Pivot Cycles LES Fat – first look

Highly adjustable carbon fat bike

Pivot Cycles has just rolled out its first fat bike, the LES Fat. This new model features a full carbon frame and compatibility with 27.5+ and 29+ tyres in addition to the largest fat bike treads on the market.


Pivot did its best to cover as many tyre sizes and emerging niches as possible with this new model. The LES Fat uses the 197x12mm thru-axle standard and a 132mm-wide with a press-fit bottom bracket. It can accommodate 26in fat bike tyres up to 5in wide.

Like many other fat bikes on the market, the Pivot LES Fat is also able to accommodate 27.5+ and 29+. Pivot opted to built the LES Fat with sliding dropouts, dubbed Swinger II, that allow this fat bike to be run as a singlespeed or give geared riders the ability to fine-tune handling by adjusting the chainstay length to suit their preferences — the dropouts can be moved forward for nimble handling with smaller, 26x4in or 27.5+ tires, or slid back to make room for 26x5in or 29+ treads.

Pivot includes ZeroStack and 18mm lower headset cups with the LES Fat to make adjustments to front end geometry and preserve handling characteristics across wheel and tyre sizes.

The LES Fat is compatible with the RockShox Bluto fork and comes with Pivot’s own carbon fork. Like the Bluto, this rigid fork uses 150mm-wide front axle spacing.

The LES Fat uses the Pivot’s internally routed cable port system, which was introduced on the Mach 4 Carbon last summer. This modular routing system uses large, easy-to-access ports with interchangeable covers to allow for a variety of routing options — even accommodating Shimano’s XTR Di2 drivetrain.

Other notable frame features include rack/fender mounts, three sets of water bottle mounts and routing for a stealth-routed dropper seatpost.

The LES Fat will retail for US$2,599 for the frame, matching rigid carbon fork and headset with ZeroStack and 18mm lower cups. A single complete bike with an XO1 build will be offered for US$4,699. (UK and Australian pricing was not immediately available.)

Pivot expects to begin shipping framesets and complete bikes in two weeks.
