i posted this over in the MTB forum but realized it's not so much about mountain bikes as it is about carbon frames in general. i've got a carbon frame on the way to me, and while i've dealt with plenty of carbon on road bikes i've not dealt with a carbon frame for a MTB.
this frame has a press fit bb. i'm also going to install an angleset.
with aluminum, i'd make sure the bb cups and headset cups had a healthy amount of grease. is there any difference in pressing these cups into a carbon frame vs aluminum?
on my road bikes due to the particular bbs and headsets, i've not had to press them into the frame.
