Technologies

At CST, our goal is to provide customers with the highest quality tires. Customers can be certain that in our portfolio they will find the perfect tire to meet any requirements. CST products work very well with bikes from every segment. We offer more than 100 tread patterns in many sizes, retractable or wire beads, technologies improving the durability of tires and puncture resistance. In this section you will find the necessary information about our tire technologies to help you choose the right tire for your needs.

Anti-puncture systems

Select system

APL

It has an extra 0.7mm layer of rubber, located between the treat and the carcass. This layer protects the tire from cuts, small pieces of glass and other sharp objects that may be on the road. Tire structure and technologies.

KEV

It contains Kevlar fibers in a 1.5mm natural rubber insert, located between the tread and the carcass. This layer protects the tire from cuts, small pieces of glass and other sharp objects that may be on the road.

EPS

It has an extra rubber insert with polyamide fibers between the tread and the carcass. The super-light anti-perforation insert protects against pieces of glass, thorns, nails and other sharp objects that could puncture the tire and the inner tube.

EPSBTB

A system providing full-surface puncture resistance, developed for racing and ATB tires. It makes the tire extremely light and cyclists feel no difference.

LDP

It has a 3 mm insert between the tread and the carcass. The High Protection insert gives extra protection against inner tube punctures. Made from a special rubber compound, it features high “reflectivity”, so that if you run into sharp pieces of glass or other sharp objects, they are ejected from the tire and you can continue your ride.

HPR

It has a 5 mm insert between the tread and the carcass. The High Protection insert gives extra protection against inner tube punctures. Made from a special rubber compound, it features high “reflectivity”, so that if you run into sharp pieces of glass or other sharp objects, they are ejected from the tire and you can continue your ride.

DBR

A tire with the Double Breaker system has a double anti-puncture system. This means twice as much protection. The addition to the APL system here is a densely woven EPS layer. This ultra-modern protection reduces the risk of punctures to a minimum.

Tyre technology and construction

TPI

The density of the braid is measured in TPI (Thread Per Inch), i.e. the number of nylon threads per square inch. The higher the TPL, the more resistant the tire is to high pressure and sharp objects. A higher TPI gives the tire better ground adaptation, offers a smoother and quieter cycling, and most importantly - it makes the tire lighter. As a result, a higher TPI makes the tire “faster”.

Compound

Single – One rubber compound used for the entire tire. Optimized for tire long life and very good tire performance.

Dual - Two rubber compounds used in one tread (harder in the middle, softer on the side of the tread). Improves the grip of the tire.

Triple (3C) - three types of rubber used in a single tread are selected to reduce rolling resistance, reduce tread wear and improve traction.

Single-Ply Casing

A single layer of nylon that binds the tire together. It extends from bead to bead. The single ply adapts well to the terrain and offers good weight.

Wire Bead

The bead uses a wire to hold the tire to the rim when inflated. The wire used in the bead will not expand, but is also heavier.

Foldable Bead

The use of a foldable bead helps to reduce the weight of the tire without losing strength. Thanks to these materials, the tire can also be “folded” to a small size.

Double anti-puncture system. The addition to the APL (Anti-Puncture Layer) system here is a densely woven EPS layer. This ultra-modern protection reduces the risk of punctures to a minimum.

The technology, which uses a nylon braid with a value of as much as 170 TPI. This achieves an extremely low weight without compromising its durability. Rolling resistance is very low and the grip of the tire in difficult terrain is very good.

The tire with this system allows you to ride without classic inner tube by using specially adapted “milk” with sealing properties. The task of the milk is to cover the defects formed in the tire while cycling. It allows to reduce the weight of the whole set of wheels even by several dozen grams. Thanks to this, we can ride on lower pressure, which will cause that our adhesion to the surface will increase dramatically.
