Pivot Cycles introduces what could be the most versatile big tire bike on the market in the LES Fat. Not just another fat bike, the key to making the LES Fat a go-to option in any season is the newly patented Swinger dropout system. So what is so revolutionary about this innovative feature? This simple-to-use design enables riders to quickly and easily change both chainstay length and bottom bracket height to accommodate 4” or 5” fat-bike tires as well as the newer 27.5”+ and 29”+ wheel sizes. The most important feature here is the geometry optimization for the correct bottom bracket height and the shortest chainstay length possible for each wheelsize.
The LES Fat maintains ideal geometry via the indexed adjustment arc of the dropouts – the bigger the wheel and the more clearance, the lower the bottom bracket. Choosing the shortest possible chainstay length gives riders a flickable, playful ride. Selecting a longer wheelbase and more tire clearance provides stability for heavy loads and messy conditions. Included with the frameset and complete bike are two headset cup options (Zero Stack and 18mm), for perfectly balanced front-end geometry at any wheelsize.
The full carbon frame of the Pivot LES Fat features leading-edge materials and our proprietary hollow-core, internal-molding process. This coveted technology enables Pivot to create an ultra-lightweight frame featuring slim top tube and seatstay profiles, as well as the largest downtube in the category. When combined with a 132mm Press Fit BB, the result is best-in-class power transfer and vertical compliance that makes epic rides comfortable and fun.
The LES Fat includes a Pivot-designed taper-steerer carbon fork with 150mm dropout spacing and is also RockShox Bluto compatible – one wheelset will work with both fork options. This identical spacing makes it easy for riders to transition between uses, whether they are gearing up for winter training, long distance touring or seeking more aggressive terrain.
Pivot’s goal is to enable riders to to use the LES Fat as their daily driver. With that in mind, 2x, 1x and singlespeed gearing compatibility makes the LES Fat an ideal choice in any terrain, and the LES Fat rear spacing is a generous 197mm with an innovative low Q-factor design (the lowest in the category) when built with the Pivot/E-Thirteen co-designed fat bike crankset. The combined gearing options and knee-saving Q-factor provide the best possible pedaling performance in high-cadence racing, training and trail-riding applications.
The Pivot Internal Cable Port System makes cable routing simple to install and maintain via large, easy to access ports and interchangeable covers. Easily switch between a variety of cable routing options for the cleanest installation. Additional details include integrated rear rack mounts, internal dropper post routing and 3 water bottle mounts – making the LES Fat the perfect choice for any big tire adventure.
