The Clevite 77 design incorporates the strength of a copper-lead layer on a precision steel back and finally, a precision electroplated thin overlay of babbitt material only .0005' - .0008' thick.
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.
Racer can pick upper or lower and coated or non-coated from the drop down menu.
