Headset bearing maintenance...C'dale(3 posts)

Headset bearing maintenance...C'dalebent_spoke
Aug 13, 2003 6:51 PM
I was swapping stems & my fork dropped down, exposing bearings on the lower end. I didn't know if they are serviceable, but it looks like i can clean & grease the surface at a minimum. Can anyone step me thru this? The top side bearings I image are pressed in. Is there anything that I can do there?? Thanks in advance!

It depends on which bike you have. If it has the Campagnolo hidden set, then it's indeed fully user serviceable for both top and lower bearing. Check the manuals on the Cannondale and Campagnolo site for specific servicing info.

The sealed bearings unit will pop out from the cup or race. You can wipe off the service and apply a lite coat of grease to protect against rust, and clean inside the tube. if they are sealed, I would just replace them if you think they are worn. If, when the bike is assembled, they rotate smoothly with no grinding noise, then leave them alone. They should last for many years. The non-sealed bearings are easy to sevice, clean and re-grease.

Make sure you put the unit in the same way it came out, and you check the headset for looseness after assembling.
