Part 85489a

Part 85489a is the large, blind train wheel with a TECHNIC cross pin hole in the center and a TECHNIC circle pin hole off center. This is the first time LEGO has introduced a part like this, but similar parts have been available for a while because of molding experts not affiliated with LEGO.
