This press-in solution allows you to fit your SRAM DUB cranks directly into your BB86/92 frameset.
It is a tight fit due to the limiting factor of just 41mm inner diameter of the BB86/92 bottom bracket shell, requiring a special solution to accommodate a 29mm BB spindle. By utilizing flanged double-row bearings that press directly into the BB shell, the design maximizes contact area by doubling the number of balls per side to provide a long-lasting solution in a tight space.
This complete bottom bracket features flanged, double-row bearings with 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. Included with the kit are seals to protect the bearings from the elements and a selection of spacers to allow you to precisely tune your chainline.
Though stainless steel may have about 20% less load capacity and is slightly softer than standard 52100 chromium steel used in most bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. Enduro Bearings also uses LLB type seals and CRC Marine Grease in these bearings to additionally waterproof against the elements.
Like most bottom brackets, this double-row solution requires precise adjustment to guarantee optimal performance. Some cranksets have pre-load systems already built in, but if yours does not, or if it is made of plastic, this BB kit now includes a machined aluminum pre-load adjuster along with a full complement of BB spacers to ensure precise chainline adjustment.
