Does the job
"You know when the marketing rubbish says a frame is compliant, but the reality is it’s as stiff as a washboard. Well this seatpost is the answer. Smooths the ride out nicely. It’s not perfect. Muck and water gets between the leaves and causes noise. Needs regular cleaning if used on mucky gravel. You have to find somewhere else for a Di2 battery. And obviously there is no rebound damping, so if you take a big hit you do feel the kickback. But it does work in providing an effective plush ride to another wise uncompliant rear end."
