Ear-to-ear grins come standard with the Pivot LES Fat

The Pivot LES Fat is the world’s most versatile big-tire machine. Compatible with almost every wheelsize available, from fat bike to 27.5-+ to 29er, the LES Fat is a four season hardtail that can take you from singletrack to snow to sand without compromise.

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 us to create an ultra-lightweight frame featuring the largest downtube in the category and a 132mm Press Fit BB for best-in-class power transfer.

Our patented Swinger II dropout system works with all plus / fat bike wheelsizes. Choose the shortest possible chainstay length for a flickable, playful ride or choose a longer wheelbase and more tire clearance for stability with heavy loads and in messy conditions. 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. Included are two headset cup options (Zero Stack and 18mm), for perfect front end geometry at any wheelsize.

The LES Fat is RockShox Bluto compatible and includes a Pivot designed carbon fork with 150mm dropout spacing – one wheelset will work with both options. 2x and 1x gearing compatibility makes the LES Fat an ideal choice in any terrain, and the LES Fat rear spacing is 197mm with an ergo-friendly low Q-factor design when built with the Pivot/E-Thirteen co-designed fat bike crankset. The Pivot Cable Port System makes internal 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.

Swinger II Dropout System

The LES Fat features our patented Swinger II dropout system, enabling you to run almost any available plus or fat bike wheelsize, easily switch between singlespeed and geared drivetrains and choose your chainstay length based on conditions and desired handling characteristics. With the option to run every tire size from 26 X 3.8, 26 X 4.8, 27.5+, 29+ and anything in between, your bike is really a quiver of options that take you into any season and any condition.

Riders also have the option to set chainstay length within the Swinger II system. The shortest possible setting gives you a flickable, playful ride previously unknown in the big tire category – we feature the shortest chainstays for every wheelsize category. Adjusting for maximum wheelbase and tire clearance (the LES Fat accommodates rubber up to 5- in width) gives you an incredibly stable ride for heavy loads and messy conditions.

Great Geometry at Any Wheelsize

No matter what wheel/tire combination you choose, great handing characteristics are an imperative. The Swinger II dropout system allows the LES Fat to maintain ideal geometry via an indexed adjustment arc designed into the dropouts – the bigger the wheel and the more clearance you choose, the lower the bottom bracket.

In conjunction with the adjustable rear dropouts, we’ve also accounted for how changing wheelsizes affects the front of the bike. Included with every LES Fat frameset and complete bike are two lower headset cup options – when using a 29+ wheelset or the Rock Shox Bluto suspension fork, choose the Zero Stack option. For 26- wheel options, choose the 18mm cup.

Custom Designed Fork and Bluto Compatibility

The LES Fat frameset includes a Pivot designed carbon, tapered steerer rigid fork that easily accommodates any wheelsize with clearance to spare. This full carbon fork features 150mm dropout spacing – the same spacing as a RockShox Bluto suspension fork. Riders who choose to switch between the supplied rigid fork and a Bluto fork will only need one 150mm compatible wheelset to work with either option.

Ideal Gearing and Ergonomics

Ergonomics and gearing are the key to making a big-tire bike into your daily driver. We at Pivot expect to see the LES Fat in a wide variety of terrain and riding surfaces and in everything from racing events to multi week tours. For the best performance in both high and low cadence conditions, we’ve made sure that the LES Fat is both kind to your knees and that it accommodates a wide variety of 1x, 2x and singlespeed gearing set-ups.

Massive chainstay clearance (up to 5- tires) is made even more useful with a q-factor and chainline much closer to that of bikes designed to cleat only 4- or smaller tires. You will find 197mm rear spacing on the LES Fat paired with a 15mm narrower knee-saving q-factor when built with the Pivot/E-Thirteen co-designed fat bike crankset that ships on every LES Fat complete bike.

2x and 1x gearing compatibility makes the LES Fat an ideal choice in any terrain. The LES Fat complete bike comes with a 1x set up, but the crank spider is 2x compatible. The frame features a low profile e-type mount included with both the frameset and complete bike that works with Shimano’s sideswing front derailleur.

For those that prefer the simplest solution, the Swinger II dropout system also singlespeed compatible – no need to switch dropout hardware.

Pivot Carbon Frame Design

The full carbon frame of the Pivot LES Fat features leading-edge materials and our proprietary hollow-core, internal-molding process. This coveted production technology enables us to create a best-in-class frame with the lighter, stiffer, stronger qualities needed to make a do-anything fat bike. In order to support a wide range of wheelsizes, while tracking and accelerating beyond expectations, the LES Fat features the largest downtube in the category, as well as optimized layup structure, top tube and seatstay/chainstay shaping. This proprietary design gives the LES Fat best in class power transfer and the vertical compliance that makes epic rides comfortable and fun.

Pivot Cable Port System

Additional foul weather advantages are found in the Pivot Cable Port System. Internal routing for any component is easy to install and maintain via large, easy to access ports and interchangeable covers. Riders have the ability to switch between a variety of cable routing options, allowing for the cleanest possible installation. Rest easy knowing that no matter what components or gearing you choose, now or in the future, we have you covered.

Versatile and Functional Details

Additional essential details include beautifully integrated rear rack mounts, internal dropper post routing for extreme terrain and 3 water bottle mounts, making the LES Fat the most capable adventure bike you can get
