Pietra means “rock”, and this bike is as strong as one. Made with True Temper OX platinum cro-moly steel, this bike is built to take a beating and last a lifetime. All Zinn hardtails are custom designed by Lennard Zinn to fit great and perform on the toughest trails. The Pietra is available as a single speed or with a Rohloff speedhub, and is called the Pietra SS. If you travel a lot, go for the Pietra World, which is outfitted with S&S couplers and makes traveling with your bike a breeze.
