Removed titanium bolt
Now crank seems stuck/frozen in place....without damaging anything is there a trick to Getting both crankarms loose

Pull harder. It’ll come apart

Yeah just try to pull evenly so you dont just pull on the arm as it will then possibly damage the bearings from the bending force.

Sometimes when they are really stuck i need to put both feet on the frame. One on chainstay and the other on downtube and pull with one hand on the crank arm and the other on the opposite side of the arm on the chainring.

Put the bolt back, turn it a couple of times, and then put something in the middle touching the bolt's head. Maybe a large allen tool or a wood stick, then tap the stick with a hammer.

I’ve had good luck rethreading the retaining bolt back in just a little bit, insert something to hit it with a hammer (piece of wood or socket set extension) to free it up and move it out a little. Then it’s easy.

Ultra types faster than I do.

Yes, soft tap with a rubber mallet or a 2x4 should do.

thread the middle bolt half way in and use a mallet to tap on the bolt.

+1 on rubber mallet.....actually bought one specifically to solve this very problem many years ago. good luck....it will come apart eventually!

Asked and answered BUT when you re-install, lotsa grease in those cups..even with SR/Record(Cult and USB bearings)..

OP here the trick of screwing in bolt a little and gentle rubber mallet tap worked!
