S-Tube is a proprietary alloy that includes titanium but is stronger and lighter.
This is top of the line of SQlab MTB saddles.
The 611 active MTB saddle features a longer, down-curved nose that gives technical riders additional seating positions for cornering and steep climbing.
The saddle body features carbon fiber reinforced plastic with optimized wall thicknesses, Titanium Alloy rails, and is covered with SQlab's tough yet breathable K18 material with Kevlar reinforcement at the nose and wings of the saddle for crash protection.
The exclusive active System, T-Beam allows the saddle to rock slightly with the hips when pedaling.
This dampened lateral tilt allows the saddle body to follow the biomechanical movement of the pelvis on each pedal stroke.
The result is a decrease of pressure on the sitbones and a mobilization of the spinal discs.
Additionally, SQlab's Stepped Design offers more support to the back which improves the biomechanical pedaling efficiency and a Pressure Free Zone to relieve pressure on the sensitive genital and perineal areas.
More freedom, lesser pressure with the SQlab Stepsaddle Concept!
The lowered saddle nose of SQlab's stepsaddle design was developed by SQlab's head of R&D Dr. Stefan Staudte (Urologist & Extrembiker) to distribute the bodyweight by medical view points.
