ISM road saddles basically give you carte blanc to roll as far forward as your shoulder, neck, and eye muscles will allow you to.
It comes at the cost of needing to be set up just right and being choosy when it comes to chamois pads. A few MM to high will give you saddle soreness quickly, as will a few tenths of a degree of tilt.
I’m still not 100% sure about fore and aft… Any suggestions? Haha.
The lack of a nose does take a bit getting used to while riding quickly downhill.
