| 1246.1 | or... move to Kansas? | SHALOT::ELLIS | John Lee Ellis - assembly required | Thu Jul 13 1989 09:37 | 14 |
| Chip,
This is a relatively well documented (also in this notes conference)
problem, or phenomenon. The first little "index detent" does tend
to seat itself in the straight-forward position, from my experience
at least. People have found Campy headsets to be especially prone
to this. Ed Fisher has with his C Record. I did with my Super Record.
That being so, 'til it really causes aggravation or a safety problem
(which it can!) I say live with it. If you have a small frame size,
people advise pin-bearing headsets such as the Stronglight. The
smaller the frame, the more shock to the headset.

| 1246.2 | What I was told | CIMAMT::CHINNASWAMY | The Mindless Cannibal | Thu Jul 13 1989 09:47 | 9 |
| Do you ride your bike on a wind trainer that connects to the front
fork? I was told that constant use on a wind trainer can cause this
to happen. I guess it happens from wiggling the handlebars slightly
during use which will form a groove in the headset. I beleive it
can also be caused by an overly tight bearing adjustment. Just
what I heard from the bike shop.

| This can also be caused by the way the bikes are shipped from the
factory. the headsets are torqued down so that the fork will not turn
which creates little dents in the bearing races. A couple of weeks ago
I was in a bike shop when the mechanic opened up a new fuji. Not only
did the headset feel like it had indexed steering but when he opened it
up there was no grease in the bearings and a bearing was missing from
the ring.

| 1246.4 | try some preventive steps: | TOOK::R_WOODBURY | why silver bullets!?!? ... | Fri Jul 14 1989 17:59 | 9 |
| Before it gets worse, take it apart. Remove both races from the
frame, and rotating them a little, say 45 to 90 degrees. Put them back
in carefully with either a special tool if you have it or by tapping
them with a soft metal bar (brass, etc.) and hammer or mallet,
alternating sides. Clean out the old grease, repack it, make sure it's
adjusted perfectly. Check it again every 50 miles for the next 200
miles.
Good luck!

| 1246.5 | THANKS | WMOIS::C_GIROUARD | | Mon Jul 17 1989 09:27 | 4 |
| Thanks for the help. I adjusted the headset, backed of the tightness
just a tad and all is well.

| 1246.6 | This happened once. | NOVA::FISHER | Rdb/VMS Dinosaur | Tue Jul 18 1989 12:59 | 9 |
| There is another way to get an indexed headset, I had this happen once.
The bike had been unused for about a year and I discovered that the
headset was severely indexed. Upon disassembly we discovered that the
grease had dried so that there were precise positions for the bearings.
After cleaning it and replacing the grease it was fine.
Of course, I don't think that would ever happen to anyone else.

| RE: .-1 (grease congealing in headset)
... in your case not for lack of riding! just because of your
ever-growing bike collection... guess it's hard to get around to
riding them all. :-)
