Velodrome Shop ISIS Bottom Bracket Tool for fitting and removing ISIS Bottom Brackets.

ISIS Drive, the International Splined Interface Standard, is an open standard splined specification for the interface between a bicycle crankset and the bottom bracket spindle.

It was created by King Cycle Group, Truvativ, and Race Face in response to the proprietary Shimano Octalink splined bottom bracket standard. Because the Shimano splined interface is covered by patents, the ISIS Group created the standard and put it in the public domain so that other companies could make interoperable components.

As the standards are separate, parts made for one are incompatible with those made from the other; an Octalink-standard bottom bracket (8 spline) cannot connect to an ISIS crankset (10 spline) and vice versa.

Can also be used on SRAM Powerspline Systems.
