The Prologo Dimension Space Tirox 153mm Road Saddle is designed to fit riders that need semi-round or round shape, with “medium – low pelvic rotation/flexibility “and wider ischial bones distance. The Special Channel “PAS “ (wider and deeper) eliminates numbness and reduces the compression of soft issues, improving blood flow in the pelvic area. The extra 7 mm padding with special foam density and the 153 mm width of the saddle (compared to the regular version), ensure better comfort for longer rides or “to enjoy the daily rides”. Prologo has created this product for all women and men with a greater distance between the ischial bones that therefore require a wider saddle.  Prologo Dimension Space Tirox 153mm Road Saddle Features Designed to fit riders that need semi-round or round shape, with “medium – low pelvic rotation/flexibility  Soft microfiber cover Rail: Triox 7mm Size: 245x153mm Weight: 202g
