Why We Love It
Fenrir isn't your typical mountain bike. This one was designed from the trail up for bikepacking. Where most bikes can feel wobbly when loaded with a week's worth of gear, Fenrir rides confident and strong as ever. Build it with drop bars or flat bars, suspension fork or rigid fork, dropper post or rigid seatpost, gears or single speed, and a mechanical or electronic drivetrain. A tire clearance of 29” x 2.6” or 27.5” x 2.8” keeps the Fenrir rolling on rough terrain, while extra frame and fork braze-ons are ready to carry gear for days or weeks on the trail. Like all Otso bikes, the Fenrir has adjustable geometry via the patented Tuning Chip rear dropout system that makes the bike as adaptable as its rider.
