This tire comes with options, please read below:
The Zaffiro Pro Folding, new tread for an increased safety for training. Thanks to the newly developed tread, with deeper cuts in the middle and shallower on the shoulders we achieved a better water dispersion (Aquaflow computer simulation) and a faster and safer tyre when cornering.60 TPI casing, Aramid Endura 3D Compound new compound (for a lower rolling resistance) and foldable bead all sum up to enhance the Zaffiro Pro as the ideal training tyre. 60 TPI.
The Zaffiro Wire Bead has the same tread as the Zaffiro Pro (foldable), and the Aramid Endura 3D Compound. A stronger casing combined with bead wire made from 4 twisted steel wires (for better flexibility)make Zaffiro ideal for training. 26 TPI
