Carbon post damage?
Hey guys,
I managed to trade in my previous bike for tcr advanced sl 1 disc 2020. Extremely happy how it rides! They cut the seat post to my dimensions. Im just putting it together when i noticed slight damage on the post where they cut it. Is this a concern? Just as expected during cutting process? The forum doesn't let me attach pics. . The paint has been chipped and maybe some carbon fiber on the outside.

I agree, as long as there is no damage in the clamp area it should be fine.

The post may be fine but keep in mind the poor attention to detail in the event of possible future work done on your bike by that shop.

Not sure what they did at the front edge - what looks like a cosmetic outer layer has detached a little. However the CF underneath looks undisturbed. Personally, I’d have no concerns with cleaning up the cut edge and just using it.

Honestly that looks to be a bad job at cutting by the shop but it does appear to be just on the surface. You may want to cover the area so moisture does not get behind and saturate the carbon.

I hope you don't mind me asking this here. How do you attach the saddle to the seat column?

a little wet or dry sandpaper & water, can clean up the edge , but wear your mask while doing it,
as your lungs are seeing carbon dust in the same way they do Asbestos.
or silicosis.
sanding wet keeps the dust down..
basically the cutting was back to front, same thing happens when you cut wood ...
with a saw,
never cut wood?

I'd apply resin over the exposed cut area to seal out contaminants.

This thread is strikingly similar to one on RBR, except no one suggested to use nail polish over here, yet.

1. Chipped carbon shown in the circle on the left
2. Lillie gap in between carbon layers shown in the circle on the right. When i press from the inside of the tube i can see the carbon layer moving.
Do you still think this is not an issue? I've asked the shop for a replacement but they have been very hard to talk to (e.g. "we're looking into it" etc..).

Hey mate, i thought I'll attach another picture as it provides more clarity. I drew 2 circles around the issues I'm concerned about:
1. Chipped carbon shown in the circle on the left
2. Lillie gap in between carbon layers shown in the circle on the right. When i press from the inside of the tube i can see the carbon layer moving.

Yessir. A composite-specific blade will be a "burr," with carbide or diamond grit instead of teeth. You can "get away with" using a 32T, but there's still a chance it will snag the fibers. If I were to guess, I'd say that shop maybe used a dull 24T, and possibly even an 18T. Absolutely the wrong tool for the job.
