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.
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. The LS is optimized for 40mm tires and is compatible with both 1x and 2x electronic and mechanical shifting.
The perfect pairing
The Black Inc THIRTY-FOUR carbon gravel-oriented wheels were designed specifically with the LS in mind. Lightweight, durable, and offering a rim profile perfect for fast situations over mixed terrain, the THIRTY-FOURs complete this dream gravel racing package. The rim width accommodates wider tires ideal for going off the beaten path.
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.
