Featuring titanium alloy rails with a chromium nitride (CrN) coating, you've got excellent tensile strength, rigidity and corrosion resistance, plus a very low weight. These high-quality rails also increase the durability of the saddle, as they are far less able to flex and creak as you're riding. The rail's strength and lack of bulk help you to save energy when conquering a long climb or putting in a big effort when accelerating up to top speed.
