This is top-of-the-line performance saddle and a popular choice for triathletes and time trialers. Originally designed for more aggressive riding in the 0* to 30* hip angle position (aerobars). The seat offers superb comfort in this normally uncomfortable position. The saddle is completely UCI compliant for those roadies. It even sports a nifty transition rack hook on the back for racking your bike. Uses light weight foam and gel pads with titanium alloy rails. 245mm long and 130mm wide.
