Grand Cru threadless bottom brackets fit most frames, even those with Swiss threading. And they work on frames with damaged BB shells, even if the existing threading is totally stripped.
Like the other Grand Cru BBs, these have sealed cartridge bearings, so they require no servicing and should have a very long life. Taper is JIS. These BB's won't work on mountain bikes, as their standard width (73mm) is too wide for the shell to expand. They do not work on Italian threaded BB shells because those have a wider ID.
