Press-In, Flanged, Double-Row, Black-Oxide treated Bottom Bracket solution for BB86/92 framesets.This press-in solution allows you to fit your BB30-style cranks directly into your BB86/92 frameset. It's a tight fit with the limiting factor of just 41mm inner diameter of the BB86/92 bottom bracket shell and it requires a special solution to accommodate for a 29mm or 30mm BB spindle. By utilizing flanged double-row bearings that press directly into the BB shell, we are able to maximize 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 anti-corrosion Black Oxide/Magnetite treated, 52100 High-Carbon Chromium alloy races paired with grade 10 Balls. Black Oxide coating provides an extra level of corrosion resistance and extended worry free performance. Included with the kit are seals to protect the bearings from the elements and selection of spacers to allow you to precisely tune your chain-line.This is just one of the huge range of solutions that Enduro makes for the wide range of bottom bracket standards on the market today. Enduro offers a solution for just about any configuration at multiple price/performance levels, ranging from standard ABEC-3, up to XD-15 Ceramic Hybrid bearings featuring a lifetime guarantee.
