Or, alternately, take off the Campy crank, put it back in its box with weirdo instructions (1. Rectify the thread of the bottom bracket shell by means of the Campagnolo tool 721, in order to remove any presence of varnish, and to assure a perfect concentricity between the two threads... 3. Do always lubricate the balls housing, with the special Campagnolo grease... and block the lockring by means of the Campagnolo tools 712, 712/1, 713), and sell it on ebay to finance the purchase of a track wheel for my girlfriend = forced fixed gear ("honey, where are the brakes?")
