Am mid way through changing the bearings on a 2015 carbon scalpel. I’ve done the top two sets of bearings but can’t figure out how to remove the bottom pair (near the crank). I’ve smacked it hard with a mallet and an 8mm drift but it doesn’t seem to move. I dare not smack it any harder. Has anyone any idea? I’ve read the manual and I’m sure i’m doing it right but it’s just spreading the carbon linkage which will only damage it.

ta.
