Pf30a Is A Cannondale-Specific Standard For Their 73mm Wide Bottom Bracket Shells. This Ceramicspeed Kit Makes It Possible To Install Shimano And Other 24mm Diameter Thru-Axle Cranks Into A Cannondale Frame. Ceramicspeed Bearings Come Installed In Two Cups And Are Connected Through The Shell Via A Spacer Tube. There Are Versions With Standard And Coated Bearings. Both Have Super Round Ceramicspeed Balls And Hardened-Steel Races. The Ceramicspeed Coated Have An Additional Attribute: A 3-Micron Thick Metallic Layer Over The Races. This Addition Makes The Races Harder And Smoother, Lowering Drag And Increasing Life. In The Box: - 2 Ceramicspeed Bearings Pressed Into Cups. - 2 Installed Dust Covers. - Spacer Tube. - All Round Grease. - Sticker Sheet. Technology: Maintenance Of Ceramicspeed Bottom Brackets: - We Recommend That You Follow Our Instructions On How To Maintain Your Ceramicspeed Bottom Brackets To Achieve The Lowest Friction And The Best Longevity. - The Unique Pf30a Shell Is 73mm Wide, 46mm Diameter. These Cups And Bearings Adapt The Shell So It Is Compatible With Shimano, Fsa, And Others. - 0.3-.04 Watts Of Frictional Drag Is The “Cost” Of Our Ceramicspeed Standard Bearings. That’S A Reduction In Drag Of 75% Compared To Stock Bottom Brackets. This Is The Result Of Great Design: Hardened-Steel Races Combined With Ceramicspeed Balls That Are 100% Smoother And 15% Harder Than The Ceramic Competition. They Also Last Longer. - The Ceramicspeed Coated Bearings Last Even Longer And Feature Even Lower Drag. Life Increases By 60% And Drag Drops By 50% Compared To Our Ceramicspeed Standard Bearings. - All Round Grease Comes Pre-Installed In The Bearings. It Can Be Replaced For Lower Drag Race Day Grease, Or Higher Durability Long Life Grease, Which Adds A Bit Of Drag But Stays In When Riding Through Messy Conditions.
