A year after winning a Eurobike design award for its innovative road/cyclocross suspension seatpost, Ergon has expanded the line to include a setback version. The new CF3 Pro Carbon Setback seatpost has 25mm of setback, which can be reduced to 13mm by flipping the FlipHead.
Like its predecessor, the new post uses a twin carbon fiber leaf spring design with ball bearing equipped pivots that allow parallel suspension movement, which help take the sting out of ultra-stiff road frames and road buzz and vibration.
The post is designed to allow your saddle to move backwards in an arc motion, while the carbon suspension beams equipped with pivots ensure your saddle remains horizontal and thus does not effect pedaling position. It is only activated on impact and otherwise remains static.
When a bump comes through your bike frame and pushes the bike upwards, the seatpost flexes in the opposite direction, neutralizing the bump. Otherwise, the post maintains direct road bike feel, though the Ergon VCLS flat springs do remain sensitive to small variations in road surface.
The new post is maintenance free, offers simple setback and saddle angle adjustment, weighs in at about 220 grams, and only comes in 27.2mm diameter. MSRP is $300.
And for whatever it’s worth, Ergon sponsored athlete and all-around good guy Dave Wiens was milling around the Ergon booth while we were getting the download on this new seatpost. The multi-time Leadville 100 winner says he’s a big fan of the post, especially when he heads out on gravel road rides around his hometown of Gunnison, Colorado.
