So, I needed to slide my seat back, but wanted to keep the height and change the angle to protect my crotch. It was uncomfortable, as I am 6'2" and thin. I realized that you can put a washer between the frame and seat post before tightening the single upper seat bolt. This pivots the front of the seat rail down, raising the saddle and tilting it slightly. I used an automotive drain plug fiber washer for a shim, but any nylon or steel washer will do. A small shim goes a long way. Tilting the saddle forward a bit saves my family jewels from being crushed!
