The Enduro Bearings MRF 3041 LLB - Ceramic Hybrid - 30x41/44x11 is a top choice for cyclists looking to fit 30mm cranks into BB86/92 framesets.

The ceramic hybrid construction features 52100 High-Carbon Chromium alloy races and grade 5 Silicon-Nitride Ceramic Balls, filled with 90% high-pressure, waterproof grease. This combination ensures smoother rolling, less wear, and longer life by reducing steel-on-steel contact.
