Selle Italia SLR Boost Gravel TI316 Superflow L3 Saddle
The Selle Italia SLR Boost Gravel TI316 Superflow L3 is a premium performance saddle developed for gravel cyclists who demand long-distance comfort, efficient pedaling support, vibration control, and lightweight construction. Based on Selle Italia’s renowned SLR platform, this gravel-specific version combines a compact profile with advanced cushioning and shock-absorbing technologies designed for rough roads, mixed terrain, endurance events, and adventure cycling.
Compact 145 × 248 mm Performance Shape
The saddle features a modern 145 × 248 mm short-nose profile that provides a stable seating platform while allowing greater freedom of movement.
Its compact shape helps support an efficient riding position during:
Long gravel rides
Endurance events
Fast racing
Extended climbs
Technical mixed-terrain routes
Bikepacking adventures
The L3 width provides additional support for riders who benefit from a wider contact area.
Superflow Pressure Relief
At the center of the saddle is Selle Italia’s large Superflow cutout, designed to reduce pressure in the perineal area.
This central opening helps improve comfort during extended periods in the saddle and can reduce pressure-related discomfort when maintaining an aggressive or endurance-oriented riding position.
The Superflow design is especially beneficial during long rides where consistent pressure relief is important.
Light Gel Padding
The Light Gel cushioning layer adds targeted comfort without giving the saddle a bulky shape.
It helps absorb vibrations produced by:
Gravel roads
Broken tarmac
Washboard surfaces
Small impacts
Rough trails
This additional cushioning makes the SLR Boost Gravel particularly suitable for long-distance riding where repeated vibration can contribute to fatigue.
TI 316 Tubular Rails
The saddle uses TI 316 Tube Ø7 mm rails, offering a strong balance between low weight, durability, and vibration damping.
The titanium-alloy rail construction helps absorb road and trail feedback while maintaining the structural strength required for demanding gravel riding and competition.
Shock Absorber Technology
The integrated Shock Absorber system is positioned between the saddle shell and rails to further reduce vibrations and impacts transferred from the bike to the rider.
This technology helps improve comfort on uneven terrain and is particularly useful during:
Gravel racing
Long adventure rides
Rough country roads
Off-road endurance events
High-mileage training
Carbon Powered Shell
The Carbon Powered shell combines high-grade nylon polymer with carbon composite reinforcement.
This construction helps provide:
Excellent structural support
Reduced overall weight
Consistent flex characteristics
Responsive pedaling feel
Reliable long-term performance
The result is a performance-oriented shell that balances stiffness and controlled flexibility.
Fibra-Tek Cover
A premium Fibra-Tek microfiber cover provides durability while keeping the saddle lightweight.
The material is designed to resist regular wear from training, racing, and adventure riding while maintaining a clean, professional appearance.
Hi-Viz Reflective Detailing
The saddle includes Hi-Viz reflective elements that improve visibility in low-light situations.
This feature is useful during:
Early-morning rides
Evening cycling
Long-distance events
Bikepacking trips
Changing weather or lighting conditions
Neutral Anatomical Shape
The SLR Boost Gravel uses a Neutral shape, making it suitable for a broad range of riding styles and pelvic movement patterns.
It provides a versatile balance for riders who move dynamically on the saddle as well as cyclists who maintain a more stable seated position over long distances.
