eeSilk+ Elastomers

My seat comes loose. A friend of mine told me I am missing the thumb tightening gadget for the front bolt. It did not come with my seat post. Please send me one

Purchased this for my gravel bike but the motion moves me too far rearward which I don't like. Turns out that I can get just as much comfort out if mt RDI carbon seatpost and Ergon SMC core saddle and save weight too...

Even at tightened specs seat manages to to make a loud "click" sound and then will tilt downward at the nose of saddle while on rocky downhills. I have the rails set perfectly in middle so I feel this is due to a bad clamping design. Very disappointed. I am someone that owns multiple 110 headsets, eeSilk stem/bar, and another thudbuster (lt)...
