ENVE builds some of the finest carbon wheels in cycling, and the SES hub system deserves bearings that match. Our kit replaces all hub bearings with Grade 3 silicon nitride ceramic hybrids — DLC-coated races, low-contact seals, and ABEC-5 tolerances. The reduced rolling resistance pairs with ENVE's wide-profile aero design to deliver watts back to you. Compatible with ENVE SES and Foundation hub platforms.
