Hello friends, I want to consult you something. Thank you in advance for your answers.

I wonder if the bowl we attach to the headtube or if I explain as follows, is there a possibility that the headtube is Licking or the nest may be broken?

In short, even if it is inserted incorrectly, can the socket break?(licking could be?)


I really want to answer this, but not sure if your question is about an inproperly seated headset cup, or something with the bearings or race... but I feel like whatever the issue is, you have the right tools in that room behind you!



Headset I change it,and unfortunately without tools I change it,and there were peeling in the headtub paint Peeling,You know giant dowhill bikes have bad paint,can nest licking could it be ? Because I don't think the headtube will be a solid spot licking

Stan's is the best IMO. Been using it for as long as its been around.

I am happy with stans on my bike but had to do the front wheel in gorilla tape after I damaged it on a Sunday putting a new tire on.

The original tape stayed on for 4 years and multiple tires.

Gorilla tape, if you don't retape often and can deal with residue when the time comes

There is a hack you can do to make sure there isn't any residue. Put some electrical tape down and stretch it so it's thin and covers the whole rim. Then put the gorilla tape on. When it needs replacing. No mess.

Yeah, but then the adhesion to the rim isn’t great, electrical tape isn’t nearly as sticky as Gorilla.

There's a thread on MTBR with 736 posts (and counting, I'm sure) about rim tapes.

There's no such thing as a dedicated rim tape, they're all just off-the-shelf tapes for other purposes that product managers have found to work well and are selling as rim tape ... at many times the price, but they've done the research for us and it's not a huge expense, so we live with it. Most of us, at any rate. The MTBR folks have experimented with seemingly every tape in the world and the results are there for the reading.

Does anyone know if you can remove a press fit bb with a headset remover?

provided you splay the headset cup removers fins so they either engage the outer or inner race lip and not the seal's face, i think it could work but I've never tried.

I'm sure you could if you're careful and methodical. The diameters of the two tools are quite different.

You must keep in mind that most press fit bb shells are plastic or fiber reinforced plastic. So, they will be easily damaged. Just go slow and be careful.

Your best bet would be to have four or five spots around the circumference of the bb shell where the tool is interacting with the shell. Tap lightly, and move to the next spot and tap. Move around the circle several times, tapping lightly. Slowly the bb should work itself out. Don't try to force it or smash it hard with your 5lb hammer. Light taps.

Another thing to keep in mind is that there will be a plastic spacer/dust cover with a ridge on it, and then a bearing with it's own ridge and if you're tooling on either if these you'll knock them out of the bb shell and the shell will stay stuck in the frame. Not that it's a huge deal but its another thing to keep an eye on. If you knock out the spacer/dust cover it can kinda be a p.i.t.a. to reinstall ESPECIALLY if you've mashed it up with your tool. Just make sure your strikes actually hit the shell and not the spacer or bearing.

Looks like the Fortus wheel is available in 142, 148, and 150mm rear axle spacings. Fitment will depend on what year your Kahuna is.
