Make sure you aren't losing valuable seconds in a triathlon or time trial with a saddle that isn't designed for being used with your aerobar position. Profile Design's Vertex Saddle with Titanium Rails is part of a line created specifically for racing on a bike with TT or triathlon geometry. This saddle uses rails made with titanium to absorb road shock for a more comfortable ride, and it adds less weight to your frame while remaining just as strong compared to the Vertex Chromoly saddles in this line. Profile Design uses injected foam paired with a composite shell to create a shape that's most beneficial for riders stretched out over aerobars, and this model of the Vertex includes a cutout in the middle of the saddle to aid in pressure relief and ventilation. An anti slip microfiber cover is stretched over the shell to keep the saddle feeling smooth, not abrasive, against your skin, and the saddle's firmness ensures it will keep its shape and provide consistent support over its lifetime. Weighing in at around 285g, the Vertex Titanium includes a 7mm clamp zone.
