Active Comfort Technology - Embedded in the tyre construction the Active Comfort Technology absorbs vibrations and smoothens your ride.
Lazer Grip - the lazered micro profile structure expands over the tyres shoulder and provides outstanding cornering.
New BlackChili Compound - visually blacker, the new mix of BlackChili aids reduction of rolling resistance and increased grip.
Constructed from 3 plies, totalling 330Tpi.
