Factor's bike portfolio has grown significantly over the past 18 months, boasting a smorgasbord of new race offerings, which includes the expansion of its off-road line-up. Joining the all-road Factor Vista is the new LS, the company's first attempt at a bona fide gravel bike. It comes as no surprise that Factor has pegged the LS squarely at the racer, choosing to eschew the bump-softening gadgets of its rivals in favour of creating one of the stiffest and tactile riding experiences in the segment. We spent a few weeks putting the Factor LS through its paces over a selection of challenging terrain surfaces to establish where it sits in the gravel bike hierarchy.
