Bicycle saddle Selle Italia ST 3 SuperFlow — cross-country unisex, seat width 16 cm, depth 27 cm, 406 g

The Selle Italia ST 3 SuperFlow is a cross-country unisex bicycle saddle designed to reduce perineal pressure and provide sustained comfort during off-road and endurance rides. Featuring a central SuperFlow relief channel and gel-enhanced padding, the saddle balances anatomical support with shock absorption. With a 16 cm seat width, 27 cm depth and a weight of 406 g, it pairs alloy rails with a Soft-Tek cover and reflective Hi-Viz rear inserts for nighttime visibility.

Advantages

The SuperFlow central cut-out reduces pressure on soft tissues and improves ventilation, while the gel insert within the padding increases comfort on longer rides. The 16 cm width and 27 cm length offer a medium platform suitable for varied riding positions typical in cross-country cycling. Alloy rails provide a balance between lightness and durability, and the Soft-Tek surface offers a grippy but comfortable contact area. Reflective Hi-Viz elements enhance visibility in low-light conditions.

Suitable for

• Cross-country and off-road cyclists seeking pressure relief and comfort
• Unisex riders who prefer an anatomical saddle with a central relief channel
• Endurance and gravel riding where longer time in the saddle is expected
• Riders wanting a medium-width saddle (16 cm) with moderate cushioning

When it may not be suitable

The ST 3 SuperFlow may not be ideal for riders who require a wider or narrower platform than 16 cm for correct sit-bone support; an incorrect width can reduce comfort and performance. It may also be less suitable for racers seeking an ultra-light race-specific saddle, as its gel padding and alloy rails prioritize comfort over minimal weight.

Key specifications

• Saddle type: cross-country / unisex with anatomical relief channel
• Width: 16 cm
• Length (depth): 27 cm
• Weight: 406 g
• Padding: gel insert for improved shock absorption
• Cover material: Soft-Tek
• Rails: alloy (7x9 mm profile)
• Visibility: Hi-Viz reflective inserts on the rear

How to use

Mount the Selle Italia ST 3 SuperFlow according to your seatpost manufacturer’s instructions, aligning the saddle so that its central relief channel follows the bike’s centerline. Adjust fore-aft position and tilt to achieve even sit-bone contact; a small nose-down tilt often reduces pressure on the perineal area. Check rail clamping torque to the seatpost and retighten after a short break-in ride. Regularly inspect the Soft-Tek cover and rails for wear and clean with mild soap and water.

What to consider before purchase

• Measure sit-bone width to confirm 16 cm is an appropriate size for your anatomy
• Decide if gel padding and a medium-weight saddle meet your comfort versus weight priorities
• Ensure compatibility of alloy rail dimensions with your seatpost clamp (7x9 mm profile)
• Consider intended riding style (cross-country, gravel, endurance) to match saddle shape and relief channel

Usage recommendations

For best results, pair the ST 3 SuperFlow with a properly fitted seatpost setup and spend a few short rides adjusting position. Use the central SuperFlow channel and gel padding to relieve pressure during longer efforts, and rely on the Hi-Viz rear inserts to increase visibility on low-light rides.
