Sealed bearing integrated headset question(3 posts)

Sealed bearing integrated headset questionSid the sloth

I'm on the verge of purchasing my first road bike with an integrated headset. After reading the Chris King article that's been floating around here, I decided to learn a little more about integrated headsets, so I took a trip to a bike shop, and looked at a Specialized S-Works road bike frame which utilized an integrated sealed bearing headset. This headset used sealed bearings, which according to the guy at the bike shop, merely sat inside the head tube. Since they were sealed, they only made a fixed contact with the frame, and didn't rotate on any part of the head tube, (i.e. the bearings didn't rub against the head tube cups). After seeing this, I don't understand how integrated headsets can wear out a frame this way. Are there integrated headsets that use the head tube as bearing cups- where the moving bearings have moving contact with the frame? I guess that would be considered a non-sealed bearing integrated headset. Seems like an integrated sealed headset would be the way to go. Lastly, are all integrated sealed headsets the same for the most part?

Uses cups pressed into the headtube that the sealed bearings sit in.

That's the problem.

Some guys have been stung in the past with difficulty or even inability to get replacement parts for similar propriatery components like headsets and bottom brackets. I think that's a risk that you take when you want to be on the cutting edge. On the other hand, it's only money and you can always make more. Some guys are willing to take that chance in order to be au curant.
