So, not one to knee-jerk at things without seeking professional help, I've read on Wikipedia that integrated headsets like on my GT Tachyon 3.0 eventually damage the frame when they wear. Of course, a little googling tells me, no, it's physically impossible to change out an Integrated headset for a regular cup headset, because bits of the frame are wrong and won't accept it.

So, great, now what? Do I assume that eventually my frame will die (probably in 10 years, though, so who really cares right now?) and make note never to buy something with an integrated headset again?

Thoughts and suggestions.

I fail to see how an integrated headset can wear the frame, they're cartridge bearings and all the moving parts are internal. OK, maybe there'll be a tiny bit of wear to the surface where the cartridges contact the inside of the headtube, if you replace them enough times, but standard headsets do that as well...

not an issue unless you ride with loose headsets

As the others have posted there is, or should be, zero movement between the headset bearings and the frame, hence zero wear. The only way they can become a problem is if a bearing seizes and then turns in the head tube, but this is something you should be able to feel and correct.

Don't sweat it, your headset seats in the frame will outlast the headset, frame and probably you.

If the frame is aluminum, with the head tube machined to match the 45 degree bearing outer race, it is certainly possible to damage the frame if the bike is ridden extensively with the headset bearings adjusted too loose. That's why Park Tool makes a cutting tool to recut the bearing seats in the frame. Cases of extreme damage that aren't repairable are rare. Much of the literature that predicted short-lived frames came from manufacturers like Chris King, who did not make integrated models, when the warnings were written. Mountain bikes obviously take a more severe beating than a road bike.

A lot of frames have replaceable bearing seats. All LOOK carbon frames have them. A sign of a cheap carbon frame is either using the carbon as a bearing seat, or using a thin aluminum seat that's molded into the carbon and not replaceable. The Cervelo R3 that I owned briefly was made that way.

The best thing about the internet is that anybody can look up almost anything with very little effort.
The worst thing about the internet is that anybody can post on it so a lot of the information you get isn't true.

My advice to you is to stay away from political sites.

See I like this answer. Most people rant about how "anyone can edit Wikipedia" and then go pull up the first site they find on Google, completely ignoring that you can pay $8/year for a domain name and stick whatever you want up and other jerks with Ph.D.s and 45 years of experience can't come by and go, "oh, you're wrong," and edit it out from under you.

I bought a 'locking spacer' [QBP] and put it 1st thing above the upper headset.
so fussing with stem and spacers didn't have the fork coming out.
that made a nice improvement with mine..

The bike: Koga a world tour ready trekking bike.



... on modern frames, I like the smooth flow, visually, between fork and frame.
made possible by integrated headsets.
