Kama Velta HT 120 — a model for urban and hybrid bicycles, where the main priorities are low rolling resistance and the ability to withstand high loads. The tire is designed for paved and rolled dirt roads in regions with a moderate climate.
Optimization
The key feature is a smooth tread in the area of the main contact patch. The absence of an aggressive pattern minimizes energy losses during rolling. This gives a real reduction in effort — you accelerate faster and maintain speed on a flat road for longer. At the same time, the smooth surface increases the actual contact area with the solid surface. And the larger the contact patch, the more evenly the load from the cyclist and luggage is distributed.
"Scale" for traction
On the edges of the tread, there are dense rows of rounded semi-circular blocks, resembling fish scales. This is not just a design, but a functional geometry. When moving in a straight line, these blocks do not touch the road, maintaining low resistance. When the bike is tilted in a turn or when driving on soft ground, the scale-like blocks successively come into contact, creating many micro-gripping edges. The rounded shape provides a smooth entry. The directed orientation of the blocks improves traction when braking and prevents lateral slipping. This design increases safety at high speeds. During sharp maneuvers or emergency braking, the tire does not lose grip.
Reliability throughout the lifespan
Here, a high-strength cord with a diagonal scheme of layer crossing is used. This provides:
- resistance to local punctures and cuts;
- resistance to deformation;
- the frame does not stretch and does not delaminate even during long storage inflated.
Key features of Kama Velta HT 120:
- smooth central tread — minimal rolling resistance, easy acceleration and speed maintenance;
- scale-like blocks in the shoulder areas — smooth entry into turns, reliable traction when tilted;
- diagonal frame made of high-strength cord — strength and puncture resistance, maintaining shape throughout the lifespan;
- chambered design — simplicity of repair in field conditions, compatibility with standard bike chambers.
