    Having some trouble with my saddle

    Ello! I've recently started having trouble where my bike seat will tilt back on it's own. I've tried tightening up the seat when I move it back to it's proper tilt, but it tilts again soon after. I've taken it to the LBS, and they say my seat post is fine (I thought I might need a new one) and they tightened it up for me, and it was good for the first 5ish miles before it tilted again. The LBS isn't sure what to do, but they are sure that the seat post and it's components are in good working order and don't need to be replaced. Should I replace them anyways? Or is there something I can do that doesn't involve replacing the saddle, stem and such? The seat was fine until Tuesday when it started doing this, it was rather windy but I don't think that has much to do with it. It makes an otherwise enjoyable ride quite annoying and even a bit painful.

    Any help would be appreciated.

    Well seeing how you said your LBS tightened your seat to the post, and it loosened up again, try taking the bolt off and check to see if its stripped both the bolt and the clamp itself that holds it on the post. Your LBS should've done this but if they were in rush and just tightened everything it's possible it's stripped. If it's stripped, go to a hardware store with the bolt and get a replacement of the same size - should only cost a couple cents (50 cents at most). Your LBS may be able to give you a new one at no cost if you ask nicely, but no guarantees.

    Your LBS have got to be idiots - how can it be fine if it's not staying put? Seriously, that doesn't even make sense.

    Some seat posts have little teeth so that when you tighten it up, the teeth interlock and your saddle stays put. Check to see if they're worn down.

    Honestly, I've never had a saddle that didn't stay exactly where I put it.

    Wash the parts that might be subject to moving. Sometimes a light layer of grease is applied to parts to prevent corrosion. If the parts become dirty and gritty you won't get a solid contact that can hold tight.

    The Bolt is good, and so is the clamp or at least it appears so. Though I do notice a bit of damage on the portion that comes into contact with the seat post, looks like the paint came off when it moved.

    I'm a good bit larger than most people, and the saddle was fine for a good five miles where as when I had tightened it up it only lasted a mile or so. They aren't idiots for not seeing the problem, and it appeared to be a quick fix that worked for the mile or so I rode my bike after having it looked at by them. There are no teeth that you mentioned, thanks for the suggestion.

    There was a good layer of grimy grease on the bolt it's self. I washed off the seat and found it did have some on it as well. I'll update this next time I get to ride with if this helped or not, not taking it out tonight but should be able to do so tomorrow. Thanks for the suggestions so far!

    I'm sticking to my guns - if your saddle isn't staying put then it is not right, at least not for you.

    take a picture, if you wouldn't mind. If you're 400# I'd expect you to wear out a seat post more rapidly than normal but if it's still good, it won't move.

    Trojan Horse is correct, pictures would be a big help.
    Without those, my first inclination would be to get a new seatpost and clamp anyway.
    If you're confident the LBS folks are correct in their assessment of mechanism, then my guess is the clamp is a bit worn and is no longer robust enough for a heavier rider ( but possibly just fine for a 135 lb racer).

    But this is just a guess. Pictures please.

    Sorry about not getting back to you guys, but I've not had any problems after cleaning off the gunk as suggested by Dave Cutter. It seems that was the problem as I haven't had a problem with it his entire week. Thanks for the suggestions and help, I'll try and remember to update things in the future as I can be kind of bad about those things.

    good that the cleaning fixed the problem... with the cheap single bolt posts the teeth have to interlock with each other to stay put... one reason I gave up on single bolt posts years ago... they are fiddly to adjust and have no fine adjustment between teeth... when it comes time to upgrade pick up a 2 bolt adjustable post... makes fine tuning the angle SOOO much easier

    Thanks for the advice, I'll look into a 2 bolt adjustable when the time comes.

    When I do upgrade any suggestions on what to look for? I'm not worried about weight more worried with durability at this point. Thomson Elite is one I'm currently eyeballing, Thomson Bike Products | Elite Seatpost Series .

    While I still haven't had any troubles since I cleaned it up I'm getting paid soon and don't mind investing in something that would make my riding more enjoyable/worry free.

    i've never had a problem with a seat tilting back once it has been tightened. seat post sliding down the seat tube yeah but not tilting back. if you've sorted it now and its stuck in place its debatable how much more enjoyment a new seat post will bring you. maybe spend your hard earned cash on something else!

    Glad that fixed you up. I am a big believer in keeping my bicycles [and other equipment] clean and well maintained.
