This top-of-the-range model features a sole that provides even greater foot support, ensuring an excellent fit and stability through numerous high-quality technical details. The upper is made of microfiber and mesh and, thanks to its special treatment, is breathable and dirt-resistant. The closure system offers precise adjustment and can be partially replaced if needed.

The lightweight, high-performance sole is made of nylon with PU (polyurethane) inserts. Its tread pattern is specially designed for mountain biking, providing good grip, helping shed mud and ensuring stability. The central insert with the Sidi logo acts as an anti-slip feature and is practical, especially for less experienced users. The toe area, which is more prone to wear, can be replaced using screws and also allows studs to be fitted to improve grip on particularly muddy terrain. The RS17 delivers the ultimate in sole stiffness and power transfer while riding.

SIDI’s TECHNO-3 system adjusts the upper to the shape of the foot for a customized fit. Like most small SIDI details, the TECHNO-3 BUCKLE is functional and replaceable.

The anatomical shape ensures optimal adjustment and even pressure distribution across the foot. It can be adjusted on both sides using the TECNO-3 rotary closure.

MICROTECH combines durability, stability, reduced weight and water resistance. It is made using the “Water-Tech” process. Its reduced environmental impact, lower harmful emissions into the air and workplace, and use of water-based products instead of solvents benefit both the environment and the end user.
