Lol at that. No you are not torquing your frame that much unless you are literally a bull, rhino, or silverback gorilla. Even then the frame would break before it could flex that much.

Sometimes the best way to find the problem in this situation is to borrow things from friends. Borrow a chain and see if you can jump the chain. If it still jump, borrow a chain ring. If it still jumps, borrow a cog. One of those parts has to be he problem.
