Product: OilAbsorbent Fork Sponge Rings Key benefits Extends fork life: absorbs and retains lubricating oil to reduce metalonmetal contact and prevent premature wear of the front fork. Keeps performance consistent: continuous oil storage around the fork tube helps maintain smooth travel and damping. Easy maintenance upgrade: simple replacement or install during routine fork service to restore lubrication and reduce seal wear. What it does Made of density imported sponge that soaks up and holds fork oil. Sits around the fork inner tube to maintain a lubricating film and limit dry rubbing between moving parts. Reduces friction and wear, helping prolong the service life of your suspension components. Compatibility and sizing Available sizes: 32 mm, 34 mm, 35 mm, and 36 mm. Select the sponge size that matches the inner tube diameter of your fork for a proper fit. For example, if the inner tube is 30 mm, select the 30 mm sponge diameter for fit and performance. Designed for use with standard front fork inner tubes (match sponge diameter to your fork inner tube diameter). Material and performance Material: imported, density sponge for strong oil absorption and longterm durability. Performance: absorbency and storage capacity ensure a steady supply of lubricant to the fork tube surface. Practical use scenarios Routine fork service: worn sponge rings when overhauling forks to restore proper lubrication and reduce seal abrasion. Offroad or mileage riding: use to help protect forks subjected to heavy use, mud, and repeated compression cycles. Workshop inventory: stock multiple sizes for quick maintenance and customer service on a range of fork diameters. Why choose these sponge rings Straightforward, proven function: they store oil and deliver it where forks need lubrication most. Broad size selection to cover common fork inner tube diameters. density imported sponge balances absorbency with durability for reliable, longlasting performance.
