611 Ergowave Active S-Tube 2.1 Saddle

What Our Gearhead® Experts Are Saying:

"I suggest this saddle for riders who want ergonomic pressure relief plus dynamic movement. The Active system noticeably reduces sit bone pressure on rough terrain, and the stepped design keeps you planted when putting down power on climbs."

The 611 Ergowave Active S-Tube 2.1 Saddle is engineered for high-performance off-road applications, delivering a precise balance of support, pressure relief, and controlled mobility. Developed specifically for all-mountain and enduro use, the Ergowave stepped profile features a raised rear section that stabilizes the pelvis and enhances rearward support under load. This structured saddle pocket promotes efficient power transfer by anchoring the rider during seated climbing efforts.

A lowered saddle nose combined with a pronounced central dip achieves 60% perineal relief, reducing pressure in sensitive areas while maintaining a broad contact surface. Compared to the 612, the 611 features a nose approximately 4mm wider, improving support on steep technical climbs without compromising pedaling efficiency. The flat profile maximizes usable surface area while minimizing unwanted pressure peaks.

Superlight foam padding is tuned with additional damping characteristics to absorb trail vibration and impacts. High-wear areas are reinforced with Kevlar material for increased durability in aggressive riding environments. The Active technology platform incorporates three interchangeable elastomer dampers, allowing controlled lateral movement that mirrors natural pelvic motion during pedaling. This dynamic function helps mobilize the spine and reduce sit bone pressure over extended efforts.

With Ti S-Tube alloy rails, a 275mm length, and multiple width options for precise sit bone matching, the 611 Ergowave Active S-Tube 2.1 is optimized for riders seeking biomechanical efficiency and long-distance comfort in demanding off-road conditions.
