SADDLE GUIDE 4ZA engineers and designer s are passionate cy clists. They know how important the support of the saddle is during long rides. Starting from scratch, our design team went back to the 3 basics of what makes a great saddle. The result is a focused line of seats providing the right solution for your specific body. Enough variations to find the right fit but not so many that you get overwhelmed by the decision process. – Eliminate Saddle Sores – Maintain Comfort in Multiple Seating Positions – Give Your Legs Freedom of Movement 4ZA SADDLE WIDTHS Due to the v ariation in a rider’ s weight and the distanc e between the sit-bones, 4ZA offers Men’s saddles in 2 widths (130mm and 145mm) in all our models ( Stratos, Cirrus and Cirrus Pro). The correct width of saddle f or one’s body type will result in a mor e efficient and c omfortable pedal str oke, while the wrong size can adversely affect the pedal stroke.
