Superflow Technology

Selle Italia’s Superflow design features a generous central cut-out that relieves pressure where it matters most. By spreading your weight more evenly, it helps you stay comfortable and efficient on longer rides.

Boost Design

The short-nose Boost shape supports an aggressive riding position while giving you more freedom to move. Balancing stability with pedalling efficiency, it provides the support you need whether you’re pushing the pace or putting in long hours in the saddle.

Carbon Rails & Construction

Carbon rails offer an exceptional strength-to-weight ratio, cutting saddle weight without losing structural support. Paired with a durable Fibra-Tek cover, they create a premium build that stays responsive under power and holds up to the miles.
