The Tamer pivot plus that we own went out for the second time after 10K miles. The pivot rests on a metal disc with a depressed center (indentation) and after aproximately 5K miles the pivot worked its way out of the "indentation". All we do is take out the spring-mechanism counting the number of turns that it takes, rotate the metal disc 90 degrees, regrease (lots of grease), put it back in, and it is good for another 5K miles. When it finally gives up, we will give the cane crek TB a try....if I can not convince my wife to switch to a carbon frame before that.
