Schwalbe Ultremo R.1 Evolution Coloured Folding Road Tyre

Using new high tech materials and new construction principles the ULTREMO R.1 has charted previously unexplored territory.

Radial Technology - for the first time our High Density Technology makes possible to radialy, in-build a protection belt into a protection belt into a bicycle tyre. The tyre 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. The filler particles that were formally 200 nanometres in size now measure a mere 10 nanometres, or 0.00000001M.

This reduction has two crucial advantages:
1. The internal friction within the rubber is reduced, lowering rolling resistance.

2. More, smaller particles have much more surface area than few larger ones meaning the contact area is greater which results in improved grip. Result: An outstanding all-round compound that we use it in the tread centre. Beneath this lies the base compound that is light and easy rolling, while the tyre shoulders have the low legendary grippy compound.

High Density Guard - is a unique puncture protection technology only available from Schwalbe. It has been jointly developed in co-operation with American firm Warwick Mills. Warwick is a specialist maker of high density fabrics and holds 14 International patents for its weaving technology.

No other bicycle tyre protection belt is as densely woven and this technology makes it possible to make a tyre that is both light in weight and with an extraordinary high level of puncture resistance.
