The lightest fork that FOX has ever built! Slim design for good compatibility with gravel frames. A complete optimization of design, materials, and oil volume. Compared to the previous FIT4 cartridge, weight savings were achieved while maintaining the same performance, ride quality, and adjustability. Available with either 40 or 50 mm of travel. Optimized 700c fork with plenty of space for tires up to 700x50 mm.
