RBS is proud to offer the racer Tri-Armor coated bearings as an option. Clevite's exclusive Tri-Armor coating, the industry's only moly/graphite treatment. The sophisticated blend, in a low-friction PTFE polymer base, offers extraordinary protection and lubricity. They also have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating.
