Otso Fenrir Ti Review

Jul 2023 · Neil Beltchenko

Find our complete Otso Fenrir Ti review after 550 miles of use while bikepacking, gravel grinding, and trail riding in Utah and Colorado...

Highs
  • Has more MTB steering characteristics (more trail) than most drop-bar MTBs, so it holds a line better and feels more stable

  • Tune-able geometry with tuning chip, which also allows the bike to be post or flat mount

  • Very comfortable ride quality without sacrificing performance

  • Good tire clearance for 29 x 2.6″ rubber (and should easily fit 2.8″ in rear tuning chip position)

  • Pretty light for a metal bike at 23.45 pounds naked with pedals

  • Loads of mounts and bikepacking provisions

Lows
  • Funky sizing and build options

  • Complexity and options can be frustrating to dial in the bike

  • Dropper should be standard, and 31.6 diameter post is overkill

  • Expensive

  • 1x-specific will be an issue for some folks

  • The middle tuning chip should be included
