FACTOR LS

Lightweight Gravel Race Bike

Refined and lean, the LS flies. With optimised stiffness for gravel, an ultralight 950g frame, and crisp race-focused handling, LS is a no-holds-barred gravel racer.

OVERVIEW

The gravel sector is as broad as the countryside in which the bikes are ridden.

Factor made a clear choice with the LS – no compromise. It isn’t trying to be every bike for every rider and it certainly isn’t made for bikepacking. This is a racer. Carry speed, not weight.

Long, gruelling days in the saddle require the lightest and fastest gravel set-up. The LS is designed to carry only what’s essential, with mounts for three bottle cages and a top tube. Want to know where to put your tent and stove? In the support car.

The LS is meticulously crafted, stripped back and solely focused on the essence of gravel racing: speed and grit.

Built to Conquer

Perfectly balanced geometry, low weight and high frame stiffness give the LS powerful acceleration and climbing, diverging from traditional, pack-animal gravel bikes. The LS offers the power transfer stiffness for aggressive riding to break away from the group, all while maintaining the compliance necessary to make your energy last.

The geometry of the LS is optimised around 40 to 43mm tyres, the preference of competitive gravel racers. Focusing on this size range allowed Factor to avoid the trade-offs that come with accommodating bigger tyres. The LS has shorter seat stays and steering trail to give racers agility similar to that of a road race bike, blended with the stability necessary for pushing the pace off-road.

Key Features

Securely mount a feed bag where it’s most aero and easiest to reach

Carry what you need to go self-supported all day and even longer

Sustain your epic rides with the option to carry a third bottle under the downtube

Saves the frame from damage in the unlucky event of the chain getting sucked around the chainrings

Absorb vibration and shocks to save you energy

TGE LS is compatible with both mechanical and electronic shifting groupsets and with 1x and 2x drivetrains, so the choice is yours
