|   When to replace headsets | Mikegr
Nov 7, 2002 9:29 AM | | Is there any particular time that it is recomended to replace your headset. I've had my (low end) head set on my frame for about 3 years and I'm swapping my components over to a new frame. I'm wondering if I should do a swap or just leave everything as is. I have not had any issues with my current set-up. Is there a way to tell when it needs replacing or is it one of those replace after X miles parts? |

I'm a pretty big guy (225-240), and I ride a lot offroad over Sierra rocks and fire roads. If it starts feeling notchy, I rebuild, but that's only happened a couple of times.
In your case, since you're building a new bike, I think I'd upgrade to a medium-decent HS. But it's probably no big deal if you don't. |

To check do this - pick up the front of the bike and turn the bars a couple of degrees from straight ahead. If the headset centers itself to the straight ahead position when you let go then it's indexed and in need of replacement.
Also if it's rough then it's probably worn out. When you're switching over just check it out. If it's smooth and index free then you're good to go. |
| Headsets......agree and disagree... | Cashish
Nov 7, 2002 4:54 PM | | Mike T - I agree that an "indexed" HS is a sure sign to replace, just disagree with the "pick up the front of the bike and turn the bars a couple of degrees from straight ahead. If the headset centers itself to the straight ahead position when you let go then it's indexed and in need of replacement" - could be "misleading", as right/left brake/shifter cable housings, in some cases, kinda work against each other slightly to return wheel to center...if HS is indexed, one would feel it just by lifting front wheel and rotating bars back and forth...if it's "notchy" or rough, it needs overhaul/replacement...just 'cause it kinda "self-centers" doesn't necessarily mean it's "indexed".....not to discount your advice, just to augment it :) |
| Headset could feel "notchy" if it's too tight. | third day
Nov 8, 2002 9:36 AM | | If it feels "notchy" it could just be too tight. Take it apart and look at the bearings and races. If any of them look pitted or worn, replace them. If they don't look worn, and if you are able to adjust the headset so that it feels OK, just keep using it. |

When someone is really hard up, using dressing stones on the races (or something more elaborate to smoothly grind), around and around, to grind out the dimples, and return the headset to some serviceability, but don't expect a new smooth headset out of that. |
