Vertigo Nack

• Speed and innovation: The Vertigo Nack, Prologo’s flagship Mountain Bike saddle, combines technologically sophisticated construction with mountain bike specific design.

• Rounded domed profile creates a cantered platform for the sits bones while supporting the muscles of the gluteus and hamstrings. Slightly raised tail-end adds leverage during fire-road climes.

• Super Light Foam upper designed with a narrow recess channel to reduce perineal zone pressure, as well as extra padding in the nose for added comfort during rocky sections or very steep seated climbing.

• High Weave Density (HWD) base tunes the ride quality of the Vertigo Nack for light weight, strength, and support. Prologo’s proprietary HWD base is constructed of different carbon layers and resins, resulting in a base whose varying thickness, density, and elasticity compliment the Super Light Foam upper.

• Braided Cord Rail (BCR) is Prologo’s exclusive saddle rail design. Constructed of braided filaments of carbon and Kevlar reinforced with aluminum filaments in the clamp area, the BCR achieves extreme light weight without sacrificing durability.
