Replacing the stock bearings with sealed ceramic units delivers measurably lower rolling resistance through the pedal stroke. For road riders chasing efficiency on a wide-shell frame, it is a small upgrade that pays back across every long ride.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eConstruction \u0026amp; Materials\u003c\/strong\u003e\u003cbr\u003e\nEach cup is CNC machined from solid aluminium to the precision tolerances the BB386EVO standard demands, then paired with a sealed C-Bear ceramic bearing. The ceramic running surfaces are harder and smoother than steel, which means lower rolling friction and a longer service interval than a typical alloy bottom bracket.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003cbr\u003e\nFits any BB386EVO press-fit frameset - 46mm shell diameter, 86.5mm shell width.
