Of the S11 changes, the addition of the rollBar suspension system, adapted from the Racing Series S9, is the most impactful. The new construction increases vertical stabilization and allows a less restrictive waist construction. Coverage across the stomach and lower back also increased, providing more supportive, breathable comfort around the waist while accommodating aggressive riding positions. The butterfly-wrap paneling returns for S11, enveloping your muscles in micro-adjusted, fatigue-reducing compression that balances long-distance comfort with competitive aerodynamics. Updated for S11, the latest GTS insert radically increases cooling airflow, and the dual-layer 13mm construction adds 4mm of targeted support to the 9mm base of microshock-absorbing foam.
