This saddle was developed between Qu-Ax and Kris Holm and is based on Kris's Fusion saddles.
Besides a slightly modified shape (less wide in the middle), it also figures a "double-density foam" - which means the saddle has a softer density top layer and a fairly high density foam core in the middle of the saddle. The higher density core prevents the rider from sinking too far into the foam, makes the saddle curve gentler, and adds shock absorbency for harder impacts. Foam is trimmed tightly along the sides, particularly towards the front, to minimize chafing. The saddle cutaway is shaped to reduce center pressure.
Very durable cover in QX-design, compatible with T-bars, Shadow Base, Reinforcement-plates and KH handles.
