Flite Boost Gravel Saddle w/Ti316 Rails

Selle Italia Flite Boost Gravel Saddle w/Ti316 Rails is a performance-oriented gravel saddle built around low weight, durable materials, and fit guidance that helps riders choose the right platform for long mixed-surface mileage. The combination of Ti316 hollow titanium 7mm rails and a Fibra-Tek cover targets reliable support with reduced weight compared to many steel-rail saddles, without sacrificing day-to-day durability.

Fit-focused highlights for gravel and endurance riders

1. Ti316 7mm hollow titanium rails - Balances strength and low weight for a responsive build without the fragility concerns of ultra-light rails
2. Standard 7mm round rail format - Broad seatpost compatibility for straightforward installation and easy swaps between bikes
3. Fibra-Tek cover - Hard-wearing outer material designed for durability and consistent feel in all-weather, high-mile use
4. Selle Italia idmatch sizing support - Uses rider fit inputs to narrow saddle selection and reduce guesswork when dialing in comfort
5. L3 / S3 fit codes - Helps match saddle shape/width guidance to rider anatomy; L3 is aimed at wider intertrochanteric distance, while S3 targets narrower intertrochanteric distance (both referenced for high pelvic rotation in Selle Italia’s idmatch system)

Note: The rail material on this listing is Ti316; Selle Italia also offers other rail materials (such as manganese) on select models/variants.
