What is this small damage on my top tube?

Post image
3 Upvotes

I just got my first carbon bike recently. There is a small paint chip at the end of a longish indent. I didn’t crash. You can feel it easily with your nail.

Does that compromise the carbon’s integrity? Or just a scratch and safe to ride?

Thanks very much to this community in advance!

Should I be worried or is this just the clear coat?

Passes tap test and cracks seem to just be on the top but I’d like to get a couple more opinions.

Cracked frame or just the paint?

2 Upvotes

I have this Carbon Specialized Hardtail and noticed a crack in the paint, under the seatpost. Is it only the paint or is the frame damaged? 

Are there ways to test it? I cleaned it because I wanted to sell the bike, but now noticed this.

Hit some loose gravel today and pinged some rocks off my frame. Anything to be concerned about?

Tarmac SL6 Dropout Damage

Took my wheel out because of a flat and noticed what seems to be a crack in my dropout of my Tarmac Sl6 Disc. Not sure how long this has been here, but I'm now concerned about it failing. The carbon does not flake or flex when squeezed. What's the best course of action?

Safe to ride? Concern about possible crack on used carbon frame

Hi everyone, just bought a used frameset (2010 Ghost AMR Lector Plus 7700) which was a bike I really liked back in the day. It wasn’t exactly cheap, but I was excited to get it.

After a closer inspection at home, I noticed something around the bottom bracket area (pics attached). I’m not sure if this is just paint chipping or if it’s a crack in the frame.

Should I be worried?

Visual inspection after a crash

Crash destroyed one of the shifters and the other clearly took a big impact to. Removing the shifters and visually inspecting the carbon handlebar and I can see marks and delamination where the metal bands were. I can’t hear any creaking under my weight but the marks look bad.

Are my handlebars borked?

Busted drop out?

1 Upvotes

I crashed in a roundabout and slid on the non drive side of my bike. My bars are unfortunately busted, but I am wondering how you would assess the damage on the drop outs? Your thoughts and expertise is very welcomed. Thank you!

Chain fell off without noticing and I gave the pedal a good kick because I was crossing a big busy road. Chain got stuck in the frame I had to open it before I could remove it. Any thoughts?

60mm rim brake tubular wheel from Facebook marketplace served me well. I think I was third owner. First carbon wheels. There was a small chip I noticed shortly after I got ‘em, hit a few bad potholes and a crash on one of my last rides and it turned to this. On the brake surface no less. RIP, served me well for about 2000 kM. New wheels out of storage and installed already 😅 I missed during the buying process, inspect carefully friends

So i dropped my chain on a ride today while shifting to the big chainring. I did the coin test and the sound was noticably duller when tapping directly on the deeper left scratch. Should I be worried?

Already posted in r/bikewrench but got deleted after awhile. Just wanted to get more opinions.

Does that bubbly thing on my fork looks like a void or is it a bad paint job? I was literally able to peel off that paint over that veiny thing. Bike is almost brand new.

Concern about carbon fork on my Focus Mares (2010)

Thumbnail

2 Upvotes

Hello everybody,
I have a Focus Mares Cyclocrosser (aluminum frame, carbon fork, rim brakes, Froglegs) from around 2010.

I replaced everything that needed replacing, and I’ve done a few hundred kilometers on it. It rides super nicely — I really like it.

But now I’m a bit worried about the fork.
There are some chips in the paint. They were filled with paint, but I don’t know how the damage happened.
What I do know: the bike was ridden very hard before I got it. All the parts were worn out, and it was super dirty when I got it.

Should I replace the fork?
Writing this out, I’m starting to think: yes?

Thanks for any advice!

Paint damage?

Thinking that this might be cosmetic paint damage, and possibly due to flexing where the dropout joins the fork?

The fork/dropout is completely fine on the other side.

Thanks

I discovered this after a ride. Something hit that spot from the tire. I have requested quotes, but in the meantime: is this safe to ride?
