## Description

Review: Es una forma bastante sencilla de instalar un droper en la bici. Lo he utilizado un par de veces y es funcional, aunque para accionar la palanca debes ir muy lento o detenerte por completo. Es un recurso muy útil, sin embargo tiene desventajas al no tener mando en el manubrio. Si buscas agilidad no es la mejor opción pero si tienes tiempo de hacer detenerte para subir o bajar el sillín, entonces es perfecto
Review: Seat post works great for an 85 lbs child. The item shipped without a required set screw for the piece to attach the control cable to the seat post, but we were able to make do. Otherwise, works as advertised.
