Hello
does anyone know what the difference is between the versions with the "4 star" and the "5 star" in the middle? Only optics? Both versions are available for 140mm and 160mm...
140/160mm always have only four struts. 180/203mm have five struts. Sometimes you can't rely on pictures at Galaxus. If there is a difference, then the others could have external teeth. However, the manufacturer number listed there also points to internal gearing. The ones here definitely have internal teeth.
Anonymous said it right. Whether 4 or 5 star depends on the size of the disc. You must pay attention to the Shimano designation. This must match your version. This type has centre lock teeth and only fits centre lock hubs.
