I would do to the cypress what I have done to my Sedona.

1) Change to better tires.

2) Add bar ends

3) Replace the suspension fork with a rigid. I did it partly for weight, partly for handling. I didn't notice the weight savings, I did notice the handling.

My next change will probably be the seat post, as I have tightened mine so it doesn't move, and it works well for me, therefore, I save weight inexpensively without sacrificing comfort.
