Intact. To answer Carla's question, the crankset was 8 months old. To answer the jra question, I had
just stood up to pedal up a short hill..jra.

What about stress risers and inclusions? Dark material on the surface of a break does not have to be
oxidation from crack development. Consider the multitude of failure modes.

C'mon, that's too hard for an underdeveloped and overanalytical mind to grasp. I prefer to just tell
him to piss off.

So, you routinely "polish your crank" eh?-)

Don't kid yourself, humpy. It stops right at you, which is the bottom of the barrel of bottom
feeders. You don't count, just like all of your leg humping butt buddies.

Don't have to worry about that. SWMBA is more than glad to oblige.

DaaaYUM! Can you say "torque"?

Dude, you are making me nervous with the 13-yr-old Suntour 175s on my SS. Perhaps it's time to
upgrade...uh...but my upgrade candidate was a Race Face! DOH! :-)

Please heed the next to final paragraph re: "We used to figure that smart riders replaced their
equipment, especially bars, on a prudent basis."

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