Norco Shinobi 29er suspension bearing kit for frames manufactured starting in 2012 through 2013. Includes 10 pcs Enduro MAX (full complement) sealed cartridge bearings, 8 pcs have black oxide anti-corrosion bearing race treatment. 2 pcs have special extended races. NOTE: A change was made without a distinct cutoff time. Some frames use the special bearings with the extended inner races. Others use "698" bearings without the extension. BOTH types are included in the kit so you are covered.
