How often do seat posts break, and where? Mine (on a 4 yr old Trek 520) gave way the other day, snapped off horizontally fairly cleanly near top of tube, just under the goose neck. Wasnt doing anything very strenuous, just riding to shops. LBS inspected the break and opined it had been cracked for a while before going. I thought alumimium would probably just fail all of a sudden, without a crack. Must admit I did have a prang 2 years ago where bike did a cart wheel and landed on rear of seat. Demolished the seat but everything else seemed OK. Now I am worried that something else might go. The new seat post is much longer than the old, LBS said to cut it off if I wanted to.
Gal at werk busted her CF seatpost on the Footscray Rd path this week. Being a sponsored AIS rider it was more an inconvenience to her short term than $-wise.

Ok I am trying to get my head around a seat post cracking and breaking, there is the possibility of some pretty "haenous" injuries is there not ???
Or do they break in a way where for some reason you don't accidently sit down while the seat is no longer there ??

I had a bout of testicular trauma when a Real Design carbon post failed. The clamp was metal on carbon, both splined - more like Real Dumb Design. I hit a bump with my weight back on the saddle. The carbon splines let go and the front of the saddle pivoted up and smacked me in the nuts. Youch! Needless to say I only had to issue subtle threats to get a refund.

The triathlete Jan Rahula, training in Sydney a few years back, had his seatpost break on a training ride. The jagged end pierced his rectum and he suffered pretty substantial injuries and blood loss.
Think on that the next time you park your [censored] on top of your ultra-light- weight wonder of a seatpost...

Not terribly often.

Bob boom, I was of course hoping for a long dissertation on metal fatigue and bending momnents.
I remember a rider on the last day of a Big Ride, from Milthorpe to Bathurst, riding without a seat. Always wondered if it was for a dare or he couldnt get a replacement post. Looked bloody tiring. Its hard to steer too.
Anyway the bike shop gave me a cost price replacement. Now I hope the stem doesnt go. It survived the Gong Ride yesterday.

There's a joke here somewhere about only having one ball left and hence being able to go faster, but I can't see it.

To be sure, I was laughing and crying at the same time.

I had a carbon post break under me when I went over a bump on the road. Basically, it pivoted at the rear of the seat tube clamp while I was on the saddle and my [censored] pivoted down towards the rear tyre (but didn't quite get there I'm happy to report).
Replaced by importer. No questions asked, other than whether I was OK.
