From Cycling Weekly March 2016 but interesting turn around for Continental perhaps:
Graphene was first isolated in 2004, and companies began to heavily invest in its commercial applications after 2010 when Andre Geim and Konstantin Novoselov of the University of Manchester won the Nobel Prize in Physics for its creation. It is said to be 100 times stronger than the highest quality steel while remaining six times as flexible, and it conducts electricity like copper. Graphene is already widely used for electronics components such as semiconductors.
Vittoria is the only company currently manufacturing graphene tires on a large scale, and they are the ones providing the information about the graphene-enhanced rubber compound. Other major bike tire companies have experimented with graphene, but believe that other materials are better. For instance, the head of bicycle tire product development at Continental, Christian Wurmb�ck, told Cycling Weekly that a carbon powder compound called Carbon Black is superior to graphene in tire manufacturing.
In the past we did some trials with graphene in the casing and tread of our tires. However, although the directionality of the compound brought some benefits to the casing, the development of our Carbon Black compounds is at a higher level, so there was no need to jump back on graphene.
Maybe so, but graphene could have many applications in bicycle design beyond tires. Vittoria has also added graphene to the carbon fiber in its rims, and engineers are looking for ways to incorporate the material into frames. Some even speculate that graphene could be woven into textiles to make smart clothing, for cyclists and for everyone else."
