Does the Ultegra 10 spd cassette lockring not make that clicking sound when you tighten it, like the 105 does (and other Shimano cassettes I've encountered)? When I tighten the ultegra one, it is smooth. The only reason I ask is since the lockring and cassette came loose during a ride. Although I've since tightened the hell out of it, I wonder if it might come loose again because it doesn't have the clicking teeth others do. Perhaps a manufacturer's defect?
