On the right course, nothing is faster than a hardtail, and nothing delivers the stiffness to weight ratio and raw speed as a Pivot LES SL. The LES SL is engineered to the Nth degree to deliver the kind of handling, extreme power transfer and weight that transforms every last watt of output into a race-winning performance.

  • Super-light, ride-tuned, carbon frame

  • Frame weight (size medium) is 2.3 lbs (1045 grams)

  • Ultra-lightweight carbon dropouts

  • Integrated headset for a lighter frame and lighter overall system weight

  • New-school hardtail racing geometry

  • Optimized Pivot Cable Port System for hassle-free, full-length, internal cable routing

  • 1x, 2x compatible

A tenth of a second gained here, a hundredth there, over and over across the length of an hour and a half long cross country race really add up at the finish line. The LES SL is up to three-quarters of a pound (that’s 300 grams!) lighter than it’s already svelte predecessor making it a racer’s dream that can turn seconds saved into minutes – all while retaining the quality and handling that has pushed Pivot athletes to cross country race wins at the elite level across the world. With new carbon dropouts, an integrated headset and new layup schedule utilizing Hollow Core Molding Technology and cutting edge carbon materials, the LES SL is by far the lightest hardtail we’ve ever built. Pivot’s race-winning hardtail legacy takes a quantum leap forward with a lighter, faster and sharper-edged tool with only one goal in mind: getting from point A to point B as fast as possible.


An ultralight hardtail with the rigidity of a wet noodle and unrealistic weight limits might look good on a scale, but they don’t perform under high wattage producing athletes out on the race course. Incredibly light at 2.3 lbs (1045 grams), the LES SL offers best in class stiffness to weight ratio and power transfer with laser-focused yet predictable handling. Our engineers managed to cut those grams while retaining that legendary Pivot ride quality and compliance that the LES line is known for – the kind that saves energy over the long haul and keeps the bike planted and predictable over all surfaces. The LES SL is the perfect hardtail trifecta of lightweight, stiffness and ride quality that lets racers excel at the highest levels.


When a bike racks up wins and course records in races around the world and is the weapon of choice for our World Cup XC, Tour Divide, 24-Hour racers every time the course is smooth and fast, you know that geometry is dialed. That’s why the LES SL retains the same great fit and handling that has made the LES a favorite with our elite racers across multiple disciplines. New school cross country race geometry relies on slacker head angles, shorter stems and longer reaches for the kind of stability that excels over the longest races and technical World Cup race courses with razor-sharp agility that makes it a short track racer’s advantage.


An optimized layout of Pivot’s innovative Cable Port System on the LES SL means perfectly clean, rattle free cable routing every time. Not only is it incredibly easy to service and route but it’s compatible with all drivetrain types and dropper posts that are quickly becoming all the rage with cross country racers.



Which size bike should I purchase?

To ensure the best sizing, we recommend that you visit your local Pivot dealer to get a professional fit and refer to our geometry chart to check your measurements. However, we can provide a rough guideline: 


Small: 5’5″ – 5’9”

Medium: 5’9” – 5’11”

Large: 5’11”– 6’3”

X-Large: 6’3″ +

Can I use a dropper post with this frame?

Yes, internally routed dropper posts are compatible with the LES.

How much does it weigh?

Variables in frame size, discrepancies in scale calibrations, and method of weighing (with or without pedals and such) all lead to inaccurate comparisons, so we choose not to publish our bike weights. Pivot bicycles are among the lightest available, but the weight is only one of many factors that make a great bicycle. Other aspects such as frame stiffness, strength, durability, and ride quality are just as important as weight to our engineers when designing our Hollow Core Carbon and aluminum frames. Instead of comparing grams online, we suggest you visit your local Pivot dealer and see our attention to detail, smart, high value spec, and class leading features. Bring a scale if you’d like, but take just one demo ride and you’ll feel why Pivot Cycles are the most well-rounded, highest performing bicycles on the market and in many cases, yes, it’s the lightest as well.

What dropper post length should I use?

There are limitations that each dropper post have for each frame size based on the rider’s saddle height, so it is important to check fit before choosing the travel and model of dropper post for your LES. Use the Dropper Fit Guide under the Tech Specs section to help identify the right post length.

What is the hub/wheel spacing?

The LES uses Boost 148mm x 12mm hub/wheel spacing. This hub design has wider flanges, so you cannot change the end caps to convert an existing 135mm, 142mm, 150mm, or 157mm hub.

Can you set up the LES as a single speed?

Yes, the Swinger II dropout system makes it easy to switch between geared and single speed set ups. The LES comes spec’d with alloy hardware and is set at a fixed location. The Swinger II adjustable hardware kit includes everything you need to make the system fully adjustable for single speed use or to simply adjust the chainstay length for increased tire and mud clearance.

How wide of a tire and what size wheels can I run on the LES?

On 29” wheels we recommend tires up to 2.3” with (up to) 28mm maximum inner width rims.

For 27.5″+ wheels you can use tires up to 2.8” with (up to) 40mm maximum inner width rims.

Rim width and tire manufacture sizing call outs and tire inconsistency can result in huge difference among both tire brands and individual tires. We suggest you check the fit with your chosen rim and tire combination to make sure it has proper clearance before riding

What is the thread pitch on the rear axle?

We use a 1.5 thread pitch on the rear thru axle. You can order one through our online store.

What cranks will the LES accept?

The LES will accept all cranks designed for the BOOST system and compatible with a Press Fit 92mm bottom bracket. BOOST system means that the rear hub spacing is 148mm and the chain-rings have been shifted out approximately 3mm from where a tradition crank designed for a 142mm rear hub would be so that the chainrings will line up properly with the new position of the cassette on the 148mm rear hub.

Can I use a non-Boost crankset?

You can use non-Boost:

Race Face Next SL 1x cranks

Shimano XT and XTR 1×11 cranks (with 30t or 32t)

Shimano XT and XTR 2×11 cranks (with 24t/34t or 26t/36t)

There may be other 2x non-Boost cranksets available that will work, thought it will depend on the chainline and chainring size. If the chainline is not out far enough, the front derailleur clearance may be tight when shifting in to the small ring – the front derailleur mount has been shifted outwards to accommodate the Boost design.

What is the size of the seatpost?


What is the size of the seat clamp?

34.9mm (or 35mm as some manufacturers call it)

What front derailleur is compatible with the LES frame?

An e-type side-swing style front derailleur – Shimano produces the e-type side-swing front derailleur in Deore & SLX for 10-speed drivetrains and XT & XTR for 11-speed drivetrains.

What crank and bottom bracket will work with my bike?

All cranks designed for the Boost system and use a Pressfit BB92 bottom bracket will work on your LES.

What is the narrowest Q-Factor crank I can run?


What is the maximum size chain ring I can run?


What travel fork can I use on my LES?

The LES SL was designed for 100mm to 130mm fork travel. 130mm is the maximum travel length to be used on the LES SL. We use the new FOX 32 Step Cast 100mm fork in all our complete bike builds. This fork is a 29” race-specific fork designed for 29” wheels with up to 2.3” tires and is NOT compatible with 27.5+ tires. 

What is the fork offset on the LES?

The Fox 32 100mm Stepcast we spec on all the standard builds has a 44mm offset.

The Fox 34 120mm fork we spec on the 27.5”+ builds have a 51mm offset.

What headset do I need?

Zero stack (ZS) 44mm top and ZS 56mm bottom (or a Chris King Inset 2)

What is the largest rotor I can fit?


Do I need a rear brake adapter?

No rear brake adapter is needed for a 160mm rotor. If you would like to put a 180mm rotor on, you will need a direct mount post-to-post adapter.

What are the torque specs?

A detailed PDF of the torque specs can be found in the Tech Specs section.
