Ergon SR3 Pro Carbon Road Saddle. Ergon's top of the line road saddle, the SR3 Pro Carbon packs an astounding amount of features into this paragon of lightness and ergonomic efficiency. High performance is synonymous these days with carbon fiber and the SR3 Pro Carbon Road features an ultra thin, flex optimized carbon shell plus carbon fiber rails that contribute to the saddle's minimal weight of 200 grams. Ergon's engineers have also done a masterful job in ensuring there's all the comfort you need for even the most extended stints in the saddle. There's an anatomically shaped surface with a pressure relief channel, flexible side wings, orthopedic EVA foam, plus an upward curve at the saddle's rear that enables the rider to press into it for added stability and maximum power transfer. Not missing out on any opportunity to achieve marginal gains for the rider, there's even a silicone coating on the nose to reduce friction. Additionally, the saddle comes in multiple widths that enable you to truly find a perfect fit that corresponds to the width of your sit bones. Riders with a sit bone width of 9 11cm should choose a small, a 11 13cm sit bone width is a size medium, while a sit bone width of 13 15cm corresponds to the large saddle. This version of the Ergon SR3 Pro Carbon Road Saddle features a black synthetic leather cover. It's also available in a white version item YS SR3CW.
