kogel bearing bb86 bb92
BB86 is the road standard: 86.5mm width, 41mm inner diameter.
BB92 is the mountain bike standard: 92 or 89.5mm width, 41mm inner diameter.
The bottom brackets between these two options are the same but Kogel Bearings specs the 'BB86' bottom brackets with Road seals, and 'BB92' bottom brackets with Cross seals.
It is perfectly OK to install a BB92 bottom bracket on a road or gravel bike for extra protection.
