Saddle tilts right, seatpost shot?
Recently noticed that my saddle tilts more to the right for some reason. Finally got to disassemble the bits and found the cause to be the seatpost "head". It is significantly out of alignment with the post if you can see it in person. the saddle looks just fine by itself.
The seat post is a sugino 27.0. Since the head is an integrated piece, I guess I must replace the whole post? Would taking a hammer to it whacking it back work?
Also if the seat post is this bent the bike must have been crashed hard before right?

There are plenty of cheap posts on ebay. It isn't worth the effort to save this post. Also, seatposts aren't someplace to gamble on the compromised strength of a makeshift repair for the obvious reason.

In your first photo the left rail appears to be collapsed and cocked out to the side, which would lower the left side of the saddle. Does this confirm anything?
It takes a lot of force to bend a forged sea post. I'm not saying it can't happen, but . . . Try the post with a saddle you know is level and see if that works.

I can't really tell perfectly due to the shadow and paper towel in that first photo, but it looks to me like the rails on the seat are the problem. I've seen many more saddles fail than seat posts.

Those posts are nothing to get attached to , bring it to the bike shop ,
for a measured to make sure it's the same diameter, next one..

Thanks everyone, just want to report my findings.
- Seatpost is definitely shot. Mounted a brand new saddle on it and it was definitely slanted. Trash.
- Saddle rails...like you all said it is semi collapsed on the left side. Mounted on a new seatpost, did not look symmetrical. However it is not as bad as the seatpost though. keep for emergencies.
- Seatpost diameter is 27.0 by measurement. Getting a new one.
Really hope my centurion is not a crashed good. a lot of rash on the crank and pedals. Nothing on the brake lever though..

Hi,
Whilst not perfect, standing on the upended saddle and bending the whole
lot back straight via the seat post works, by bending the saddle rails.
Whether you can live with it or not is up to you.
Anyway its a good post crash tip for very bent saddles, get you home.
rgds, sreten.
I've also done it to a new cheap saddle with poorly matched rails.
