What Is It?
The Selle Italia SLR Boost Endurance SF L TI316 is a premium endurance road/gravel saddle designed for long-distance comfort while keeping a race-oriented short-nose shape.
It’s part of the SLR Boost family, but tuned specifically for long rides, with:
- extra comfort padding (Light Gel Plus)
- a large Superflow cut-out
- a short nose for reduced perineal pressure
The “L TI316” version typically refers to:
- L = wider 145mm width (L3 fit)
- TI316 = titanium alloy rails (light + strong)
Key Features
-
Superflow central cut-out → reduces pressure on soft tissue
-
Light Gel Plus padding → added comfort for long hours in saddle
-
Short-nose “Boost” design → better aero position + reduced pressure
-
TI316 rails → strong, corrosion-resistant, relatively lightweight
-
Fibra-Tek cover → durable, sweat-resistant surface
- Endurance-tuned shape for long-distance riding stability
