This is the Ultimate Guide to the Pivot Les. The Les and all of its versions deserved an entire page for all the details.
When looking for the ideal Single Speed frame I discovered the Pivot’s hardtail option. Not only could this frame be a fantastic geared hardtail, it can be coverted to a Single Speed with sliding dropouts but also a Fat bike that will take almost any tire size.
In addition to the above bike styles it can also be fitted with 29 inch wheels, 27.5 inch, and 27.5 inch plus wheels.
As you will learn with all of its versatility this there is nothing less about this frame except the name.

Introduction
Pivot Cycles was established in 2007 by Chris Cocalis in Tempe, Arizona, and the Les is their hardtail mountain bike offering. The name is a play on words pivot and less since it is not a full suspension.
Originally announced and sold in late 2012/early 2013. The frame geometry and build have remained almost unchanged, which means they pretty much got it right from its introduction.
V2 of the Frame
In late 2016 a 2nd version announced. This update increased the wheel/hub spacing from 142mm to 148mm (boost) spacing. In addtion, some of the carbon layup changed and support for Di2 shifting was added. This updated frame is referred as V2.
Currently (as of 2020) the Les is available in three frame types, the Les, Les 27.5 and Les Fat.
- Les = Geared or Single Speed, 29″/27.5+ wheels
- Les 27.5 = Race Version, 27.5″ wheels, super light
- Les Fat = Fat Bike Version
Les
The Les is the original and was designed to be a versitle. 29″ or 27.5 plus bike. Using a patented rear dropout system the frame can be converted to a single speed.

- Referred to as “The Les”
- Can be configured as a Single Speed
Les SL
This is the newest addition to the family. Released in 2019 the SL focuses on being super light. It is available October 1, 2019
Highlights
- 29″ Wheels (not 27.5+ capable, I think)
- Designed for Racing

- 3/4 pound or 300 grams lighter than the Les
- NOT Single Speed Compatible
Les 27.5
- Built for 27.5 wheels.

Geometry & Specs
Les Frame Details
Frame first released in 2012
Internal Cable Routing
Direct Mount Front Deraileur
Pressfit BB92 bottom bracket
The Pressfit 92 allows the frame to be wider on the bottom tube, wider on the down tube, wider stance on the chainstays. This really stiffens the bottom bracket area so that the frame will absorb more of the bumps without having to resort to a stiffer carbon layup.
Wheel Spacing (Boost)
V1 of the frame is shipped with a full carbon 142mm by 12 carbon thru axle design.
V2 of the frame has 148mm by 12 boost spacing
Convertible to Single Speed
The frame is convertible from geared setup to a single speed sing the swinger dropout system.
The swinger system comes with quick index adjust system so that you can easily adjust both sides identically. Keeping the wheel centered. The system does not allow the wheel to slide forward under chain tension. The conversion kit also comes with all the caps needed to cover all of the cable ports. The entire kit is a well thought out thourogh process to convert the bike to a single speed.
Rider Sizes
Rider Size can go down to the 5’5″ / 5’6″ with the small size

69 1/4 head tube angle
Very fast race bike that can handle more aggresive terain.
142 by 12 thru axle
Pressfit 92 bottom bracket
Dedicated Axel system so it can not convert to single speed, this saves about 100g on the weight of the frame. Les 27 was meant to be as light as possible
Les Fat Frame Details
The Les Fat is intended as fat tire specific. It was originally released early 2016 in a black (raw carbon) with blue accents color. It was then re-released in 2019 in a light blue color.
The only difference between the two different versions was color and components.
The frame geometry is the same between the two releases.
The Les Fat has 197mm x 12mm rear hub/wheel spacing. The front hub/wheel spacing is 150mm x 15mm.
