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”
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 Fat features 197mm x 12mm rear hub/wheel spacing. The front hub/wheel spacing is 150mm x 15mm.
Can you set up the LES Fat 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.
What wheel sizes are compatible?
The LES Fat is compatible with 26”, 27.5” and 29” .
What is the thread pitch on the rear axle?
We use a 1.5 thread pitch on the rear thru axle.
How wide of a tire can I run on the LES Fat?
For 26” wheels with a 60-90mm rim, you can fit tires from 3.8”-5”

For 27.5” wheels with a 60-90mm rim, you can fit tires from 3.8”-4.5”

For 27.5” wheels with a 38-55mm rim, you can fit tires from 2.8”-3.25”

For 29” wheels with a 38-55mm rim, you can fit tires up to 3”. You can also build up standard 29” wheels on to 150mm and 197mm hubs to run more conventional trail tires (2-2.4”).
What is the size of the seatpost?
30.9mm
What is the size of the seat clamp?
34.9mm (or 35mm as some manufacturers call it)
What is the seat tube insertion depth on the LES Fat?
S - 245mm

M - 230mm

L - 270mm

*Please check seat post measurements carefully before installing the post.
What lower headset cup should I use?
If you are using 29 tires with the rigid fork, 27.5” Fat with a rigid fork or a Rockshox Bluto suspension fork we recommend the Zero Stack lower headset cup.

If you are using a Manitou Mastodon suspension fork the 10mm external lower headset cup is necessary on size medium and small frame. Size large can use either the zero stack or 10mm.

If you are using 27.5 tires we recommend using the optional 10mm lower headset cup.

If you are using 26” Fat tires we recommend using the optional 18mm lower headset cup.
What front derailleur does the LES use?
An e-type side-swing style front derailleur - Shimano produces the e-type side-swing front derailleur in Deore
What crank and bottom bracket will work with my bike?
Any fat bike specific (197mm rear spaced) cranksets will work when paired with a 132mm press-fit BB. If the crankset you wish to use does not offer a pressfit BB option, Enduro, e-thirteen, and RaceFace offer pressfit BB cups compatible with 30mm spindles. Shimano, FSA, Chris King, Enduro and RaceFace offer pressfit BB cups compatible with 24mm spindles.
What is the narrowest Q-Factor crank I can run?
The LES Fat can run cranks with a minimum Q-Factor of 210mm. This is similar to the Q-Factor on bikes designed for the narrower 170mm rear hub spacing.
What is the maximum size chain ring I can run?
36t
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?
180mm
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 travel fork can I use?
The LES Fat was designed for suspension forks with travel between 90-120mm.
What is the fork offset?
51mm
How do I allow for multiple headset stack heights when cutting the carbon fork steer tube?
When installing your Pivot carbon fat bike fork, it is important to note that the steer tube should be cut long enough to allow for the use of the 18mm lower headset cup. If you are setting your bike up with the zero stack cup, placing an additional 15mm spacer on the steer tube when measuring will ensure that it is long enough to take advantage of the versatility of the LES Fat.
Is the LES Fat a good choice for bikepacking?
Yes, the integrated rear rack mounts make this bike great for bikepacking. Please consult with the rack manufacturer for clearance and fit details.
Can I mount a chainguide on the LES Fat?
Yes, the LES Fat features ISCG05 mounts, most upper guides on the market will fit.
How many bottles can I fit on my bike?
There are three bottle cage mounts on the LES Fat.
What are the torque specs?
A detailed PDF of the torque specs can be found in the Tech Specs section.
