That didn't go so well...

[pdV6]

Bugger.

[Davi]

now that could have been painful

[Lord Pikey]

Thats going to hurt come winter...

[M400 NBL]

Bugger... but that could have been so much worse on a bike like that.

[RRS_Staffs]

scary

Is that the seatpost it came from the factory with though?

[neil_bolton]

Yikes.

I'm hoping you're ok?

Its the one problem with full sus and carbon posts - you tend to stay sat down 'working' the suspension, but this still stresses the seatpost.

Its the one reason I went back to an aluminium post.

shame I just sold my spare 27.2 Thomson on Monday

Its not: That bike is like Triggers broom

I think it was an Easton EA70?

Definite one for http://www.bustedcarbon.com/ there

Luckily it went on a fairly flat section of trail (the last stretch before the start of the Somme in 50 Acre Woods, for the Brizzle boys amongst us). I felt it starting to go so escaped with cuts on the insides of my knees (and a few CF splinters for fun).

It was a Ritchey post, maybe 2.5 years old? My working theory centres around the fact that I've had a couple of stacks in the last month or so that ended up with the post twisted. I guess that caused a stress at the seatpost clamp which eventually spread until it failed.

The fun bit will be getting the shards out of the frame, as the post was effectively seized in place anyway...

Any ideas how to get it out, bearing in mind it's a carbon post and a carbon frame?

Even before i opened the post i knew you had snapped your seat post finally! I thought maybe you had done while trying to get the bugger to move again as you said its been wedged in for a while. Didn't expect it to happen while you were riding!!!!

So, how are you going to get the 'stump' out?

[Davi]

I'd use a hacksaw blade vertically down inside the post to cut through (or at least, 95% of the way through) then apply drift and hammer to break one side in - or if there is enough poking out crush the tube with vice once cut through.

I'm up for hearing about this, as I've got the carbon aero post stuck in my cervelo soloist and am going for a bike fitting session this afternoon...

PS I can't cut my post... I think a plastic hammer will be my friend!

Dunno - probably try Davi's suggestion or something similar.

2nd option is a bit of welly from below as there's a little bit of post sticking out the bottom of the seat tower.

Alternatively, it's time to buy a propoer bike.

[Parrot of Doom]

If the bottom is hollow just use a cut-down cheap old seatpost to whack it out.

I reckon lots and lots of oil/penetrating fluid poured into the upside down frame/seatpost and then once left to soak, try impacting it like POD says - gently does it being the operative word.

ETA I can see you couldn't do that. You could just take a rubber faced mallet to the seatpost bottom and then get some movement that way...

Once you get a little movement, you can then use some decent grips to wiggle out the broken bit.

That or use the hacksaw like above (but that is scary).
