This thing eats up chunk and maintains traction like nobody's business - you'll feel the difference immediately on technical trails. The factory series represents Fox's highest level of performance and craftsmanship. Whether you're charging through rock gardens, hitting drops, or just want the best suspension performance money can buy, this Float X shock delivers pro-level performance that'll transform your ride.
