Recently I crashed my bike, and since then, the seat has been tilted towards the left side.

I know very little about bikes and the associated terminology, but I think what happened is that the rails that are used to mount the seat have been bent out of shape in the accident; see the images attached below.

What I'd like to know is:

  1. What's the proper terminology here (e.g. regarding the "rails")?
  2. Can I, or a repair shop, bend the rails back into shape without seriously compromising safety?
  3. It looks to me like the seat itself is secured to a mounting plate (which is connected to the rails) with something akin to Allen screws. Are these mounting plates standard parts that I can replace, to salvage the seat? If so, what are they called?

Thanks!

    There may be more than just bent saddle rails. The clamp (that part with the Allen bolts), the seat post head or the post it-self may have been affected. Could you post a sideways picture of the frame to the top of the saddle? – Carel Jul 16 at 17:41

    @Carel: Thanks for the additional hints! I don't have the parts with me right now, but I removed the damaged saddle and replaced it with a spare one I had, and now everything looks OK to the untrained eye. So I guess the clamp and post are fine. – RQM Jul 16 at 19:10

    Generally speaking, rails cannot be swapped unless its a high-end saddle (ie expensive). That small plastic plate under the nose will come off, but the rails will be epoxied to the rest of it. You might try to use a crowbar or a big screwdriver for leverage, but things will be weakened. Just remember to look closely with your monthly safety check and keep an eye on it. – Criggie Jul 16 at 20:44

    Don’t just look if anything is bend, also look if there are cracks anywhere. Especially around the top of the seat tube (+seatpost clamp), seat stays etc. – Michael Jul 17 at 5:30

(Saddle) rails is the correct term. They are part of the saddle/seat. I’m not aware of any saddle where they are replaceable.

You might be able to bend the rails back but it could compromise stability. Considering a new saddle only costs a couple of euros I’d just replace it.

For a crash to bend the rails like that it takes quite some force. I recommend a very careful inspection of the frame, seat post and all other parts of the bicycle.

    Agreed - a good inspection would be smart. OP might want to get a bike shop or someone else to look with a fresh eye. – Criggie Jul 16 at 20:39
