CAMPAGNOLO CENTAUR - 10 SPEED ULTRA DRIVE - ITALY - 53/39 - 172.5MM - CRANK? - READ PLEASE! PREOWNED - SEE PHOTOS: SOME MARKS, SCRATCHES, IMPERFECTIONS, PEDAL 'MAY' HAVE CRACKS (SOLD AS.IS - NO VALUE), CLEANING SUGGESTED. ITEM DOES NOT APPEAR TO HAVE BEEN USED MUCH, IF AT ALL. PLEASE LOOK CLOSELY AT PHOTOS, AS MY EYESIGHT IS IMPAIRED. I KNOW NOTHING ABOUT THIS ITEM, SO IT'S UP TO 'YOU' TO DETERMINE ITS FUNCTION AND IF THIS ITEM IS FOR YOU. SAID ITEM MAY HAVE ANOTHER PIECE/PIECES, HOWEVER, THIS WAS ALL THAT WAS FOUND - NOTHING ELSE OTHER THAN WHAT IS IN PHOTOS IS INCLUDED. I 'THINK' THIS IS A CRANK, BUT I'M NOT CERTAIN - PLEASE VERIFY. I'M SIZING DOWN...THIS CAMPAGNOLO ITEM IS LOOKING FOR A NEW, SPORTY BIKE!! :) USPS MAIL.
