would you ride this seat post?
i pulled this Campagnolo SR seat post out of the frame is was originally STUCK in, put up a decent fight but i won
the frame is now saved, but the seat post shows some nasty scarring from corrosion (1/32in deep MAX), only in the area shown...

i would probably ride the thing near the limit line, so it's pretty useless to me but if it were inserted into the frame far enough to cover that mess would it be safe?
the very end of the tube (1/8in MAX) was cut off because i was crumbly, even still then end is a bit soft.
is it a total loss?

If it were inserted past the pitting above the limit line then I think it would probably be safe, but if that part is above the frame then I would not... it is possible it might work, but the potential damage caused by a snapped seatpost says to me it isn't worth any sort of risk.

I certainly would not tell anyone else to use it, but I might if I little choice. I certainly think you need to insert it above the word 'limit' to make up for what was hacked off.
you need to inspect the inside real good somehow.

^ good point mentioning it's been hacked short.. i thought the limit line looked pretty close to the end of the bar
i'd use it but not at the limit line thats for sure

i wouldn't say it was "hacked short", i cut off less than 1/8in (probably closer to 1/16th) as it was semi crumbly and ugly, using a fork steerer tube cutting guide at my LBS.
also, thanks for all the input. as i mentioned i could never use the thing as i typically run these SR posts close to the limit line, but if someone wanted to use it (while inserting it far enough to cover the ugliness), i wouldn't want to give away an accident waiting to happen.

Those seatposts aren't known for failing and the wall thickness is fine, even with the section loss. I would happily ride it.

I had a C-Record post fail on me. It gave me a real scare. I was riding quickly at about 50kph when it went. I nearly went 'out the back door' but managed to stay upright. Retrieving the post, it showed no evidence of prior damage - no marring at all. It just snapped.
A week prior to my incident, another rider from my local area had it happen to him with a Campy post. He, unfortunately impaled himself on the piece that remained in the frame. He had to have major surgery and now has to wear a colostomy bag. I did not see his seatpost and I do not know which Campagnolo model it was.
I'm a real fan of Campagnolo but it does have its faults. I would not use that seatpost.
It is your choice - best of luck,
Gary

That seat post isn't going to fail on you. I'd use it (after I cleaned and polished it up). What size is it? I could use a 26.2mm.

With the corrosion above the seat tube, I'd be concerned about all the crack initiation sites. It would just be a matter of time until a crack propagates through the wall of the seatpost tube. Theoretically you could sand and polish out the corrosion, but the reduction in wall thickness not to mention esthetic result may be a deterrent.
