Very strange won’t come off, they are basically Shimano cranks from Acoustic bike. Check bolts loosened & tab removed then may need tapping on back of crank arm with rubber mallet
I ordered few bits last week saying still processing 1 item missing/ out of stock which have been refunded for & managed to get through on chat but think large volume orders means being slow
DSD runt with Novy Splug in a Yari makes for a good fork but thinking of swapping back to my Mezzer Pro as love that fork & bit stiffer fork. It’s on an Orbea Rise
