Enduro HyGlide Fork Seal Kit For RockShox Forks – 35mm. Service your suspension fork with the Enduro HyGlide Fork Seal Kit. HyGlide seals utilize the material and design advantages of our two-part seals (Polyurethane wipers and Moly-Disulphide-infused oil seals) and combine them into a single wiper/oil seal. This unique design joins the oil seal and wiper into a single unit creating a sealing system that eliminates one of the sealing lips and decreases seal friction or stiction by 25%. The cold-fused integrated seal design also features a large oil cavity between the two sealing lips to prevent contamination and further ease forks movement.
