The Factor LS Gravel Frameset - Form follows function

The LS frameset by Factor is designed for gravel riders who like to take part in long, demanding competitions or want to tackle routes with a lot of cumulative elevation. It is not designed for cycling tours with luggage, but rather for competitive use in small and larger groups.
The design of the carbon frame, which weighs only 950 g, is therefore characterised by optimum stiffness values and an aggressive geometry. Balanced handling and a steeper steering angle ensure that you can react in seconds to the special challenges of natural roads, such as potholes and stones. The very low-set bottom bracket compensates the large outer diameter of wide 700C Gravel tyres. The wheelbase was kept as small as possible so as not to impair manoeuvrability on gravel. In addition, the adjusted seat angle and the linearity of the stack/reach ratio allows a perfect fitting for riders of all heights.
Like the frames of the Factor OS series, the LS bridges the gap between a World Tour-tested geometry and the requirements of amateur racers. However, despite the integrated design, regular seatposts, stems and handlebars can be mounted, so you can easily adapt the bike to your needs.
The frameset was named for Larry Shahboz, who introduced Rob Gitelis (owner of Factor Bikes) and many others to the cycling community and supported aspiring athletes. He inspired the ethos that the Gravel community was founded upon--an ethos which is embodied by the functional design of the LS. Reduced to the essentials, this framework is focused on a single thing: to make you the strongest contender possible in Gravel racing.
