Suggestion for super thin shim on a 31.6 post?

[Dude]

Assuming the post is the correct size, you can also look at the seat collar. Some of them aren’t that good.

Yep I need to get a new one of those, my favorite are Campy. Gotta see if they make in that size. The OEM aluminum collar was Cannondale and I snapped the bolt head. How far outta spec I dunno. Used rotchey torque key which goes I think to 5.5, then i did a slight addtl turn with allen wrench. Then…pop went the allen head.

The collar i ended up using is carbon fiber of all things, had one in the parts bin. Forget the brand. Torqued to about 6.5.

If I had a nickel for every time someone responded to me with "I got it on Amazon", after one week I'd be able to afford a full Campy Richard Sachs!

Get a seatpost adapter with class.

I own a bike with a Cane Creek adapter and I approve this message.

I wouldn't think Cane Creek would be able to offer a USA made seatpost shim for $11. That's a good deal.

Do they say these are made in USA?

I was always under the impression Cane Creek made everything in the USA, but learned that most of what they sell is imported.

Funny thing is the Amazon shim looks identical to CC shim, down to the machined texture on the cylinder and laser engraving (font).

As for comment on killing the economy, CC somehow finds it ok to offshore manufacturing and resell parts stateside with value add of a warranty (where applicable) and a logo. Perhaps take it up with them? Not solving that here….

worked it in super slowly with 1/8" back and forth and downward pressure. quite the workout....

thanks for all the tips!

How dare you recycle things and kill the economy!!

truth speaks the truth.

I had a really wonky seatpost situation before and used one of the "double" clamps that has an extra clamping ring above the seatpost collar to clamp onto the actual seatpost. Looks chunky but works great.

Yeah, you're right. I brain farted and was thinking reducing down to a 27.2.

You can have someone knurl an aluminum japanese knives post if they have a tool to do so, that will take up some of a loose fit and add grip, or the coke can shim. Anything more than a couple tenths of a mm would likely be too much if everything is pretty close to spec.

You're diving into some detailed troubleshooting there!
