611 Ergowave Active S-Tube 2.1 Saddle

What Our Gearhead® Experts Are Saying:

"I recommend the 611 for riders who want aggressive off-road support without sacrificing comfort. The stepped Ergowave shape really locks you into position on steep climbs, and the active system takes the edge off chatter on rough terrain. It’s especially solid for long all-mountain days."

When the trail turns steep and technical, the 611 Ergowave Active S-Tube 2.1 Saddle from SQlab keeps us centered and supported. Purpose-built for all-mountain and enduro riding, it combines ergonomic shaping with trail-ready damping to help us stay powerful and comfortable through demanding terrain.

The wave-like profile and raised rear section provide defined support in the saddle pocket, stabilizing the pelvis for improved power transmission on climbs. A lowered nose and central dip relieve pressure in the perineal area, with a 60% relief design to reduce numbness over long rides. The nose is approximately 4mm wider than the 612 for enhanced support during steep, seated ascents while maintaining a flat profile for efficient pedaling.

Superlight foam padding is tuned for off-road use, offering more damping than road-focused models to smooth out trail chatter. Kevlar-reinforced zones protect high-wear areas, while SQlab’s Active technology allows controlled lateral movement via interchangeable elastomer dampers, supporting natural pelvic motion and reducing pressure on the sit bones. With Ti S-Tube alloy rails and multiple width options for precise sit bone fit, the 611 Ergowave Active 2.1 is engineered for riders pushing hard on rugged terrain.
