I've got a fox 36 talas RC2 from year 2006 and it's missing one of those black threaded inserts that pinches the front axle :

the part is M5 threaded, and approx. 28mm x 8.05mm

How is this called and where can I find a replacement? Is there an archive of parts numbers like for cars somewhere? I've only managed to find year 2015+ square pinch inserts so far like this one :

Thanks in advance

  • If the bolts used are M5 (test against the one you have), a barrel-shaped seatpost clamp nut might work. Maybe your local bike shop has one lying around?

  • Hello that was a good idea, i tried with my own seatpost nuts and they are slightly too big for the hole in the fork. is diameter of that nut standard?

    It looks like a fairly straightforward part to make. If you've got an example, its even easier. The critical measurements are the hole size/thread, distance apart, and that the whole thing fits into the space in the fork

    I would love to make it if I knew how and had the proper tools, I am no machinist.

    @JohnDoe: Not all seatpost nuts have the same diameter. I'd check with a (patient) and dedicated LBS mechanic or maybe a local repair commune. Most of them have part-bin-treasure troves. And if the diameter is only very slightly too big (0.1mm) careful reaming of paint inside the hole might suffice.

The one you have pictured is called a "pinch bar" or an "axle pinch bar"

I was unable to find a vendor who sells a 2006 version like yours. The one on your fork appears to be rounded. The newer ones appear to be square - like the last picture in your post. Here is a link to a vendor with a 2015 version (not a recommendation).

Here is a link to a 2005 manual for your fork. Sadly it does not list the pinch bolt anywhere but it has other information that may help.

  • Is it harmful to ride without the axle properly pinched?

    @John Doe, Yes, your front wheel may fall out. Standard M5 nuts might actually fit, but I would not personally feel safe riding such a hack.

Thanks for your answers. Local fox service shop told me the reference is 229-19-030 and they call it "cross-pin axle", as can be seen on this dealer :

I was also able to find nuts with 8mm OD that could fit on a well known marketplace enter image description here

Fox says to apply very little torque on that part and that it is just to prevent the axle from going loose so it should be fine.
