WPL ForkBoost Bike Suspension Lubricant is an instant bicycle suspension performance booster. WPL ForkBoost lubricates and cleans bicycle suspension seals to eliminate stiction, remove dirt, and lengthen lifetime of the seal. Apply ForkBoost externally to the dust seals of bike suspension by coating the stanchion, pumping the suspension, and wiping away extracted dirt. ForkBoost is fully compatible with rubber and rubber derivatives, causing no risk of damage to the seals, seal swelling or cracking. Use ForkBoost internally during fork rebuilds, to soak foam seals and cut grease to specified thickness.
