BB86 is a relatively new bottom bracket standard in the bicycle industry; a reworking of Shimano's HTII outboard bearing design in which the frame is widened from 68 to 86.5 mm at the bottom bracket. The bearings are now inserted into the frame via an adapter for increased bottom bracket stiffness, and frame manufacturers are free to use wider tubing at the bottom bracket junction.

The KCNC BB86 is a light press fit bottom bracket, and requires no installation tools.
