good morning colleagues I look for help!!! Yesterday we started the service of a supercaliber, when we got to the center it was time to remove the pressfit from the carbon frame. I asked the workshop manager for help and with the parktool and hammer I removed the side of the transmission. The next my partner. We hammer from the outside in. Here is the problem after the pressfitt came out I think my shop manager hammered without seating or fitting the tool well on the bearing or something like that I think and caused a detachment of the carbon fiber layer of the bottom bracket shell. It is only raised, do not know about cracks or blows to the carbon fiber, these are learning about the material. Help, is this a problem? The box is damaged?

Sounds like your manager permanently damaged the frame if carbon is now loose.

10 mm gets the job done, like a .40 on steroids, but a box can be pricey...

Take/send the frame to a carbon repair specialist.

It sounds like this is a customer's bike damaged while in the shop. If the frame was damaged by an error by a shop employee working on the bike, the customer is owed a new frame.

Probably, but a skilled carbon technician should be able to tell for sure. It might just be superficial and a dab of epoxy will make it right, it might be that the frame was out of spec or there was a fault in the lay-up. It would be easy to blame the mechanic when the problem may not be entirely down to him.

No, actually if it can be proven that the shop damaged the frame, the customer is owed fair market value on the used frame. There is no specific performance on bikes in most states, but it sounds like the OP is elsewhere, so the laws there may vary.
