So, I stripped down the bike I bought recently (a Planet X carbon framed one) and found the headset rusty, the fork crown race cracked, and more importantly for this question the seats in the frame somewhat corroded - this is an integrated headset. Now I've replaced races in steel frames, drifting out the old and pressing in the new (and yes, I appreciate that in this frame they aren't races, just seats for the sealed bearings of the headset to sit in / be aligned by) but can I do the same for the seat in a carbon frame? Has anyone done this here? They appear just to be a press fit, and to function they don't need to be bonded in...
