JRC Kokoro Carbon Seatpost 27.2 mm
Through rigorous design and testing, we bring to you one of the very best seatposts in the world. Our goal was to produce a durable, ultra-lightweight seatpost without the extortionate price tag seen on almost every other seatpost of similar specification. Our results were striking; concluding with total weight from as little as a mere 103grams (250mm* 27,2mm).
Our Kokoro seatpost features varying wall density enabling us to lessen the layers of carbon in areas of low stress levels while ensuringmaximum durability through increased wall thickness in areas of higher stress. The intricate tube design enables us to manufacture carbon tubes up to 50% lighter than most competitors without any compromise in strength or stiffness levels.
When seated,weight distribution on the front and the rear of a seatpost is unequal and bearing this consideration in mind we also took the time to test loads. The results meant we opted for slightly thicker walls on the front of the cradle and the frontal yoke.
