With plus-sized bikes on the rise, many riders are on the hunt for wheels that are strong, lightweight, and fast rolling. As pretty much anybody can imagine, it's not easy to combine these three factors. For years, a mountain bike wheel was strong or light, but never both. Add high quality internals to the mix, and you might as well be looking for the Holy Grail. Fortunately for bike lovers, technology is a neat thing that exists. We don't exactly understand how Industry engineered these magical wheels, but we're glad they did.
The Back Country 450 is a magnificent wheel. The rims feature I9's second generation tubeless technology with improved tire retention and a larger contact area. The front hub has dual bearings that each have external o-ring seals and straight gauge spoke drilling. The rear utilizes four bearings, external Teflon seals, and a silicone freehub seal. Driven by 120 points of engagement and a dual 3 pawl system, the 30's deliver three-degree engagement. At just 2025 grams, it's hard to deny I9's plus-sized prowess.
