Bontrager Seatpost

From Steve:

Anyway, my contribution is nothing overly dramatic as some of the entries are by any means but it’s still busted carbon. This shot is of a friend’s seat post sometime after he adjusted the saddle height. My guess is the possible over-torque of the clamp at the old height. Just a guess; either way, it failed.

Still, a broken post can be unpleasant.

Another broken seat post

B.N. sent me a photo of his Pinarello Paris with a seat post that lasted less than 500 miles.

Cyclocross vs Carbon Seatpost

Steven sent me this photo of a carbon seat post that failed during a cyclocross race. If you are going to be leaping onto your bike 15+ times per race, you need a strong seat post.

FSA Carbon Seatpost

From James:

FSA post on a Marin Mount Vision. Going over a fairly small (c.18” bump), seated and slow.... a little creak... then a full-scale snap! Just outside warranty too. And no, I didn’t impale anything!

2nd Busted Look Seatpost

From Richard:

The brief story is my first Look seatpost broke after 2 years. The Look replacement (warranty) broke in 10 minutes at the exact same location. Look is scratching their head and generally not wanting to replace the replacement. For the record I weigh 165 lbs and ride a Look 585.

10 minutes has to be a record.

Busted Seatpost

Jamie sent me these photos of his 18 month old carbon seatpost that snapped.

Since today is supposed to be a No Carbon Wednesday, I'll also include a photo of his broken front derailleur.

Carbon Seat Rails

Someone over at Pinkbike.com broke his carbon seat rails.

Another Casualty of 'Cross

Another 'cross race, another broken carbon seat post. 

Look at the Seatpost

It's broken.

Race Report: Cameron Cross

Damage report: One seat post, one steerer tube.

Quote from Stephen Kilshaw: ...pre-ride the course. On my way up one of the steeper climbs I literally pulled the handle bars right off, cracking the carbon steer tube in half. No joke. Just pure torque from the arms managed to crack this thing climbing the hill.
