io ho comprato le gomme da mountainbikes.net ed assieme mi è arrivato il cataloghino
maxxis.... le HR e le Ardent lust sono date con mescola MAXXPRO.... quindi mescola singola 60a...
citando il sito maxxis:
The MaxxPro 60a compound is great for varying terrains and weather conditions. Only Maxxis has exclusive use of the Exxpro polymer, created by Exxon. Our engineers have blended Exxpro with our own MaxxPro elastomer, which allows soft tires to have a long tread life without compromising the increase in traction that soft compounds provide.
All MaxxPro tires benefit from 100% perfectly dispersed carbon black.
Maxxis technology allows for the carbon black molecules to be ground smaller and thus more closely arranged than carbon black found in other manufacturers compounds. The result is a smoother tire surface that wears longer than traditional compounds. Maxxis perfect dispersion of carbon black also minimizes cut growth in instances where the tread becomes torn or cut. The tire also rolls faster as a result of the rubber recovering more slowly after shaping itself to the terrain. MaxxPro is one of the many technological advantages brought about by our more than thirty years of producing bicycle tires.
