hi there. i went riding today to delamere. on the jumps and dh runs the chain becomes loose and falls off and when you pedal again it goes back on the chainring but this gets kind of annoying. so i want to take off the big and granny ring and use a chainguide for the middle ring but my problem is i don't have iscg mounts on my frame.

is there such thing that you can put between the bb shell and bb so you can fit a chain guide?

and do i need new chainring bolts if i want to take off the big and granny ring so i can leave just the middle ring?
