Hey TOM! we're taking bets on what you will change the subject to when
Frank replies to you (and shoots you down again). Care to get in on
the wager? Right now $0.10 gets you $10.00 if you guess the subject
correctly.



I wish that this thread was still about someone having a Suntour Cyclone bottom bracket spindle they would be willing to part with. ;(

Sure doesn't take long here for a thread to be hijacked. That's what it is even though Frank insists it's just topic drift.

Here's a vintage chromed one for only twice the price of our
new black finish spindle:

Thanks again Andrew. I already have a few Shimano bottom bracket spindles I could use. However, I really do want to restore this bike to all Suntour Cyclone components which is why I bought the NOS Suntour Cyclone BB cups when I saw them at a nice low price.

Cheers

I'll look, because I still have a Cyclone crank -- but I bet the BB is long gone.

It would help if you quoted the stuff you're objecting to. Frank's
point, if I understood it correctly, was that strength != stiffness.
Chalo commented on a lack of stiffness in some obsolete bottom bracket
format or another, not a lack of strength.

I believe Frank would say that CrMo and mild steel have approximately
the same stiffness, and also that he would be right.


Correct.

I don't think Tom understands the difference between strength and
stiffness. And as usual, he's misstating my points in general.

No joy. I got rid of a lot of my really old stuff, so I'm not surprised. I did find a 113mm Phil BB. Kind of rusty with somewhat rough bearings. A classic from the 70s-80s.

While it is easy to say that the Young's modulus of ferrous materials is "about the same" it isn't the same and the higher grade materials are indeed stiffer if not by much. But these higher grade materials allowed for large improvements in power transfer.

"Is that true"? Always a valid question when dealing with Tom, so just
let us in on your reference so we can determine whether this time Tom
is telling us the truth; or just another lie?

Now that you've googled "modulus of elasticity," why not give values for two
alloys we were talking about? And why not give the percent difference? Quantify!

I ask because in reality, the differences are tiny.

But these higher grade materials allowed for large improvements in power transfer.


Explain. If you take a bottom bracket axle made of steel with yield strength
100,000 psi and replace it with an identical part made of steel with yield
strength 120,000 psi, will it transfer more power from the same rider?
