Hm, but they are using a different headset though:
• Material 52100 bearing steel
• Preload aluminum/steel 25g
• Upper bearings sealed 28-ball retainer
• Lower bearings sealed 34-ball max
Mine is:
• Material: 440c stainless steel lower
• Preload aluminum/steel 25g
• Upper bearings sealed 34-ball max
• Lower bearings sealed 34-ball max
Since mine has more balls for the upper bearing and different steel for the material, I hope I wont experiene the same fatigue? In my mind, the DH and freeride headsets will be stiffer, due to more balls (same amount on upper and lower) and different material might also be better. (ps. Since they have black and orange, I see they use the all mountain, not the dh headset). If they had black and not orange on top, they would be using either the freeride or the XC.
