Tested: Squamish, BC (8 Months), Durango, CO (2 Months), Phillipsburg, MT (1 Month). Ridden on steep rooty jank, all-day alpine grinds, flow trails, XC trails, and a bit of bike park. Rim: 27.5 DT Swiss ex471 (25 mm inner width) on 160 mm travel bike. Run only in the rear with a 2.3 Maxxis DHR2 DD, 21-27 psi. Rider: 6'1, 170 lbs. Flat pedals, upright/slightly off the back style. I hate (read: am terrible at) pedalling so pump/jump whenever possible. Huck Norris was one of the first companies to offer a foam insert to help mitigate some of the problems...
