This press-in solution allows BB30-style cranks to be installed directly into BB86/92 framesets. With the shell’s limited 41mm inner diameter, a specialized design is required to accommodate the 30mm BB spindle. By using flanged double-row bearings pressed directly into the BB shell, contact area is maximized by doubling the number of balls per side, delivering a durable, long-lasting solution in a tight space.
This bottom bracket features flanged, double-row bearings with 440C stainless steel balls and races, providing long life and superior corrosion resistance even in challenging environments. The kit includes seals to protect the bearings from dirt and moisture, as well as a selection of spacers to fine-tune your chainline.
While stainless steel has approximately 20% less load capacity and is slightly softer than Enduro’s standard 52100 chromium steel, it is ideal for wet conditions, frequent bike washing, or exposure to sweat. These bearings also feature LLB-type seals and CRC Marine Grease for additional waterproofing. Enduro backs the quality and durability of these bearings with a three-year anti-corrosion guarantee.
This is one of the many bottom bracket solutions Enduro offers for the wide variety of standards on the market. For a complete overview, refer to the Enduro BB Solutions Chart. Enduro provides options for nearly any configuration, from standard ABEC-3 bearings up to XD-15 Ceramic Hybrid bearings with a lifetime guarantee.
