Ouch.

This *could* have been painful... my carbon fiber seatpost broke off, at the frame, while seated and going over a bump (actually a pot-hole). Fortunately, I caught myself as soon as I had the falling sensation, and fortunately there were no sharp protrusions, and fortunately I was able to remove the stub from the frame, and fortunately I had a good, reliable Thomson post that I could use as a replacement. Whew.

Check out this little story from Cyclingnews.com to see why I used the word "fortunately" so much:

Czech triathlete and Olympic bronze medallist, Jan Rehula, suffered one of the worst possible consequences of a seat breakage after a training accident in Sydney recently. 27 year old Rehula hit a pothole, snapped his seat, was gouged in the rear by his seat post and lost two litres of blood.

He has so far had two operations and has internal damage in his lower back. His start in the Hawaii Ironman triathlon in October is in doubt, but his spokesman said that he was quite positive that he will be able to resume his career.

Yikes! I'll stick to metals...
