Features - Sixpack EVO Rail Ultra Saddle

Ultra-lightweight construction

Exceptionally low weight combined with generous padding, for true comfort without the typical weight disadvantage. This is made possible by the patented one-piece construction made of fiber-reinforced polyamide, in which the shell and rail system are combined into a single, highly efficient unit. This saves weight, improves load distribution, and simultaneously ensures precisely tuned flex characteristics on rough terrain.

Ultra Comfortable E-TPU Padding

The generous E-TPU padding effectively absorbs shocks and distributes pressure evenly—for consistent comfort on rides of length and technicality. The textured Direct-Contact surface provides additional grip and delivers a stable, direct riding feel—especially noticeable on technical sections, climbs, and fast descents. The central relief channel supports balanced pressure distribution for a wide variety of riding positions and pelvic alignments. The EVO Rail Ultra always offers you the perfect seating feel, from an aggressive gravel position to an upright enduro geometry.

Ultra Easy Mounting System

The seatpost’s top clamp does not need to be completely removed. Simply loosen it, slide the saddle in, secure the position, and you’re done. Fast, clean, and straightforward. The minimalist interface is compatible with all top-clamp seatposts—no adapters or special parts required.

Bottom Mounting Point

The EVO Rail Ultra features an integrated M5 bottom mounting point beneath the saddle shell. This allows accessories to be attached directly to the saddle—clean, minimalist, and weight-optimized. Additionally, a specially designed saddle bag mount is available that attaches directly to the mounting point, allowing for the secure attachment of saddle bags. Ideal for gravel, bikepacking, and long trail rides.

Gravel

Ultra-lightweight yet very comfortable thanks to the generous padding. The unisex relief channel contributes to a stable and comfortable seating position in aggressive road and gravel riding positions. Ideal for long days on the saddle where comfort and efficiency are equally important.

Trail & Enduro

The textured E-TPU surface provides a direct contact feel and built-in grip—uphill and downhill. Lightweight and comfortable for long trail days, with padding that also supports the upright riding positions of modern trail and enduro geometries.

Gravity

The compact shape remains neutral even on the steepest descents and never gets in the way. As soon as the bicycle is actively steered, the textured surface provides precise control over the knees and thighs—direct, grippy, and controlled. Developed, tested, and refined under DH World Cup conditions.
