Extremely easy to set up with single bolt. Only issue is on bumpy roads bumps the saddle would tilt and come out of adjustment even when tightened to recommended torque setting. Fixed using blue locktite on bolt / threads. A little disappointing and annoying.
Requires high torque on the single bolt to work. The lower clamp area is cheap plastic and does not want to rotate. It sticks in place and gets misaligned with the upper clamp area and this caused my saddle to warp. The saddle nose got twisted sideways. Wouldn't recommend due to cheap material used for clamping to saddle rails.
