Crank

See other failures under 000.html.

From http://gallery.consumerreview.com/webcrossing/images/061003013.jpg as of 2004/01 with no commentary. Appears to be a Race Face crank of unknown type and history.

I had the exact same thing happen to my next LP set. It took a while for what happened to sink in. Hmm, foot's off pedal, musta slipped out, Hmmm, can't seem to find pedal with foot. Damn, pedal's still on foot.

[T]he crankset was 8 months old. To answer the [just riding along] question, I had just stood up to pedal up a short hill..jra.

A buddy of mine was "just riding along" when his bars broke due to fatigue. He's damn lucky to have a face now.

A fourth post by ``Pete Cresswell'' says

About two hours into a 3-hour ride, stopped to bum a cup of coffee and smooze with some people I know.

Got back on, started riding away, OOPS!....

Inspection of the break revealed dark areas around one side - indicating that there had been a crack there for long enough for the metal to corrode/discolor.

And my riding style is somewhere between extremely-conservative and just-plain-pathetic. A 10-inch curb is a big drop for me and I never jump the bike.

Now I check my cranks for cracks.

A fifth post by ``Klydesdale'' says

This is why I don't like black colored aluminum parts. It's much easier to see these stress cracks on polished aluminum and catch them before they fail catastrophically. After breaking a couple of crankarms, I've implemented a polish and inspect regimen for them as part of my regular maintenance.
