You are Donald Trump, doesn't like people of other religions. I claim my £5.

He loves hollow spindles though. They're big and beautiful, apparently, not like the square taper rubbish favoured by those countries that are hoarding Amneric's oil! He may have a point.

It's like It Is: the post says "HollowTech failures".
"Someone wrote something on reddit" without further details or evidence has the argumentative value of exactly... nothing.

The circumstances of the failures are not known, so assumptions that Hollowtech cranks are the cause of the failure is just guessing.
Amateurs guess and have to apologise afterwards.

Here's a Rudge Montague folder for sale - but don't get excited, it seems to have had the hammer and chisel treatment .... Ouch :sad:

You made a mistake in your address.
It's like It Is: the post says "HollowTech failures".

It doesn't matter which part of it is responsible.
My criticism was on the Light Religion that Sacrifies Safety to win a sec a mile in a race.

The part where is sacrificed, whether that is
- the axle (hollow)
- the crank (hollow)
- less material supporting the pedal eye (also possible on square taper cranksets - see the Stronglight I had, whose pedal eyes broke out one after another).
- or any combination of above
... doesn't matter.

Taking everything into account is what makes a diagnosis proper.

That's What I,

The same applies to your denial, Your Honor.

Hello Silva, from Planet Silva. Greetings from Earth ! Nannoo Nannoo
Don't yell too loud, your HollowTech2 axle or crank may break due to the shockwave. :tongue:

What exactly does "the same" mean in this context?

Which "denial"? That I deny to asses a failure with the solely fact that somebody somewhere made a very unspecific statement?

PS: In my perception the ad hominem stuff in this thread is rising. I don't think that this will lead to anything good.

As said here before, the dealer that replaced the bearings of the HollowTech of my previous bike, used hammer and chisel to get the drive side out.
@silva, from one non native English speaker to another :smooch:that person was not a dealer: they were a bike mechanic, or a retailer, or a distributor of a particular bike brand. At a push, they were just a guy working in a bike shop.
A dealer deals in drugs, cards at the casino, antiques, etc.
Sorry, but after 44 pages I just had to tell you!

You talk more about the discussion than the subject of the discussion, that was, the safety risk Shimano took with its Hollow Technologies:
- axle breaks that convert their HTversion2 2-piece crankset back to HTversion1 3-piece! :tongue:
> under torsion of a human left leg, damn who had thought that! :tongue:

- cranks instead of massive, consisting of 2 U's glued together, to reduce weight, that return to the state before glueing! :tongue:
> in such numbers and over so many years that they were forced "to do something", that is, a recall:

  • Notify every recall retailer of the enhanced inspection process and ensure each retailer has reviewed and understands the training materials, use a magnifying device provided during all inspections, and contact the retail assistance agent with any questions regarding inspection protocols. Court documents indicate Shimano will provide a magnifier similar to this $33 Carson device. Previous Shimano dealer recall materials recommended that retailers inspect with an 11x magnifier but did not provide the device.
  • Extend its express warranty's coverage of bonding separation and delamination by two years from the date of the settlement's preliminary approval.
  • Reimburse settlement class members who previously replaced a defective crankset for out-of-pocket costs associated with those replacements.
  • Pay each of the 14 plaintiffs, as Class Representatives, a $500 Service Award.
Even a loupe and its magnification level was determined, to discover a beginning (or whatever word one may give it) of the return to the 2 separate pieces.

Ofcourse, unlike cranks, checking for a "started" spindle break process requires disassembly, which is Veeeeeery Haaaaaandy for those that follow the note "Check Regularly". :tongue:

And all aboves crap, just to win a sec a mile, and in the case of cranks, less mass = less inertia to cope with at speed changes.
So hence the statement I made: making it a standard for any1, including Hambini's "The failure occurred in someone with the power output of a shrimp.", LOLWUT?

See Mister Ecky H, above is about the subject of the discussion, not about the discussion and not about the persons that discuss, as Some here have Shown, and continued to Show, to Try To Get Away from the Shimano Subject. ;)
