r/bustedcarbon

Hi, noticed this crack a while ago, but its getting bigger…
Is it time for a new frame?

Ordered a pair of secondhand Hunt 38 Carbon Wide Aero rim brake wheels off of Facebook Marketplace. Listed as being in good condition but they've just arrived and there is this flake/chip missing on the rim bead of the rear wheel.

Done the coin test and everything sounds fine and the damage seems fairly shallow, anyone have thoughts on how worried should I be?

I was checking whether the saddle-clamp bolts were tightened to the specified 8 Nm. The front bolt clicked at 8 Nm, but the rear bolt kept turning without the torque wrench clicking, so I stopped. Afterwards, I noticed these marks around the clamp bolt. Is it safe to keep riding, should I have a bike mechanic inspect it, or should I replace the part?

Is this a crack? I can't feel anything under my finger its completely smooth and i tested it with coin tap... any other way to test is it a crack?

It's only visible from a certain angle

Got this bike secondhand and already like this from the previous owner. only ridden it around 50km. At first I thought it's just a scratch that I can ignore because it's my first time having a bike with a carbon component.

A lot of people alredy told me to me replace it.
