The Lithic Fat Fork is a lightweight, versatile carbon option for fat bikes. This is a fork that Otso customers use for fat bike racing, bikepacking, and winter exploration. The 485mm axle-to-crown makes it compatible with suspension-corrected frames in place of a 100-120mm suspension fork. It has clearance for 26” x 5.4” tires and three-pack mounts for exploration, while the 740g weight makes it a light option for shorter fat bike races.
