Five to ten grams of carbon that ends the rattle inside your Colnago Y1RS seatpost.
For Shimano Di2, a carbon fibre cover over a 3D-printed carbon composite body; for SRAM, a full-carbon holder at 5 grams. Both in a forged carbon or 3K weave finish. Ultralight, secure fit, no rattle — three claims, all of them the point.
