  1. Charles F

    Comfortable, but not sure how to adjust the angle, please post the detail instruction online.

    • Serfas

      Hi Charles, The saddle angle adjustment process may vary slightly depending on your particular saddle mount, but for most saddle mounts one or two hex bolts are loosened and the fore/aft position and angle is adjusted while the saddle is situated within the loosened saddle mount. When your preferred positional adjustments have been made the bolts may then be re-tightened to spec to lock the saddle’s angle and position. Hope this helps! If you have any more questions please feel free to reach out to our Warranty department for further assistance. Email: / Phone: 623.888.5841 – The Serfas Team
