View Full Version : To much grease on seatpost?

I read the manual that came with my bike, Trek 4500 if it even matters.
It advises to apply some grease to the seatpost yearly I believe. Well, I have only had this bike for about 2 weeks I think, but I adjusted it to the exact right place I wanted it, and about 5 miles into every ride, I notice it has lowered about an inch, and pedaling gets very inefficient. The frame is the correct size for me, and the seatpost isn't extremely far out of the frame, there is probably about 6-7" rough estimate showing when it is in the right place. I noticed there seems to be a lot of grease on the seatpost. Would it be ok to wipe some of it off, to maybe avoid this problem? Is there such a thing as too much grease on the seatpost? I already made sure the quick release on the seatpost is closing securely, it seems to be about as tight as it can be without being too tight, and stripping it out or something.

Just wipe some of it off. Its important to have some grease there so that the frame and seatpost dont fuse together.

cool, thank you for your advice. I just took the whole seatpost out, and noticed gobs of greenish looking grease all over it. I reduced it to a thin layer, I will test it tomorrow on my after work ride. Dirtbike, I'm glad you said that, Don't want the seatpost fusing, I almost wiped it dry, I appreciate it!

It really shouldn't matter, excess grease gets pushed either to the top or bottom when its clamped properly.

Quick release seatpost binder? Or bolt clamp?

As seely said, no such thing as too much grease. Assuming the post is sized correctly for the frame, either the clamp is tight enough or it's not.

If it's a QR, you may have to tighten it more. Er, same goes for a bolt-on, yeah.

my newest bike came with gobs of grease on the post, but I never had a problem after getting it really tight, and wiping off the excess that seeped up aroung the collar.

Agreed. Sounds like the clamp is loose

The grease is also there to stop water seeping into the frame.

Make sure there is some grease along the hole post and wipe off any excess. Some guy in Aus had a Turner DHR get a seatpost stuck in it... Let;s just say that the company that got it out had a lot of fun using a pump, welder and target;)

Tighten your quick release. Screw the thumbscrew a couple turns and retighten. It should be fairly hard to close.
