01 Overview

Conquer the Dirt

One thing that makes gravel such an exciting discipline is that there are so many different types of gravel styles and conditions a rider can face. The Factor LS meets all those challenges with the full intent to be the fastest, super capable gravel racing bike for pro and amateur cyclists alike. Made using lightweight carbon that can provide both comfort and durability, the LS represents your ticket to adventure.





    02 Benefits
    Lightweight and responsive

    When designing the LS, we were laser focused on keeping the frame lean, light, and responsive without being distracted by unnecessary add-ons. This is a bike that begs to be ridden at race speeds whether it’s rough terrain or smooth tarmac. Nimble and durable simultaneously, the Factor LS easily segues from city streets to forest trails and back again without missing a beat. The rigid chasse helps it climb like a dream and descend with confidence.

    Designed for fast gravel rides

    The perfectly balanced geometry combined with the frame’s stiffness translate into powerful accelerations. With shorter seat stays and refined steering trail, racers maintain the ability to react in a heartbeat to the often unpredictable dirt road conditions while still running tires with appropriate volume for fast riding on rough gravel.

    Broad Compatibility

    Focusing on being fast whether riding over smooth tarmac or rough gravel, the LS offers a wide range of compatibility. Optimized to fit up to 40mm tires, the LS can easily tackle tough gravel races, or fast road rides when paired with a 30-35mm tire. The frame is also compatible with 1x and 2x groupsets as well as both electric and mechanical shifting. This versatility allows the rider to find the perfect setup for any riding style.

    03 Features

    Go further faster on mixed terrain adventures

    The Factor LS is all about our love of cycling and the places it can take you. Whether on smooth, fast pavement or grinding through loose gravel, it’s a bike that will keep you planted and having fun.

    Carry Speed, Not Weight

    Long grueling days in the saddle require the lightest and fastest gravel set-up. The LS is designed to carry what’s essential with mounts available for three bottle cages, a top tube Bento Mount, and space for a sleek frame bag.

    Keeping your options open

    With our modular cable routing, the LS can accommodate electronic and mechanical shifting drivetrains. The frame also works both with 1x and 2x setups, which will allow riders to have the perfect gearing for their chosen adventures.

    Frame bag compatibility

    For those days in the saddle that do last into the night, having the capacity to carry extra clothing and nutrition makes a neatly tucked in frame bag an ideal addition without turning into an unwanted and destabilizing weight.

    The best designs are the simplest

    Taking a leaf out of our O2 road bike book, the LS shares many of the tube shapes with the added value of our kinked pencil thin seatstays and standard 27.2 seatpost. They help to dampen road vibrations for added comfort.

    T47 threaded bottom bracket

    The T47 standard for threaded bottom brackets ensures a secure fit and easy maintenance. It allows for the use of a wide range of crank spindle diameters and helps keep the bottom bracket shell robust for exceptional power transfer.

    Hit the dirt

    The Factor LS has been optimized for 40mm tires and can accommodate up to 43mm.

    Electric and mechanical compatible

    Building the perfect bike means being able to fit your components of choice. The Factor LS accepts both electric and mechanical groupsets so you can choose which option works best for your riding needs.

    In my opinion, the perfect gravel bike will be as close to a road bike as possible, and I think the LS frame is very close, if not spot on. When you look at the frame you can tell that Factor has used some of the know-how from the O2 frameset and made more room for bigger tires, added additional space for bottle cages and made the frame more resistant to small impacts from rocks and other hard objects.
