When something is "award-winning" our heads turn. When something wins an award at Eurobike, we take a closer look. Ergon's CF3 Pro Carbon Seatpost is a revolutionary design with head-turning aesthetics that aren't just for looks. It took over a year of legal logistics to import them into the US, but they are finally here.

The CF3 is specifically designed as a lightweight, yet stiff seatpost that works in tandem with today's ultra-stiff road frames. Viewed from the front, it looks like any other carbon seatpost. However, when you look at it from the side, it appears split into two pieces. This intriguing design is essentially two separate pieces of carbon fiber that are joined by the saddle clamp. They function as leaf springs to absorb road buzz and bumps. Because ultra-stiff carbon frames are not always the softest rides on rough roads, Ergon developed the CF3 Pro to interface between the rider and their bike.

The saddle rotates in an arc as it is moved fore and aft, yet the pivots at the head ensure that the saddle remains constantly level. Subsequently, making micro adjustments to your position is easier and you won't have to fight the seatpost clamp to keep your saddle level.

The CF3 Pro Carbon weighs in at 220grams. It has a 220lb rider limit and is not suggested for mountain bike use. It is 27.2mm by 330mm and comes in two seat clamp styles: One for 7 x 7mm round rails and one for 7 x 9.6mm oval rails.
