Headset

My headset has start getting 'sticky' and making some interesting grinding noises. I'm pretty sure that this is because the bearings are gone (or am I just revealing my ignorance). It's only started in the last few days, but is getting progressively worse.

Thinking about it, it started on Monday, after getting a thorough soaking several times in the last couple of weeks - is it possible some grit (which covers the underside of the frame and my legs after such a wet journey) had got into the bearing, or is it more likely to just be general wear and tear (it's original and the bike's 5+ years old).

I have it booked in for a service on Friday anyway, but was wondering if this was something that could be easily replaced myself if I had the parts (and the aid of the Park Tool website) - nb I don't have any specialist tools (as yet).

Your comments will be greatly appreciated

    It depends on the type and model of headset. Most modern headsets use replaceable cartridge bearings - you can remove the seals to clean them out and repack with grease, but if the balls get corroded or the housings worn, then you simple pop-in a new set. You don't need any specailist tools for this job. However, if you got an older caged or loose-ball headset, a worn headset often requires the replacement of the cups which are pressed into the frame. Often, the lower cup becomes pitted or notchy, making is feel rough or 'indexed' and therefore needing replaced. To minimise the risk of damage, this is best done using the correct tools - using the wrong tools/techniques without the right knowledge could permanently damage the frame, so best avoided for a beginner. First step is to determine the make/model/type of headset and we can probably advise on your best options.

    Thanks Monty,

    The bike's a 2003 Marin San Anselmo (was off on my estimate of age) - on my limited knowledge and brief inspection it looks like an A-Headset, but it does not state this as other A-Headsets do (might it be a Marin manufactured item and if so different?).

    I hope this might help with your advice.
  • Mine clicks. Not sure exactly why. I hope its lack of grease which I can easily sort out, but with carbon fibre forks clicks are very unnerving.
