New Dropper Post Creaking

[Cassinonorth]

Ordered a new dropper last week after my Command Post shit the bed. Looked up the specs for my frame, 30.9...cool. Order the new dropper and it's 31.6. No worries, I have a shim in my parts bin. Installed to torque spec, no play in the seat post at all. Take a ride yesterday...creaking like crazy.

Is there any option beyond trying to exchange it for the right size post?

Also... maybe lube the pole, hot the hole?

I think I worded that incorrectly. Spec said 30.9, ordered 30.9. Turns out the frame is a 31.6 so I needed a shim. Now creaky beyond belief whenever I'm pedaling.

Also I somehow created this in the off-topic forum. Rough day. @Patrick pls help.

Yes, used plenty. Now what about my bike?

Can you have somebody sit on the bike and move around so you can listen and source the noise? It could be the seat rails too, which are often missed. Lube em up.

Shims aren't the best, especially on droppers. Definitely can see more possibility for noise.

Had that thought as well. Going to pull it tonight, regrease it (friction paste since it's a carbon frame, right?), tighten everything else to spec and see where that takes me. If it doesn't go away I'll just sell it or see if they'll exchange it since it can pass for new.

Fiber grip inside/outside stupid shim.

This. ^

Also, friction paste is probably going to scratch the shit out of your post when you try to take it out. Won't look brand new anymore.

I'm assuming the shim is alloy, so if the frame is carbon I would go with carbon paste outside the shim and anti-seize inside the shim, if the frame is alloy anti-seize on both sides.

Is it too late to exchange the post for the proper size?

Reached out to see what they'd say, no issue even with me missing the original box. Guess we'll never find out if this issue could've been solved.

PNW Loam...the one ride on it I much preferred it to the Command Post.

I'll be replacing it with the same...they don't have the 31.9 in 170 so I'll be probably going 200mm and using their micro adjustment to drop it to a 175mm dropper.

Yep, standard PNW procedure, send it back we’ll send you a replacement. I believe now it’s for the lifetime of the dropper post. Not sure if it’s worth the mark up from the equivalent Tranz-X but it’s nice enough for sure. And they are always great to deal with.

i like my pnw too. The lever is awesome.
I had a command post on an old bike. It was definitely one of the most reliable posts I’ve had. But it started leaking air and that was that.
