How was the bearing replaced? It's *very* easy to damage the
bearing during the installation process, or simply install
it slightly out-of-plane. Either one causes trouble. I know;
my first installation didn't go so well!

Shouldn't be a problem, but you want to make sure you don't
contaminate the bearing with it.

Yikes, the way it's put in I doubt you could remove it
without potentially doing some serious damage to the frame.
Don't think I'd go there.

Not sure how this would work, but it would be a neat trick.
Keep in mind that it would require a new fork as well, since
the reason for the larger lower bearing is to accommodate
the special steer tube the older 5900s have, which is larger
at the bottom and smaller at the top.

headsets?
Nah, none whatsoever! :>😉
PS: It's time to replace my bearings again; with what I put
my poor bike through, they last about a year and a
half. Yes, I'll admit it, a Chris King headset, as
allowed by the newer 5900 & Madone designs, would be a
nice thing to have. That'll have to wait a while
though, as I rather like my 5900, and tend to keep my
bikes for a number of years.
