Condition:
This Vir Fortis is an ex-display bike that's had light use and is in good condition, aside from some minor cosmetic marks. See the photos.
Vir Fortis is designed to go anywhere, big tyres and big wheels gives a massive amount of traction.
Vir Fortis is not just strong, it is light too: a medium frame weighing in at just 1550g and letting you float over the wildest trails like a cloud. It looks sharp: cables are routed internally to avoid snagging and keep things clean, and a single mounting point on the downtube gives you the option to add a bottle cage.
With a race-winning pedigree, Vir Fortis inspires you to explore the outer boundaries of the trails. Its slackened off geometry gives a characterful ride and is compatible with tyres up to a chunky 4.8". It’s carbon frame and fork gives precise handling and trail bike feel.
It has taken on some of the roughest rides in the wildest terrain, and come out on top.
