Road Cycling“It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway
I've had really good luck with Zipp Service Course seatposts, both AL and CF. The 2 bolt top makes dialing in seat angle very accurate & I have never had one slip or loosen up. That is my go to post now on 4 bikes, I have a lot of confidence in it which is important.
