Headset replacement - DIY?
« on: February 04, 2014, 12:53:15 PM »
My headset is trashed. Due to a combination of misadjustment and repeated pothole poundings it has a severe detent in the straight-ahead position. Is this something I can replace myself? I've seen references to "special tools" etc but am wondering if a reasonably handy guy can do without.

probably. on my Foil if I pull the fork out the bearing on the bottom falls out, and the top I can pull out with my fingers. They are allegedly "press fit", but in reality they just sit in the frame and the stem/steerer/fork hold them in place.

I've replaced several of them.  Sometimes there is a pressed-in cup which holds the bearings, but the bearings themselves just slip in. 

If your replacement headset comes with a fork crown race, see if the existing one will work, otherwise you need to figure out how to remove the old one and then press in the new one (I use a PVC pipe and end cap with a hole drilled in it, and pound away with the fork)

If it is an integrated headset (most modern "factory" bikes) then it's should just be a drop in bearing. If it's a traditional style headset then you need to press the cups in. Internal, iirc is like the traditional in that it needs to be pressed in but you can't actually see the cups. I could be wrong on that one.


I actually have a headset press but I use it for my bottom bracket since my headset is integrated.

I use a threaded rod, 2 nuts and 2 big washers as a headset press and a bb press.

Thanks for the tips guys. Sounds like I can do this myself.

Ditto. I added a couple of brass couplers that had a decreasing outside diameter that helped seat the cups straight.

I found that the washers tended to straighten out as pressure came onto them, but your setup sounds good too.


I figured the park tools had flat surfaces... so far so good!

Couldn't get the bottom part out on my trek last summer, ended up bringing it at the shop. So consider the fact that it may be pretty tight or hard to remove.
Challenge it because it is unreachable.
