('dot Computer Optimized Measure') concept which allows for calibration of the size of the tread dots according to their position on the tread surface. The dots are smaller in the center, for less rolling resistance, and larger towards the sides, for better grip, creating a tire that is fast on the straightaways and safe in corners. It also contains their Aramid 3D compound for puncture protection as well as a more robust casing. Folding bead. 60 tpi. Color: Full White. 145 psi max. 700c x 23mm (23-622 ISO). 255 grams.
