Need Help
Hello All!
I have a Jamis Citizen 2 and I noticed my saddle keeps on tilting back and the bolt needs to be tightened after a 20-minute ride. I tried taking it apart and cleaning it and reinstalling it but I think I need a whole new 1 bolt saddle clamp. No matter how much I tighten it -- it only holds for 20 mins until it slips again. I am completely lost on what to do. I cannot tighten the bolt anymore since I ended up striping the head of the bolt. If anyone can just send me the link of what I need to purchase. I would really appreciate it. |

since I’m new I have to post more on here to attaching photos unfortunately |
Without seeing it, I’d guess the aluminum clamp at the top of the seatpost has deformed and will not clamp tightly any more. Often happens if it’s ridden loose. You can try and find replacement clamp hardware or you might just have to replace the seatpost.

Ditto the above. Take it apart, maybe you'll fine some serrations are worn, maybe something got bent out of shape, like two curved surfaces no longer match. Some things can be fixed in a vise with a hammer (be very careful bending aluminum), some things can be cleaned with a file. Maybe the bolt threads are galled and aren't really tightening as much as you think.

I'd take it apart and look for damaged threads on the bolt and nut piece. If they're damaged, replace them; if they're intact, try Loctite.

Does that seatpost have springs, or a quick adjustment drop?
Do you need the seatpost to have springs? I'd remove the seatpost, and check to see if it is marked with a size, somewhere near the top of where the post goes into the seat tube. Is it marked with 27.2? Another number? I'd probably look for a replacement post that has a different attachment method. Many of the 2-bolt posts are zero offset. Will that work? Also, have you been having issues with the seatpost slipping down in the seat tube? I've ridden a road bike for most of my life. One thing I am is very careful about what I run over. Heavier bikes are more forgiving with running over stuff, but it is a good idea to "unweight" the seat when you have a big bump. So, stand up a bit and using the legs as shock absorbers. |
thanks so much, everyone! I will take it apart tomorrow like suggested. Appreciate all of you!

Thanks so much Clifford! No issues with the seatpost slipping down the seat tube but I will take apart tomorrow.

You need a new seatpost. I have never had luck making them work after the serrations are ruined.

I would just replace the thing, it was a pretty cheap seatpost to start with and a poor design in general (think pogo stick). If you are looking for more comfort I would look at the Kinekt seatpost which is tunable and isolates you from vibrations and bumps. If you are just looking for a cheap post head down to your local shop and they can order you a cheap but decent enough 2 bolt post which will help in the long term, or if they have one they can sell you one right then and there. 2 bolts are going to give you a bit more adjustability and reliability.

I agree with replacing the seat post. I almost always get rid of the shock type when they come into the non-profit shop. Every one is loose.

Serrations on the clamps is what keeps a saddle from nosing around, the screw only needs to be snug to do its job.
If you feel you really need to tighten that screw beyond torque specs, that's a sign to get a new seatpost. Seaposts are really inexpensive. The elastomers in your saddle should be enough without the need of a suspension seatpost, which are also very heavy. |
