Since june I have blown out the top headset bearing twice! The first headset was a sealed headset, not sure of the brand, and the second headset, which I have only had for a month is a kink. Not that it really matters, integrated headset, ody director forks, elementary stem, everything is well maintained and checked to be tight everytime I ride. I am about 220 and ride pretty hard, is this something that I can expect or...as several people already suggested to me, will an FSA headset fix my problem??
