I don't have canyon cage (top block) but looking at the pictures from the "
show us your canyon cages" section,
that bolt head should be small enough to fit inside the tube end of the cage. Your picture looks like it's hitting
the tube instead of going in it. Did you mix them up? If not, the only thing I can think of is that you need to spin the bolt so
it's hex section inside the frame is fully seated in the frame (or engine or where ever it goes into).
I'm sure someone else with actual canyon cage experience will be along to help, but it
is Friday night, they may all be out and about.
