Mondraker foxy carbon R bolt removal has hit a snag, help needed

[ishaw]

The thing is, I'm not sure it should be how it is on the bike currently. It should just be a bolt that screws into the chip with spacers.

Part wise, ideally I'd only need the bolt tbh as long as I can get the ones fitted out, as once out, should be able to screw bolt into the chip rather than whatever has gone in to create what's there now. The next inside the bolt is impossible to use, it requires such a tiny Allen key you can't put any force through it.

But that is exactly what you've got; a flanged aluminium bolt with a hex on either end to give options for (dis)assembly, and the chip. Is the hex on the flanged side of the bolt also too rounded to use, or can you try that? It looks exactly like every other Mondraker I've seen from that generation.

That's strange as it doesn't look the same as the exploded diagram. If I can get the bolts out maybe other options will become evident as I don't need the full kit and it is expensive.

Much words of wisdom

Thankfully mine aren't sheared but useful info. Hopefully the kits I've got to aid removal will do the job.

Indeed noted they weren’t sheared but I’ve done same with rounded Allen heads - initially I did not whack the bolt extractors and had poor results - but using good ones, drilling a perfectly central hole and selecting the right size, then whacking it to get it to bite seems the right thing to do.

I should have said also that also I have soaked them in PlusGas, then shocked them, then used a flat head screw driver head hammered into the head, then extracted with an impact driver. Brutal but works.

And then wait for method 3 in this….

Stripped Allen removal tools

Success. I managed to get the bolts out using the laser tool recommended. It didn't work from the outside hex, that just span pretty easily so clearly the previous owner really did a job on that.

On the other end, worked a charm.

Don't think I'll be able to re-use them and a full link kit is £85 and I really only need the two bolts.

I'd like to think I can find some alternative bolts rather than buy a full kit.

I'll measure the vitals on the ones that came out and hopefully I can source some.

Aside from the trek option mentioned, anyone else found a good source of suspension pivot bolts?

According to the parts diagram, it's described as a pivot axle.

M10x15.

What does that translate to in English

Measure the pitch of the threads if you can. To prevent play in the bearing I think the OD of the shank is going to be pretty critical (i.e don't use a full threaded standard steel bolt as it'll be undersized and allow play). If you don't have a pitch guage then measure the end of the bolt to the start of the threads and divide by the number of threads. It'll either come out as 1.0 or 1.25. Once you've confirmed that then you can have a look at those Trek bolts as they're M10 and likely the same pitch, and available in different lengths to suit.
