The Campagnolo part HB-HY100 (the fulcrum part number is different but the service kit is identical) fit any campagnlo/fulcrum hub from 1999 onward that uses the 17mm oversized alloy axle and the "cup and cone bearings". That is Campagnolo high end wheels Zonda or Racing 3 upwards.
Exception Fulcrum Zero and Campagnolo Bora front wheels with 15mm front hub axles. These use a different set of parts.
You can upgrade wheels or hubs that came with the standard steel cup and cone bearings or USB bearings but if you have the CULT bearings this kit is the proper replacement.
You get bearing hardened cups, ceramic bearings (caged), cones and seals. There tools to remove the press the bearing cups into the hub. If you require these please enquire.
This service kit fits front or rear hub/wheels and the kit contains parts to service one hub/wheel only
The lubrication for these bearing is light oil like sewing machine oil. That simple dont over think it.
