Clydesdales/Athenas (200+ lb / 91+ kg) - Quick Seat Question

I raise the seat about 2-3 times every ride because it always winds up lowering (I'm assuming) because of the bumpy roads and what not. I tried tightening it myself and even had the LBS dealer tighten it (said that it "definitely won't happen again"...it did lol) to no avail.

Anyway, are there any tricks/methods to keep the seat in place no matter what? I don't want to ruin the frame or the seat, I just wish there was a way to keep it at the level I set it for at least one full ride. I was thinking about maybe super gluing it or something? But then realized that I may somehow damage the bike. Any suggestions/help you guys can send this way would be greatly appreciated, 'cause this is getting annoying.

Thanks,
-Anthony

Try removing the post, use a degreaser to clean any grease that may be on the post and inside the seat tube... the creeping of the seat post like that is one of two things, either too much grease or the seat clamp is not providing enough clamping force. So clean the seatpost and seattube, and if that doesnt work have the LBS switch out your seat clamp.

For theft protection, I just replaced the QR with a 6MM grade 8 bolt & nut. You can tighten it down much tighter.
Once you have established seat height, who needs QR anyway?

The only thing a QR is really good for, is to quickly release the seat while some #$%@ is stealing the seat, which then comes with a nice post as well. To prevent you seat from being stolen, simply use an Allen head bolt, then when the seat is properly adjusted, fill the hole with high heat hot-melt glue or solder. If you really need to remove the bolt just melt the glue/solder and use the proper key.

If using an Allen head bolt, use only the proper key to tighten, some people use a pipe to add leverage, this can deform the metal or crack CF seat tubes, and that can make it even harder. An option for preventing the seat from crawling down, if your post is black, get a can of black metal paint, mask off the bottom part of the post at the right height, now give the top part of the post about 4 coats of paint, this will increase the diameter slightly, making it much harder for the post to slide down.

Thanks for the advice, guys. I think Iamkar33m is right, it seems very greasy. I will try to remove some of that and see what happens. Thanks again to everyone. :)

You can make a shim from a coke can.

please let us know what works. there are some good ideas posted here.

Ha! Practical AND attractive. I would use a beer can. Fly your flag, right?

You might be able to find a clamp that will fit on your seat post. Tighten it as usual, then slide the new clamp down to the top of the seat tube, but NOT over it. Tighten it up, and you are done.

good thread - i have the same Q right now.
