Overview

The ENVE X Selle Italia SLR Boost 3D Superflow saddle combines Selle Italia’s flagship SLR Boost platform with ENVE’s innovative design. It features a 3D-printed cover made with Carbon DLS™ technology and Hi-Tech carbon rails, delivering a lightweight and supportive saddle optimized for road and gravel riding.

3D Printed Cover and Zonal Support

The saddle’s upper material uses a special polyurethane cover called Soft-Tek with custom perforations. The 3D-printed pattern incorporates differentiated cushioning zones that progressively absorb impact, providing support where needed and improving comfort during long rides.

Superflow Cut-Out and Neutral Shape

The large Superflow cut-out reduces pressure in the perineal area, enhancing rider comfort over extended periods. The saddle’s neutral anatomical shape supports both dynamic and static pelvic positions, accommodating a wide range of riders.

Rails, Fit, and Sizing

Available with carbon or titanium rails, the saddle uses 7×9 mm oval rails that are 10 mm longer than standard for increased adjustment range. Two widths are offered: 130 mm (S3) and 145 mm (L3), both with a length of 248 mm. The carbon rail version weighs approximately 130.5 g (130 mm) and 134 g (145 mm), while the titanium rail version weighs 161 g (130 mm) and 166 g (145 mm).
