Beercan, nice bike! I was thinking more of the hardtail steel thing with a Reba on the front. The general "consensus" is, as would be the case with larger wheels, the big wheels roll over smaller obstacles better. Can you notice a difference between 26 and 29 at places like Morris Bridge, say Gatorbait, Indian and HB Ridge with the roots systems that are on those trails? Also, I see the Bontrager XR on the front and what looks like a WTB tire on the rear. Have you tried other tires? Had good luck with these tires? Thanks again for the reply.
