Unlike low-grade replica seals that rapidly tear, harden, or weep under intense hydraulic pressure, these premium Made in Italy BikeMaster seals are engineered from an advanced elastomer compound that exhibits high resistance to structural fork oil additives. Precision-ground sealing lips automatically adjust to internal pressure spikes during heavy front brake compression and sudden extension cycles. This mechanical configuration establishes a reliable positive-containment boundary around your 39mm stanchion tubes, shielding your chrome upper tubes from premature wear while protecting your front brake rotors from catastrophic oil saturation on the road.Product Specifications & Engineering Parameters:
