Niner TA Thread Pitch

[tuscanyswe]

Broke my handle on the through axle on my niner carbon cross a while back with the axle still in the frame.. Bummer but im about to try and get it out.

But once i have succeded what new axle do i need?

Anyone know the thread pitch on these niner bsb bikes? I know its 142x12 but not the threading.

Thanks u all

The folks at Niner are pretty helpful with that kind of thing and have been responsive when I’ve called them in the past. Good to get peace of mind from the source when you can.

I am not a through axle guy, yet. I've been imagining it would be cool to get up new disc brake cross/gravel rig; there's a hell of a lot of choices. I just looked at this Robert axle project. I love it when people really explain things in depth. Are there really this many through axles?! Same size--three different thread pitches?!

The above methods will get you the right answer, but if you like tools, a thread pitch gauge might be fun to have: https://www.mcmaster.com/2071A18/

Is this one of the "quick release handle" designs?
This is what I put together to get one out of a bike that a friend did off the QR end. If you have enough of the rod available thread a pair of nuts on it. That will create a jam nut and you can grip that to unthread the mess.

Yes exactly, a very poor design for this usage
Mine came off but left nothing to screw anything onto? From what i remember its just a whole into the axle where the handle used to be..

Possibly try a threaded bolt in the other end that's a bit oversize, enough to bite into the inside of the TA and turn the entire mess out from the opposite end.

Yeah if its open on the driveside end that might work but my memory is telling me it was just a solid rod on that side tho i havent looked at the bike out of annoyance since i was left holding the handle pictured below as i just felt the air getting sucked out of me when it happened .)

[SpeedyChix]

If that rod is snapped, tap the bit of it you can see or access into the thru-axle. That should let the bit inside the shaft engage. Vice grips to the balance of the end where the handle used to be and back it out.

Another attempt to describe since words aren't as useful as pics. The handle (when locked) is what keeps things pulled inside so the TA can't be turned. With that gone (based on your pic) if you can get the inner bit of rod that's left into the "locked' area inside the TA you'll be able to use the balance as a place to grip and back it out.


Once you get that pos out of the bike, get a DTSwiss or Paragon Machine Works TA. I've got a stack of those OEM ones that have been replaced with "real" TAs. It's one of the first things I'll do to a bike that's sticking around.
