Created for those who turn endurance into a lifestyle, the Selle Italia SLR Boost Endurance Superflow is the definitive short-nose saddle designed for long-distance performance. Born from the evolution of the iconic SLR family, this saddle takes everything that long-distance riders demand—comfort, stability, and freedom—and distills it into a compact, lightweight design fine-tuned for the most demanding rides.
Whether you're logging ultra-endurance miles, racing across remote terrain, or pushing your limits on epic weekend tours, the SLR Boost Endurance Superflow has been engineered to support you from start to finish.
A Short-Nose Saddle for the Long Haul
The SLR Boost Endurance is a short-nose saddle—just 248 mm in length—which allows for a more aggressive yet sustainable riding posture. This compact shape facilitates easier pelvic rotation and a more aerodynamic torso position, all while reducing pressure on sensitive areas. It’s a saddle that doesn’t just follow modern geometry—it leads it.
Light Gel Plus Padding — Endurance, Reinvented
What truly sets this model apart from the standard SLR Boost is its Light Gel Plus padding, strategically distributed to cushion high-pressure zones and provide sustained comfort over long distances. Unlike bulky gel saddles, Light Gel Plus maintains a slim performance profile while absorbing road buzz, trail chatter, and prolonged vibration.
This refined padding system allows you to maintain peak output while minimizing fatigue and discomfort—mile after mile.
Superflow Cutout — Total Pressure Relief
The signature Superflow technology is central to this saddle’s ergonomic DNA. Running deep through the center, the Superflow cutout relieves pressure on the perineal area, encouraging optimal blood circulation and reducing numbness on prolonged rides. It’s a must-have for riders prone to discomfort, and a game-changer for anyone riding in an aggressive position for hours at a time.
Titanium Strength, Featherweight Feel
Built with robust TI 316 tubular rails (Ø7 mm), the saddle achieves an exceptional balance between lightweight performance and shock-absorbing durability. The rails provide up to 25% more resistance to fatigue and vibration compared to traditional alloys while shedding unnecessary grams—making this saddle race-ready and adventure-capable.
With a total weight of just 202 g (Small) and 207 g (Large), it ensures no excess baggage holds you back.
Anatomically Tuned Sizing
Small: 130 x 248 mm – ideal for narrower sit bones and aggressive riding positions
Large: 145 x 248 mm – offers additional support and surface area for broader sit bones
This tailored sizing, coupled with the IDMATCH system, ensures every rider finds the perfect fit for maximum comfort and performance.
Ride Beyond Limits
From ultra-endurance road riders to gravel adventurers and Ironman competitors, the SLR Boost Endurance Superflow is engineered to go further. With a waved rear profile for sit bone support, a shortened nose for better maneuverability, and premium comfort technologies woven into its compact build, it is the go-to choice for serious cyclists who need a saddle that can match their ambition.
