Schwalbe Ultremo R.1 Clincher Tire 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. Triple Nano Compound a completely revised Nano-Sized Polymer base and fillers has made Schwalbe Triple Compound even better. The filler particles that were formerly nanometers in size now measure a mere 10 nanometers, this reduction have two crucial advantages. First the internal friction within the rubber is reduced, lowering rolling resistance. Second, smaller particles have much more surface area than few larger ones meaning the contact area is greater that results in improved grip. Radial Technology for the first time, High Density Technology makes it possible to integrate a protection belt radially into a bicycle tire. The tire retains its shape better. Internal friction and rolling resistance are reduced.
