Not to mention the thread title pretty much said that was pros (plural) problem.

What did the three finishers ahead of him ride?

And the final word on this:

A 'significant impact' was to blame for the broken spoke, says Roval


Chris Wehan, Roval’s category leader, told CyclingTips that not only was an impact the cause of the broken spoke, but the spoke in question was actually a drive-side spoke. However That means it was on the opposite side from the disc rotor, so head would have to travel through the rotor, rotor arms, and then hub shell to get to the spoke heads on the other side.

BF argues about chain lube, tubeless tires, and brakes on the daily. Do you really think there is a final word?

Apparently you think I did, and perhaps don't understand the meaning of explicit.

I'm a USAF trained wrench and troubleshooter on the F-16 for the airframe, hydraulics, pneumatics, engine, etc., and a retired aviation mishap investigator; trained in metallurgy, stippling points, heat and stress fatigue of materials including alloys, ti, carbon, plastics, etc,. which is a fraction of what's involved in investigating major accidents, systems, part, human failures.

I was just killing a moment of boredom when I posted this very interesting story about supposed failure.

Cheers.

So you must have realised the story linked was utter BS then right?

Miles2go

"Utter BS" isn't a finding classification for post investigation findings, and humans are highly inaccurate sources for recounting what actually happened. So in the investigative field we record what is said, interview, but always turn over every stone, and let the evidence tell the story.

...but I'd say Wilco had a bad day, and found a way to make it worse.

So, when Joe Newbie states he can produce 1,000 W for an hour, it can’t be called out as utter BS because “Utter BS” isn’t a “finding classification”?

Are you really under the impression that this puffery is helping your credibility? Fun.

Don't forget waving.

Are you under the impression I care if you continue to attack me? Have at it Hoss.

Koyote

The appeal to authority fallacy is not a good look.

WhyFi

There's a difference between attacking someone and being critical of their actions. Your actions have been ridiculous. You found an article with a meritless accusation and you either tried to give it merit or you made a clumsy attempt to troll. Your actions since have consisted of attempts of face-saving posturing by citing skills, credentials, and procedures that, if actually employed, would have immediately seen the rider's accusation for what it was - unmitigated BS.

WhyFi

Exactly.

Miles2go

Listen self-important judge and jury, find a court that cares about your accusations surrounding my actions and intentions, for which you ultimately know. All the people I wronged in this post are counting on you.

Did Kelderman's disc brakes break his spokes? No, and here's why.

​​​​​​

Can disc brakes overheat spokes?

No. Not only was an impact the cause of the broken spoke, but the spoke in question was actually a drive-side spoke. That means it was on the opposite side from the disc rotor, so heat would have to travel through the rotor, rotor arms, and then hub shell to get to the spoke heads on the other side.

Further: before a spoke could fail under heat stress, the rotor would be “fire-red” and melting both the rotor and the pads, the mineral oil would have long since boiled off, all of which would result in complete brake failure. If that wasn’t warning enough, and should a rider still be upright and somehow still pulling heavy on the brakes, Leven imagines the hub bearings would expand next damaging the hub shell and providing an additional warning of imminent danger.

​​​​

What about the spokes?

Roval uses DT Swiss Aerolite spokes in its new Alpinist II wheelset. The 18/10 stainless steel DT Swiss uses in its Aerolite spokes is known for its heat resistant properties and can withstand temperatures up to 925°C (1,697°F) before it starts degrading.

WhyFi

Now that's comedy - calling someone else "self-important" after tediously citing qualifications that you were clearly unable to demonstrate.

Anywho, I'll take my leave - what's on offer here isn't much and it's clearly circling the drain. Have fun.

My experience is that, when failures occur, end users tend to blame the component, sub-system, or process that they know the least about.

Miles2go

Well, the comedy is you claimed this post was perhaps a weak attempt at trolling, and if true, it was the weak who kept responding to it, making the thread outlast the story itself. That's comedy.

Bah Humbug

What the minions?

I was right. Seems like Groundhog Day.

So you're saying the spoke broke back, and to the left?

Can disc brakes break spokes?

The simple answer is, yes.

Mojo31

Drum brakes. Problems solved.

cxwrench

But not from heat. And as stated in the article highly unlikely even due to spoke tension issues.
