A Faster Wheelset
Always striving to create wheelsets to cover the needs and wants of every rider, Industry Nine is pleased to introduce the BackCountry450 to our Torch system wheelsets. Designed as a "plus size" rim to accommodate 2.8" to 4.0" tires the BackCountry450 is a true, singletrack-bred wheelset ready to challenge any terrain. Following the lead of our second generation mountain rim family, the BC450 takes design cues from the Ultralite235, Trail245 and Enduro305. What that means to the rider is a 45mm inner width hoop that sets up and retains the tire with ease and confidence. Whether building a faster wheelset for the Fat Bike or putting the crowning achievement on a new plus rig, we can lace the BackCountry450 to both the 32h Torch Mountain or FatBike System chassis, the BackCountry450 is poised to make any bike an all new ride.
By making the rim bed wider the tire sidewalls sit in a more vertical position increasing sidewall tension thus creating a firmer tire contact. This higher tension lets you run lower pressures versus narrower rims allowing the tire to conform more naturally to the terrain and increases the contact patch. More tire on the ground, more traction when it matters.
Like all of our System Wheels, you can customize your hubs and spoke colors in any combination for an additional fee. We offer 11 custom anodized colors: Orange, Purple, Turquoise, Lime, Gold, Green, Blue, Red, Pink, Silver and Black. Visit our AnoLab Custom Wheel Designer to customize your i9s.
