Would you still ride with the seatpost?

[The expat cyclist]

I will post some pics when I get the post back but the story is this:

Bought a used bike. Bottle bracket mounts to the seatpost. Previous owner clearly over tightend the mounts and this left groves on the post.

 

Because I work for a company that supplies medical equipment, I had this x-rayed by one of our techs during a quality assurance test. It showed no cracks on the carbon. None at all.

 

Would you still ride with this seatpost?

 

Replacement cost for the same is R2.2k

No I would NOT

[Grease_Monkey]

Nope - chuck it. You can get much cheaper carbon seatposts than R2,200 that will be just as good.

carbon and allow options

Broken carbon seatpost sounds like a pain in the @ss...

[Beattbox]

Replace it. I had a carbon seatpost break 40km into a 200km ride, not nice. Don't take a chance on it.

Definitely replace it, X rays are not great at detecting small cracks/defects in carbon fibre assemblies.

 

Ultrasound or electromagnetic testing is better.

Carbon not cracked.... ride it if it's a road bike, not if it's a mountain bike. (No technical reason, only cos it's easier to get an Uber).

50/50 - depends on how bad it actually is. If it is just a slightly compression mark then it could be just as strong as the day it was sold. Carbon doesn't dent so it might even just be the clear coat or paint over it that is marked from the mount with no impact on the carbon.

 

There are very few carbon handlebars (primarily referring to MTB here) that won't show any marks from the shifter or brake lever mounts... It doesn't mean they are damaged.
