X-Bow Superflow Saddle w/ FeC Alloy Rails

Selle Italia X-Bow Superflow Saddle w/ FeC Alloy Rails is built for riders who want measurable pressure relief and calmer road feel without moving to an overly soft saddle. Its rear-set rail fixing and large SuperFlow central cut-out are designed to unload the perineal and sit-bone contact zone during long efforts, while an integrated damping interface between the shell and rails helps reduce transmitted vibration.

Key ride-facing advantages

• SuperFlow pressure-relief cut-out - Drastically reduces prolonged pressure in the perineal area to help maintain comfort and pedaling consistency on long rides
• Rear-positioned rail fixing - Frees up the main pressure zone under the ischial bones and perineum by relocating the rail attachment toward the back of the saddle
• Shell-to-rail absorption system - Helps reduce road shocks and high-frequency vibration for less fatigue on rough pavement, broken tarmac, and mixed surfaces
• FeC alloy rails - Carbon-iron steel alloy rails tuned for high strength with controlled flex for a supportive, durable ride feel
• Polyurethane cover - Delivers a stable, comfortable interface that stays consistent across long durations

Fit notes: L3 sizing targets riders with a “wide” intertrochanteric distance and high pelvic rotation; S3 targets a “narrow” intertrochanteric distance and high pelvic rotation.
