"Fatigue is a stochastic (http://en.wikipedia.org/wiki/Stochastic) process, often showing considerable scatter even in controlled environments.
The greater the applied stress, the shorter the life.

Fatigue life scatter tends to increase for longer fatigue lives.

Damage is cumulative. Materials do not recover when rested.

Fatigue life is influenced by a variety of factors, such as temperature (http://en.wikipedia.org/wiki/Temperature), surface finish (http://en.wikipedia.org/wiki/Surface_finish),

presence of oxidizing (http://en.wikipedia.org/wiki/Oxidizing) or inert (http://en.wikipedia.org/wiki/Inert) chemicals, residual stresses, contact (fretting (http://en.wikipedia.org/wiki/Fretting)), etc.

Some materials (e.g., some steel (http://en.wikipedia.org/wiki/Steel) and titanium (http://en.wikipedia.org/wiki/Titanium) alloys) exhibit a *theoretical* fatigue limit (http://en.wikipedia.org/wiki/Fatigue_limit) below which continued loading does not lead to failure.

In recent years, researchers (see for example the work of Bathias, Murakami, and Stanzl-Tschegg) have found that *failures occur below the theoretical fatigue limit* at very high fatigue lives (109 to 1010 cycles). An ultrasonic resonance technique is used in these experiments with frequencies around 10-20 kHz."

I guess it "is" possible, even below expected limits. That's why I've seen even steel frames crack. Meh. Carry on.

Again, I vote Cross-Check! A single-speed complete version comes out sometime the end of this month! Single-Check!
