Casings and Tpi<br />
Casing construction and specifi cations<br />
for <strong>Continental</strong> tyres<br />
We mainly use nylon fabric to build up our bicycle tyre casings. This<br />
material has an extremely high tensile strength, and can withstand the<br />
effects of weather during biking, and can also be processed easily in<br />
combination with rubber. <strong>Continental</strong> uses the four quality grades<br />
22 tpi, 28 tpi, 60 tpi and 110 tpi.<br />
Tpi is the number of fabric threads per inch or per 2.54 cm.<br />
The fi ner the fabric, the more fl exible and puncture-proof the tyre will<br />
be. The coarser the fabric, the more rigid and cut-resistant the tyre.<br />
So the right choice of fabric depends on the intended application.<br />
We add anti-puncture reinforcement to the basic three-ply casing.<br />
This may be in the form of a single-ply or two-ply Nylon Breaker.<br />
It may be additionally reinforced with Kevlar or be made from<br />
rubber. In our Grand Prix 4000 and Competition high-performance<br />
tyres we now incorporate a breaker made from Vectran, a liquid<br />
crystal fi bre with ultra-high resistance to cuts and punctures.<br />
2,54 cm Tread<br />
To enable you to understand the tyre’s construction, our tyre specifi<br />
cations indicate the number of plies in the basic casing, the total<br />
number of fabric threads in the three plies of the basic casing and the<br />
type of puncture protection:<br />
110 threads per 2.54 centimeters<br />
of a single layer of fabric<br />
Puncture-proof plies<br />

Beads<br />
For instance:<br />
Grand Prix 4000:<br />
3/330 + Vectran Breaker is equivalent to:<br />
3 Fabric plies/3*110 tpi + Vectran Breaker<br />
Contact: 3/180 + SafetySystem<br />
is equivalent to:<br />
3 Fabric plies/3*60 tpi +<br />
SafetySystem Breaker<br />
Olympic: 2/220 is equivalent to:<br />
2 plies (aramid in this case) / 2*110 tpi<br />
Patented and lightweight sidewall protection<br />
Improved sidewall protection<br />
An extremely durable polyamide fabric that protects the extra-fi ne,<br />
high- performance casing from cuts, punctures and abrasion.<br />
Lightweight durability<br />
<strong>Continental</strong>’s proprietary production process applies the DuraSkin<br />
fabric to only the exposed sidewall area resulting in a mere 10 grams<br />
of added weight.<br />
All new appearance<br />
DuraSkin’s mesh layer adds a high-tech look to our entyre line<br />
of performance MTB tyres.<br />
The term ProTection indicates that a tyre has DuraSkin technology.
