well if you're not going to switch out your cog that often, would threadlocker (i.e. loctite) fix this? i recently did the same thing but i applied red loctite and it holds up to a small amount of hopping but i havent done any skidding because i was afriad that the red loctite isnt strong enough~ whats the torque in psi are our legs when we skid? (say 48x16 ratio)

let me know! <3
