Who is using Akhlut's surfrodz axles? (Axle issues)

If your axles were bent, the cone would be the other way around.

Cone? I’m dum, are you speaking of the angle of the wheels? If the axles bend, I’d expect it to be angled like it is here. You might be pointing out the wheels themselves could be coned, which would also be the case.

It’s sitting on the table wheels down charging. The back right is for sure only touching on the inside edge.

I’ll keep an eye on them, was gonna ride it hard today but outside is bad for my health. Doesn’t really have a lot of miles on it yet.

Brain fart. Disregard my comment.
I was looking at the wheel and thought it was wear.

Could one of the problems be that the momentum of the motor directly causes torsion on the wheel axle instead of the hanger? This seems also be the case with direct drives and when hence them running 12-14mm. The motor is basically on a lever like that and these forces can become quite big. Basically moment=force * levering distance.

Plus on one side the mount is actually putting force on the thread the wrong way

Edit: i think @bwahl602 was ahead of me :stuck_out_tongue:

I think the index rings were supposed to help eliminate this force. However, with the experience most have had with needing to shim the index rings, I’m wondering how effective they really are at doing that.

This is part of the reason I used dual crossbars on my motor mounts.

Ok update time. I took the other axle out. This one was cracking too. If you own a set you should check.

Wow, that’s crazy. You can see the crack! Was the axle bent as well like @Saturn_Corp?

@longhairedboy think this should get escalated over to recall section?

This suckssss to see.

Couldn’t see any bend in mine.

Yeah definitely if you own a set, take them apart and check each one especially @Saturn_Corp. That bent one didn’t look too healthy. I just don’t want someone getting fucked up is all.

Bumped it over to Product Warnings category. Seems like a good place for it. Thanks for the heads up.

Just checked the front ones and they seemed fine. No visible cracking on these.

Went to check the ā€œmore bentā€ axle today. Have trouble getting it out of the hanger. Super difficult to rotate out, and at this point it’s just rotating and rotating and won’t come out the rest of the way. Might have fucked the insert when switching from 5mm to 2 mm spacers and cranked it in.

Wd-40 helped a little with making it rotate easier but no dice getting it the rest of the way. I wouldn’t think the axle is still threaded into the insert but it could be since it’s not coming out.

No sign of cracking but not sure if it’s bent yet. I keep thinking yes, and no. I need to completely remove it.

Oh no :worried: Are you now 1 build short?

Yah I only have the MTB left for now. Trying to decide if I continue building out the Flux I have as I want to, but don’t need it.

Almost certain this is both material and design flaw

That corner is way too sharp, even a 0.5 mm fillet do wonders to reduce stress concentration and thus fatigue

Dang man. So sorry to hear that. Is it worth applying some heat to the hanger?

I torched it a little. I will give it another shot tomorrow.

Axle: 1

At least I did something productive today; this wasn’t it.

If you have a drill press and a tap kit you can drill it and then tap it then put some long cure 2 part epoxy in it and then a bolt. Come back tomorrow and use a wrench to remove it.

That’s assuming the helicoil isn’t shredded. I’d that’s the case you might scar up the inside so much that you cant put a new axle in it.

That being said, I have 2 sets of Matt’s axles with 100s and 100s of miles and have had zero issues.

I suspect theres a burr or something on the inside. Or debris or corosion. Anti-seize helps this

You need to get pulling pressure as you rotate. Rotate the axle by hand or with a drill while pulling on the axle. You can use lots of things to allow rotation while pulling, but that should do it. If it spins, itll probably come out.
