubbing brake pads, make sure they aren't somehow binding when in the dropouts. Also, are you using a different computer on each bike? Or, are you timing via watch? Ok.
