SANDBLOCK® is Marwi’s own developed and patented non-slip compound. The compound is a high-quality non-slip surface providing excellent grip in all weather conditions. Due to the material composition, SANDBLOCK® is wear- and water-resistant and bonded with a pedal body using a specially developed glue that is being applied fully automatically by a robot. This creates a tight bond that ensures that the SANDBLOCK® material cannot be peeled off the pedal body. Due to all these pro’s, the SANDBLOCK® material outperforms ‘sandpaper’ and ‘grip-tape’ pedals by a mile.
