This inner cassette "lube ring" is recommended for use in Icon, Seraph, Triton chassis
in conjunction with rear cassettes. This lube ring fits PRC "lubable"/larger OD
rear bearings. The purpose of this inner ring is to allow the fit and tolerance of the
rear bearing within the rear bearing cassette to be more precise than ever before.
*White lithium grease is recommended to be used between the bearing race
and lube ring to prolong the life of the ring*
