This custom-designed bearing allows 30mm cranks to be fitted directly into BB86/92 framesets using flanged bearings that press directly into the bottom bracket shell, providing a clean solution in tight spaces. These Ceramic-Hybrid bearings feature 52100 high-carbon chromium steel races paired with Grade 5 Silicon-Nitride (Si₃N₄) ceramic balls, packed with 90% high-pressure, waterproof grease. The ceramic balls reduce steel-on-steel contact, roll smoother, minimize wear, and extend bearing life.
This bearing is specifically designed for BB86/92 framesets and cranksets with 30mm spindles (BB386 & BB30). For a more robust option in the same BB/crankset configuration, consider Enduro’s double-row bearings in this size (DRF041).
