Santa Cruz Megatower suspension bearing kit for all current Megatower frames (V1 and V1) through 2022. Includes 8 pcs Enduro MAX deep groove radial cartridge bearings. 4 of the bearings are double sealed and have Black Oxide anti-corrosion bearing race treatment. The other 4 lower linkage bearings are shielded on one side and open on the other so that they can be serviced by using a grease gun via "Zerk" fittings on the linkage.
