[Closed] Can you ream the bearing seat for a carbon frame with an internal headset?

not really

Why would you want to?

to fit an angle set or some such.

You can clean up the resin, I wouldnt want to cut into the carbon.

New Carbon frame and attempting to install a CK Dropset 2 and there's about a 1mm gap between the griplock assembly and the top of the headtube.

Just had a look around and there seems to be others with a similar problem.

Chris King spec normally spec the ream depth so you can check if it is compatible with your frame.

I'd check your frame is manufactured within spec/tolerance.
