Possible crack in carbon frame????

Hi everyone. I have an On One carbon 456. It has a mix taper headtube meaning that I had to get a hope pick and mix headset. I have ordered the correct cups from different websites and the bottom one has arrived and I installed it with a makeshift headset press (a long threaded rod, 2 nuts and 2 big washers) to start with and then two bits of wood and a g-clamp once it was in, to get it in properly. I have just found a small 10mm long crack in the paintwork which starts about a 1mm away from where the installed cup is. I was wondering whether people think it's possible to crack the carbon part on the outside of the frame by installing a headset cup, given that there are aluminium/steel inserts which actually make contact with the cup rather than carbon. The carbon just covers up the inserts. ...Or whether it's probably just a crack in the paint. The cup was fairly wonky at one point.

Very hard to tell - if possible, you need to get a shot in better light, as close as you can, then send to onone.
This is a crack in my frame, this measures less than an inch, the camera brings it out beautifully:0 -
Is it likely that it's a crack in the carbon as well as the paint?Delete my fucking account.0

Same position I am in ;-) Frame is going back to GT, just can't tell!0

Sorry about all the questions, but would it be a stupid idea to finish building it, ride it down some dodgy tracks and see if it gets any bigger? And if it doesn't get any bigger is that a guarantee that it's just a paint crack or could it still be a crack in the frame which just happened to stay the same after a ride?Delete my fucking account.0

Yep, not a good idea, quick way to kill off any warranty (never assume the manufacturers don't read this!)0

jusrt out of interest....would On-One warrenty the frame if the damage was created by a "bikeshop" installing the headset...they could come back saying they weren't to blame ?
Correct me if Im wrong but isn;t the only way of properly checking the frame is with an X-ray which costs the earth (unless you know someone in a hospital !)
sorry sounding all negative I know....just wondered myself tbh !
could you simply have nicked it when you installed the cup ?0 -
Many manufacturers have such machines, or composite experts.
If the store caused the damage then they are liable!0
