Technologies

Soft
Some of the tyres use a tread rubber with a softer durometer, so the S also stands for Softer and more Supple. Softer S treads are mainly used for track and cyclocross tyres.

Handmade
Handmade tyres combine many attributes to create the most comfortable and low rolling resistance tyres. 

Latex
Latex tyres are stronger, lighter, softer, absorb shocks and adapt to any object that hits them, reducing rolling resistance.

PPS
The puncture protection strip is a special fabric placed between the tread and the tyre carcass to increase puncture resistance.
