Taking design cues from I9's highly popular Ultralite 235, Trail 245, and Enduro 305 wheels, the Industry Nine Back Country 450 27.5 Plus Wheelset strikes the optimal balance between efficient climbing prowess, sturdy construction for technical trails, and widened footprint for optimal traction on your plus-sized or fat bike. Boost axle compatibility significantly stiffens the wheelset, providing precise tracking and unflappable confidence when barreling across rocky trails.

This wheelset features a massive 45mm internal width, accommodating 2.8in plus-sized tires, all the way up to gigantic 3.8-inch fat bike tires. However, that's not to say it's stout stature holds you back with excess weight on the trail. Tipping the scales at 1950 grams, the Back Country 450 Wheelset is certainly competitive, especially considering its widened footprint on the dirt. Ultimately, wider wheels accommodate lower tire pressures for unrelenting traction on the trail (with plus-sized tires) and unbelievable grip over loose sand/snow (with fat bike tires).

Tried-and-true aluminum construction ensures robust durability for ripping across technical sections of trail littered with rocks and roots. Each wheel is laced with 32 spokes for dependability on your plus-sized trail whip or burly fat bike. Industry Nine's Torch hubs deliver near-instantaneous 3-degree engagement for easily powering up and over trail obstacles. This wheelset is available with a HG driver for Shimano/SRAM 9/10-speed drivetrains or a XD driver for SRAM's cutting-edge 11/12-speed drivetrains. It comes tubeless-ready, with pre-installed rim tape and Presta valves.

  • Gargantuan wheelset for plus-sized and fat bikes
  • Sturdy aluminum construction for optimal strength
  • 45mm internal width accommodates 2.8 to 3.8-inch tires
  • Stealthy styling upgrades your plus-sized/fat bike
  • Industry Nine proudly handcrafts wheels in the USA
