Perfect choice for endurance and long-distance cyclists, the saddle adds an extra gel layer to the flat seat, providing a platform of stability and performance. Its long-lasting Fibra-Tek finish is built to last, and the Superflow cut-out relieves pressure on the perineum. The saddle of choice for Pantani, Ewan, and van der Poel just got even better. The Boost short nose improves thigh clearance and saddle fit while reducing weight, and the flat shape offers a classic feel. The source also describes a variant with no cutout, while titanium rails and a Fibra-Tek cover are stated to provide durability and weight savings.
