Head Set has affinity towards the center - is it supposed tosurf
May 15, 2002 7:49 AM
This is a hard one to explain and sounds kinda weird but my wheel/headset wants to stay in the middle --which means the wheel is pointing straight ahead. This causes problems when handling. It seems like it does add some stability when going straight but makes turns unnatural.

Should the wheel turn freely or should it have a slight affinity for the center. it feels like as i hit dead center, it falls into a groove. I really dont know how to explain this but i hope you guys know what im talking about. It's an older bike with a quill stem, so i think that means it's threaded headset???

Can i adjust this, any ideas?
You've got a pitted race.MrCelloBoy

You likely took a good pothole while riding straight ahead once. There's a tiny indent now that can be really aggrivating.
I'm guessing you have a non-aheadset type headset.
You'll need to replace the cups and might as well replace the bearings as well. If you have bearings in metal retainers you might want to replace them with loose bearings that will distribute the stresses over a larger surface.
ever polished races?cyclopathic

disassemble and degrease bearings, coat with valve grinding compound, gradually tight it up and rotate to polish. Then wash, replace bearings, grease, assemble. Works if races weren't damaged too badly, easier and cheaper then replacing headset.
Yep. You've got indexed steering. It's Shimano's latest thing.Ken of Fresno

Na, just kidding. Get a new headset and make sure it's properly adjusted and maintained.
Had the same problem -- your headset is shotGator

Best solution is to buy a new headset and move on. It's only gonna get worse, and it's dangerous.
wait !!!!!...it isnt necessarily shot...ishmael

everyone told me mine was shot..id had it too tight and it was seemingly permanently pitted in the center too but i cleaned it and put it back together and it was fine...and i dont see how it could ever be dangerous no matter how badly it was pitted
its too tightskibert

every time I adjust the stem height on my threaded stem the headset tightens, and it sticks in the middle, just loosen it up a little, then hold the front break and push the bike back and forth, you shouldnt feel and play or you loosened it too much

My headset was doing the same thing, on a bike less than a year old. Took it to the bike shop last week thinking it needed a new headset. The mechanic said the binder bolt was too tight and loosened it a bit, and now it works fine. If I dissembled the headset perhaps the races would be grooved, but it works for now.
