Exactly as listed, diameters and length are both correct. Well finished and strong enough for general use. Beware of others that say they're 180mm but are only 150mm. Two thumbs up.

Bij mij bleek het niet te passen in combinatie met een Ahead stuurpen, beide hadden dezelfde maat dus of de stuurpen of deze adapter hebben fouten.
