THIS 44 TOOTH VINTAGE SPROCKET WAS NEVER USED ON A BIKE AND IS IN NEW CONDITION. THE CHAINRING IS 44 TOOTH. THE SPIDER IS 110 BCD SUGINO DECALED AND WILL LOOK GREAT ON ANY VINTAGE OR OLD SCHOOL BMX FROM THE 1980S AND MANY OTHER YEAR BIKES. THIS SPROCKET IS LIGHT WEIGHT ALUMINUM AND THE SPIDER HAS A TEXTURE IN THE STEEL SIMILAR TO GRAINS IN THE STEEL OF THE 1980'S PRO NECK STEMS. THIS WILL WORK GREAT WITH THE 3 PIECE OR 1 PIECE CRANKS. THIS COME COMPLETE SET WITH ORIGINAL SPIDER BOLTS. THE CHAINRING SPIDER AND BOLTS ARE NOS FOUND IN A WAREHOUSE OF PARTS. LOOK UP TONS OF OTHER BMX PARTS LISTED IN MY STORE AND MORE TO BE LISTED. THANK YOU.
