Scwalbe Ultremo R 700x23 Folding Tyre

Created using new construction principles and with new high tech materials. Rolling
resistance and weight have been radically reduced!
Radial Technology. For the first time, our High Density Technology makes it possible
to integrate a protection belt radialy into a bicycle tire. The tire retains its shape
better. Internal friction and rolling resistance are reduced.
Triple Nano Compound. A completely revised nano-sized polymer base and fillers has made
our triple compound even better. Small particles - less internal friction.
Ceramic. The addition of a ceramic coating is entirely new. Small pieces of glass that
remain embedded in the tire and slowly cut their way through a protection belt are now
stopped by the tough, ceramic particles that blunt the edges of the glass preventing its
destructive migration.

Improve your personal best by a factor of R.
