Miche's cartridge bottom bracket with sealed bearings has a 107 mm. spindle with ISO tapers. The cups are without flanges, permitting adjustment of chainline (within a limited range). The splines are the same dimensions as used by Campagnolo, so tools for installing and removing Campy bottom brackets will also work for Miche.
N.B. - Deviating from the standard chainline on a track bike can have serious ( potentially dangerous) repercussions. Please consult a skilled mechanic if you are unclear on the ramifications of this procedure.
