Am wondering if anyone is having any problems out there with their integrated headsets. Should be long enough for some folks to have some miles on them and I was wondering how they are holding up? Thanks.

My first int. headset, CaneCreek, had an interference problem(A lot of them did) and it was replaced under warranty. The only other issue I have seen is a couple of Pinarellos that use a proprietary bearing presse directly into the headtube. On these if you ride lots of miles in all weather and hang your bike by the rear wheel, the bearings will seize from water contamination. This might happen with any headset under similar conditions.

My Pinarello and my buddy's both have a bad lower integrated headset bearing. I'm not sure what causes it, and I have no idea how to replace it. They are both about 2 years old.

First, order some new bearings(Just to make sure you can get them) from pinarello. Or you may be able to get the # off the bearing and get it from a supplier.
Now take off the stem, wheel and brake. Using a block of wood and a hammer (Or a rubber mallet) tap the fork out of the lower bearing. (Yours may be different, but the ones I have worked on have the fork pressed right into the bearing)
Remove the bearing.I like to use the park bearing removal tool, looks like a pipe with the end cut and flared. It WILL screw up the bearing as it presses into the seal area, but it helps keep it square when knocking it out. You can use a long punch and carefully work your way around the bearing to tap it out more or less square.
Tap the new bearing into the frame. Use a big socket that hits the outer edge of the bearing. If you dont have a socket big enough try a piece of pvc or metal pipe from the hardware store. NOTE: Test your knocker to make sure it fits freely into the frame, so you dont bang the lip of the headtube up while tapping the bearing in.
Now the fun part. DISCLAIMER:I don't know if this is the right way to do this, but I could not come up with a better way). Take a eight inch piece of two by four and carve it until it fits perfectly into the crown of the fork(It will fit in the area the wheel goes) Now have someone hold the frame upside down, slip the fork into the headtube and carefully tap it into the bearing using the block.
Reinstall the loose parts and adjust.
Or, you can take it to your pinarello dealer and go "Hey, I paid three grand for this thing and the bearing is screwed up. Please fix it." :D

my moab came with an integrated headset. lower stack and also no need to press any cups. i had a sketchy feeling about it at first, but after a couple hundred miles it's held up just fine without any problems.
