suspension seat post

feel it working on larger bumps if you dare sit through larger bumps,need to soften rebound for smoother surfaces then certainly helps the comfort of ride.I had ordered the post but came without the required shim so contacted Surface and they shot me one out asap. Happy with Surface and love the Rook bike.
