Product Description Specialized Roubaix Pro 28" tyre - fast, cushioning, grippy The Roubaix Pro Road folding tyre from Specialized is a fast, high-traction all-rounder with the GRIPTON® compound. Compared to the Roubaix Armadillo Elite, its puncture protection is slightly lighter, but still proves to be efficient on poorly paved roads. Also helpful on this type of surface are the damping properties resulting from the wider tyre cross-section.

It was designed to filter out low and high frequencies.

It also dampens vibrations, rolls very well and saves weight. GRIPTON tyres are manufactured and tested in a factory operated by Specialized in Vietnam.
