Made in Italy by Selle Italia, but designed by Colnago. The Nekkar's comfort starts with a 143mm width for a little more support over the typical 130mm-wide options. Selle Italia also uses a descent amount of padding with some cushioning to it which absorbs road vibration. Manganese rails are the standard round 7mm so this saddle will work with virtually all seat post clamps. The ubiquitous hole in the saddle adds comfort by reducing stress.
