Most of the seat slipping issues i've seen are on a different type of clamping system. D shaped seat posts with the little wedge piece clamp are the ones I've seen most. I built a Cheap Carbon bike for my channel and had similar issues. But NONE of the normal solutions worked for me. I had to use a combination of paste with a folded paper wedge. But the type of clamp you're using here doesn't usually have these sorts of issues. Not in my experience anyway. I do appreciate the content though.
And me, a brand new bike! Dealer a reputable one at that, says he will contact Giant for advice? what is going on ? on my old bikes cleaning and a good tighten always worked, must be like every new product so full of tech it doesn't want to work in the real world.
1: Take it apart as much as possible 2: Clean everything 3: Apply anti seize compound (if your on an alloy frame, assembly compound on carbon) to the surface between the seatclamp and the frame 4: Reassemble and reinstall the seatclamp. Be sure to apply some grease to the screws and switch them out if they are rusty. 5: Apply grease (alloy) or assembly compound (carbon) to your seatpost 6: Reinstall seatpost 7: Tighten the seatclamp. It does not need to be too tight. If the saddle doesn't move, you're fine. 8: Done
I've been having problems with the seat post slipping on my new aluminum frame bicycle. Until now, my solution was to torque the clamp to the maximum of 8 Nm, an obvious mistake. I will follow your suggestions, THANKS!
My aero seat post slipped even with carbon paste on it . The tolerances were out quite a bit. I got some anti slip tape which is basically sandpaper with a sticky back and put a strip of that on the back of the post then put carbon paste on. It's not budged since.
I have to say what a great video so easy to follow the steps and what to do with the post ect and just the little tips about the torque wrench ect brilliant thank you
I just used a piece of the rubber that comes with light mounts rolled it stuck it in hole then stuck post in. solves any slipping but a devil to pull out.
This is wonderful! I have a pinhead lock that i have been busting my hand trying to lock it down multiple times as it always sinks the seat. I will buy these things right away! Has anyone else had problems with pinhead seat lock sinking down?
I'm having some trouble with that right now. I just overtorqued it before watching this video and it doesn't sink anymore when I sit on it, but it still rotates. Going to give the compound a shot.
I always put plenty of anti-seize inside the frame where the post goes in and on the seat post. Talking from experience!! Getting a stuck post out is not fun. A lot easier just to put anti seize in there. I got a QR Aluminium seat post clamp.
On my old bike from 1984 I have the opposite problem. The seat post is completely stuck in the frame, probably due to a galvanic reaction between the CrMo steel frame and the aluminium alloy seat post. Any ideas of what to do about that?
