The Zero TRI PAS saddle is designed by Prologo especially for the use in triathlon. The flat shape is suitable for medium-short distances. The big cut-out extends the entire length of the saddle relieving the peak of pressure in the perineal area.
The DELTA standard requires a rotational movement of the foot toward the outside or inside for disengagement. This function improves the cyclist's safety; no body or bearing prevents disengagement toward the inside.
