Magura distributes Syntace products in the US so all our test bikes were outfitted with them. The Syntace P6 carbon fiber seatpost was engineered using FEM as well as extreme runs on a testing machine to lead the way to a new and load-oriented material distribution. All parts of the head are cold-forged from 7075 aluminum to make; what independent testers have found to be, one of the strongest carbon posts on the market.
