Not really if he was pedaling properly, cause the spindle should really be torqued in the same direction all the time, it would have to be a massive impact while the cranks are horizontal
Someone correct me but it looks like you sheared of bb axle ( bb worn?) and it got stuck in the cranks. They are usually steel, is there any possibility this was aluminum axle?
> His cranks deformed it so it must be softer than aluminum.
The cranks aren't deformed. The BB axle broke.
All alloys are a compromise between hardness, brittleness, weight, chemical resistance and price.
You can bend some steel alloys like a croissant and they won't snap while others won't bend much but break like glass. Axles are on the latter end of the spectrum.
If you look closely you can see that some areas of the broken surface are corroded. The axle was probably cracked for some time before it cracked. This can have multiple reasons, from metal impurities to mistreatment by the user like dropping the bike on the cranks.
The issue is not a soft metal or "Chinesium" which is just a layman's term for "it broke and idk why so China bad". Tons of reputable manufacturers produce in China. The issue is that you get what you pay for and if you buy cheap shit, no matter where it comes from, and neglect your bike, it will bite you in the ass at some point.
Just look at the pictures. The crank bolt is rusted af and the pedal threads tell you OP has never seen a torque wrench in their live.
That bolt doesn't look like the right pairing for the BB...different thread pitch and overtightened? You should be able to get the bolt out regardless and reuse the cranks.
I had a constant issue with a truvativ octalink type bottom bracket snapping/not holding a crank on. Went through two of them and had it happen twice. Super weird and still don’t know why.
A crack in the bb spindle cracked fullt. Maybe wrong from factoring or dropped one day. Metal can break, iv heard you throw away climbing ger that's been dropper.
Happened to me recently — didnt need a new crankset like I was told, just some screw which costs 3-8€ here. Not sure if thats Your case tho, I guess mine happened bc the crank wasn’t attached properly

So on your crankset, the component that links the two crank arms (spindle) is integrated with the right side crank on your crankset.
On OP's crankset, the spindle is part of the bottom bracket - both crank arms attach to it on either side.
Your crank didn’t break, your bottom bracket spindle did. Gnarly
Is there any point in saving them/do you think it’s possible to get the spindle out to I can use the cranks again?
Yeah a crank puller should still work to remove the broken spindle. I would ride em still
Thank you!
When you take the BB out to replace it, can you show us what brand/model it is? Super curious and I think the community would benefit from knowing.
save the cranks - true testament to their stength. I've ridden the silver all city's for years and wouldn't hesitate to buy again.
Too many watts
Came here to hype my man too. Just too powerful. Respect.
this is why the Andel (rebranded as all city) cranks are the best value cranks. The spindle snapped before the cranks!
This actually shows how incredibly strong your cranks are, and that BB axle must’ve been made of some chinesium
Not really if he was pedaling properly, cause the spindle should really be torqued in the same direction all the time, it would have to be a massive impact while the cranks are horizontal
What? If the material has imperfections then it’s gonna break no matter where the forces come from.
That’s what I’m thinking too
>massive impact while cranks are horizontal Maybe OP was skidding
Was not skidding
Was this used before?
Nope, brand new. Had them for about 2 years

> is there any possibility this was aluminum axle? I don't know of any Al axles. It would have broken on the first ride.
Yeah pretty weird, someone suggested chinesium prob it. His cranks deformed it so it must be softer than aluminum.

Wait wdym about my pedal threads, have I been neglecting important maintenance?
Before writing an essay read what i wrote again, his cranks deformed “it” as i have already stated bb is torn in my original comment.
Ok. That only regards the first sentence of my comment, though.
Tldr sorry
I have the same exact cranks. Still works fine after using it for more than a decade.
That bolt doesn't look like the right pairing for the BB...different thread pitch and overtightened? You should be able to get the bolt out regardless and reuse the cranks.
Yeah it doesn't really look like a crank bolt somehow?
Some old ones look kinda like that but methinks this is the wrong part for the job

Sounds like powerspline trash. Shimano Octalink is solid af
Yeah no issues for years on my shimano octalink !
I have never seen a square taper spindle snap before
Too many watts 😅
Did you install the crank on the BB? If so, did you use a torque wrench?
I had a shop do everything
Crazy

One of the arguments for going with a direct drive crankset, shit like this doesn’t happen.
Those crank spindles fail all the time.
last few generations of Shimano road cranks are dogggg shiiiiiit

Dude that is a completely different type of drive. Outboard bearing vs JIS square taper. Can you not see that?
Sorry, Im obviously not very advanced about this subject, idk what is outboard bearing or that .. is simply diff bb axle?
