Saddle Selle Italia WATT 3D KIT Carbonio Superflow with Carbon Rail +10mm (NEW)

The Selle Italia WATT 3D KIT Carbonio Superflow with Carbon Rail +10mm is a road and time-trial saddle engineered for aggressive rider positions and sustained efforts. The saddle features a wide Superflow central cutout that reduces perineal pressure and enhances blood flow, combined with a 3D-shaped shell that balances support and flexibility. Supplied in the KIT Carbonio configuration, the saddle uses carbon rails and a +10 mm offset to position the rider slightly rearward for optimized pedaling dynamics and aerodynamic posture.

Advantages

The wide Superflow cutout provides targeted pressure relief in the central area while preserving a continuous support platform for sit bones. The 3D-formed shell adapts to dynamic loads, offering consistent comfort during long rides and time-trial efforts. Carbon rails reduce weight and increase stiffness for efficient power transfer, and the +10 mm offset helps fine-tune rider position relative to the bottom bracket for improved aerodynamics and leg extension.

Suitable for

• Road racing where aerodynamic position and pedaling efficiency are priorities
• Time-trial and triathlon events requiring sustained forward-leaning posture
• Long endurance rides where pressure relief and sit bone support are necessary
• Aggressive or performance-oriented bike fits that need a slightly rearward saddle position

Key specifications

• Profile: 3D-shaped shell designed for a balance of support and flexibility
• Central relief: Wide Superflow cutout to reduce perineal pressure
• Rail material: Carbon rails for low weight and increased stiffness
• Offset: +10 mm rearward saddle positioning
• Application: Road and time-trial use, compatible with performance bike setups

How to use

Mount the saddle using a compatible seatpost clamp that supports carbon rails, ensuring manufacturer-specified torque values are observed to avoid damage. Use the +10 mm offset to adjust fore-aft position so that knee and pedal alignment suit your riding geometry; small incremental changes are advised and should be tested on short rides before long efforts. Periodically inspect the carbon rails and shell for signs of wear, cracks, or damage and follow the saddle care instructions from the bicycle and component manufacturers.

Usage recommendations

For best results, pair the saddle with a properly fitted bike position and padded cycling shorts. Start with conservative fore-aft adjustments and increase rearward offset only after confirming comfort and pedaling efficiency during test rides. Avoid overtightening the seatpost clamp and follow carbon-rail handling guidelines to maintain structural integrity.
