Santa Cruz Bronson V4 suspension bearing kit. 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 treatement. The other 4 bearings are for the lower linkage and are "greaseable" so are shielded on one side and open on the other for use of a grease gun via the "Zerk" fittings on the linkage.
