Looks like just a paint chip?

Paint Chip or Carbon Crack?

Enable HLS to view with audio, or disable this notification

First carbon bike frame. Purchased second hand. First ride on some root filled trail and had a bit of a hallow crunch/pop sound. Thought it was my seat tube so I careful tightened that. Could still be what the sound actually was. However it was still happening after tightening and when putting the bike on the rack to go home I noticed this fun little crack in the paint. You can clearly see there is a slight bubbling up of the paint and a crack. When tapping the quarter there is definitely a sound change but I’m asking; does it look like it’s the sound change of a paint chip changing the sound or is it a carbon crack? Should I get my nail under the chip and flake it off or take it to a local shop for further investigation? Any advice is welcome.

Steerer Compression Marks

Are these compression marks on my steerer anything worrying? I can feel it when i run my finger over it, but tapping it sounds normal and there is no flex. Has always been torqued to 5nm.

Is there anyway to really tell if it’s fine or not?

TIA

Damaged fork after a fall on friday.

Surprisingly nasty fall on a flat / v. gentle uphill. Chain jammed for a second - and I was in flat shoes just cruising over to a local cafe. Basically slid straight off the front when it jammed, onto my head, face, elbows, hands, then knees. Loads of blood, and a fair bit of superglue to put be back together. 🫠.

Anyway - the important stuff. This is on the fork. Can see the tire and the "Conti" logo for scale. Crash was around 25km/h, and this side of the fork was on the "Up" side, not the road/down side when I hit the ground. Me and the bike then tumbled.

Any thoughts on wing-it, repair-it, or bin-it? TIA!

Top tube damage from fall

My (carbon) bike fell down from being stationary and hit a grocery store cart. Noticed later on that my top tube took a hit. What do you think, is it just cosmetic? PPF was pushed away as well from the impact area.

Just cosmetic?

Just realized while cleaning my bike that it has some scratches. And paint chips. When I press my thumb into it doesn’t flex. I think it’s safe to ride what do you guys think?

Put my new frame (literally one ride) on my turbo trainer for the first time and didn’t check if the through axel hole was aligned before screwing, heard a crack and saw this… any ideas if it can bear load or should I remove it and take it to get fixed?

Frame is a Quick Pro AR: One (non UDH)

Puncture

"Hey everyone,

So, I was out riding my gravel bike in the woods today and instead of just getting a regular puncture like a normal person—you know, plugging it, pumping it up, and moving on—I managed to pull a total 'pro move.' I ran over a 5cm long nail that went straight through my tire and punctured the actual rim bed (where the tubeless tape sits).

The hole is about 4mm wide, so it’s smaller than a standard spoke hole. I’ve already lightly cleaned it up with a Dremel to stop any carbon fibers from fraying. How big of a problem is this? Is it still safe to ride? I know rim beds have factory-drilled holes for nipples, but those are engineered, not jagged punctures from a nail. My plan is to fill the hole with some two-component epoxy, sand it flush, and re-tape it for tubeless.

Is this a solid fix, or is the rim structurally compromised? Thanks for any advice!"

Stopped during a ride to grab a bottle and adjust my helmet, accidentally clipped a foot back into the pedal, lost my balance and took a tumble. Noticed this damage on the top tube after my getting home from my ride.

What's going on with these Dura-Ace rims?

I bought a second-hand wheelset, and the seller threw these in for free. However, the carbon rims look (and feel) flaky! Is this delamination? Some type of non-structural clear coat failure? Why did this happen? I don't intend to ride them, but I wonder what's going on, and if they should just go in the trash (sad).

Edit: Thanks everyone for the reassurance! I appreciate it

Had a small crash with most impact on the shifters. Took off my bar tape and shifters to check the carbon handlebar, and can see these indentations. Thoughts?

Thanks

Hey folks, my father gave me his bike and I have it on the trainer when moving it it rubbed against the bike - is this structural or just cosmetic?

Would you say it's structural or just clear coat?

Hey it's me again :)

https://www.reddit.com/r/bustedcarbon/comments/1qloday/just_discovered_this_on_my_stem_base/

I have discovered a fracture on my carbon handlebar (or stem to be more precise).

For the warranty claim, the manufacturer wants me to send the the handlebar for inspection, they say they never saw something like this.

Now my fear is that I will have to spend a lot of money on mechanic remove/install/bleed the handlebar and essentially the manufacturer will just tell me 'it's cosmetic, your problem'.. just wanted to hear your opinions here before I go for it
