Honestly couldn’t tell you mate ~ maybe someone else on the forum knows? They fit square taper but no idea about JIS/ISO spec. Im guessing as white ind. is a offshoot of sugino it would be JIS?
WI isn't an off shoot of Sugino. These are Sugino cranks with the WI logo stamped on them.....used under license iirc . They came as standard on some late 90s Marins but are still very nice cranks.
Do you know if they fit JIS or ISO square taper bottom brackets?
