Triple Star Compound.

We have taken the development of Triple Compound a step further. In the
course of innumerable series tests, prototypes, laboratory and practical tests
we developed a system of highly specialized single compounds. We arranged
these into Compound-Teams, each engineered to fulfill a specific job. The job
description of the Ultremo ZX is „as fast as possible“ so the Compound-Team
is RaceStar Triple Compound.

High Density.

High Density Guard is a unique puncture protection technology only available
from Schwalbe. No other bicycle tire protection belt is a densely woven and
this technology makes it possible to make a tire that is both light in weight
and with an extraordinary high level of puncture resistance. The latest version
is HD Speed Guard that is focused on competition tires. It provides the same
high level of protection, but with significantly reduced rolling resistance.
