Schwalbe Ultremo R.1 Tire - 700 x 23C Folding Bead

Ultremo R.1 - Created using new construction principles and with new high tech materials. Rolling resistance and weight have been radically reduced!

A particularly flexible fabric coating has reduced rolling resistance by a further 10% compared to the 2009 Ultremo R.

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.

Improve your personal best by a factor of R.
