Wheels Manufacturing Bottom Bracket (Red) (PF30) (30mm Spindle) (Angular Contact Bea... - PF30-BB-AC, Wheels Manufacturing's original PF30 "press fit" bottom bracket is a significant upgrade to any OEM PF30 bottom bracket. Two machined aluminum cups offer increased durability and bearing life, while keeping a simple press together method for installation and maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement. Direct replacement for SRAM, FSA, and other PressFit 30 bottom brackets. Enduro Angular Contact 6806 Bearings: In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear. Grade 10 Chromium Steel Balls: High precision balls are within 10/1,000,000? round, twice as round as the industry standard, at its highest level. Filled with Rheolube special synthetic grease formulated in the USA, the balls are micro-coated with long lasting protection from friction. "LLB" dual lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.
