When Stan's NoTubes first unveiled its Hugo 52 rim design, it inspired unlikely murmurs of approval and even excitement throughout the mountain bike industry. The excitement surrounding the Hugo 52 wasn't surprising because of its creator Upstate New York based Stan's had long since established its reputation as a pioneer of new tubeless technologies but more for the segment of mountain biking it created the aluminum rim for. Fat bikes have spent more time out of view as they plow through slush and mud than exploring the cutting edge of mountain technology, but the Hugo 52 27. 5in Boost Wheelset's advanced rim profile, developed to manage the difficulties associated with running fat bike tires tubeless, has firmly changed that sideline reputation.Managing the width of fat bike tires is the primary issue that most rims address less than satisfactorily, so Stan's decided to shape the Hugo's bead into a more rectangular shape, using low profile sidewalls to hold the outsides of the tires in place with a raised center box section. The raised center sits at the same height as the outer edges of the rim, which allows for a wider contact area, anticipating aggressive riding where harsh hits with unyielding trail furniture feature heavily in a day. By spreading the impact over a larger area, your tires are more likely to emerge unscathed from a big day of snow, rock, curbs, and any other terrain you feel compelled to tackle. This system also helps to separate the tire beads so they can work more efficiently, allowing the rim to better manage forces throughout a ride. Stan's also chose the Hugo 52 to debut its Bead Socket Technology, a well known fixture on many of its other rims but the first fat rim to boast the renowned system, which allows for easy inflation and dependable sealing, while working seamlessly with the Hugo's rim profile. Plus, if you still have an affinity for tubes, for nostalgia's sake, you can easily run the Hugo's with tubes and benefit from th...
