And as
I said, my MTB and roadie are just about the same height in terms of frame size and bottom bracket to the saddle. I'll be more than happy to provide measurements and photos.
As for the tubes, I also mentioned that while they are the same in height, the widths between a road tube and MTB tube are different but the heights are nearly the same. Yes, the 29er tubes for a MTB are massive, but a 29er wheel is extremely close in size to that of a roadie wheel. I'll be happy to provide photos and measurements of that as well.
