    1 pulley derailer

    I am just wondering is it work to use only 1 pulley(the upper one)?

    The purpose is to make the derailer shorter for clearance. I use the short cage already but just wondering if it would works.

    No, the lower pulley is needed to keep the chain tight.

    The trouble with common sense is it is no longer common
