If you have a 2x cinch spider you could by the 104 BCD version...I paid like 50 or 60 LOL. Mine is center cinch so I still cant get this deal if I needed one for some reason that is more

Fact remains.... you are making a lot of assumptions here without knowing the details and stating them as facts.So, was just the immense power of that one stroke generated by you leg that did it? Do tell...
Nope,when asked to stop I stop. Nothing to see here.
Ere, I was talking about mine. Didnt we have the same issue? Where our incredible power was too much for the chainring to handle?Stress fracture? You act as if you were there. Please
Similar.... but my chainring didn't crack... and it wasn't threaded either.Ere, I was talking about mine. Didnt we have the same issue? Where our incredible power was too much for the chainring to handle?
For my experience breaking one, yes. I weigh 230lbs and the ring wasnt threaded enough. The part it was threaded into was about 1mm thick aluminum. If it were threaded into the actual body of the chainring as it is now, it would not have broken...presumably.So, was just the immense power of that one stroke generated by you leg that did it?

Ah, so different circumstances. Thread failure on the jacket? Or did the jackets actually snap/crack?Similar.... but my chainring didn't crack... and it wasn't threaded either.
Sorry, not at liberty to speak about this issue, I wasn't there so obviously can't comment on tensile strength of aluminum...For my experience breaking one, yes.

Fuck what Paul says. The other issue is how it was machined and any inconsistent thicknesses or fractures, but all 4 snapped on mine. It was curious that the 2 that snapped fully off were at oposite sides and same gor the om2 that were half off. I'm referring to the built in spacer of the chainring.Sorry, not at liberty to speak about this issue, I wasn't there so obviously can't comment on tensile strength of aluminum...

Nothing cracked
Because the bolts were short, it didn't thread into the female part far enough and stripped the thread.
Bolts were useless but chainring was fine.
I think he was assuming we had the same issue...so aluminum chainring being the cause of fuckery.BTW... my bolts were supposedly titanium so no idea what aluminum tensile strength have anything to do with it when the AL chainring was totally fine.
Cause and result was the same but different failure (not sure if you can call it failure if it was user error) ptsI think he was assuming we had the same issue...so aluminum chainring being the cause of fuckery.

My chainring had no threadsTensile strength of aluminum (9,000psi to 79,000psi) and titanium (25,000psi to 230,000psi) partially overlap, with the best aerospace aluminum alloys being stronger than the lowest grade titanium alloys. So if your chain ring aluminum alloy was 'better' than the titanium used for the bolts the bolts would have given way. So the chainring threads did not get any damage, not even at the beginning of the thread?
...dead horse here
