Selle San Marco Shortfit Carbon FX wide
"The SHORTFIT saddle was created to meet the needs of the most demanding cyclists. The special ergonomic shape of this saddle features reduced length and ensures proper support in the generous rear section and optimum pressure distribution in the front section.
The long central cutout (Open -Fit) guarantees all-day comfort and support on the whole length of the saddle. This feature improves the blood ﬂow preventing numbness and provides relief from pressure on the perineum."
