What are inexpensive ways to drop the weight of my Emonda ALR

My Current Emonda ALR weighs in at around 22 lbs with all components and the saddlebag and accessories. She largely comes with the stock components (wheels are stock alloy) and parts like stem, seatpost, saddle are all stock. The only non stock are the tires, one Pirelli Centroveli Velo and the other being a Specialized 30c.
