>>1038557Well, there's the Salsa Fargo, which while not truly 29+, will fit a 2.4" wide 29er tire. And geo for drop bars! Definitely designed for offroad touring.
On the flip side, the Tumbleweed Prospector - pic related. It's a genuine 29+ bike - it'll fit a 29x3" tire. Or a 27.5x3.25". Or a real 26x4" fatbike tire. Standard 135mm rear dropout spacing and 135mm spacing for the front fork as well. Derailleur hanger for geared drivetrains but an EBB for single speed. Standard 73mm BSA threaded BB so you can use normal MTB cranks.
