The concave deflection of the seat stay increases its ability to absorb minor shocks due to road roughness. Due to this property the wheels remain permanently in contact with the surface, maintain the direction better, the ride is safer, more considerate, and more comfortable for the rider. It is used on the A4400 and A5500 models.
Stiff, straight, short - are the characteristic properties of the chain stay, featuring a direct relation to its higher stiffness, thus also in the acceleration of the entire bike. We use it for the MTB Infinity and Respect and for the Cross Infinity Series models.
The characteristics of the S-shaped profile of the seat stay secure its ability to absorb minor terrain roughness. We use it on our MTB Infinity and Respect models as well as on the Cross Infinity and Respect Series.
The specific shape of the down tube utilises the twisting of the horizontal flattening of the lower section verging into vertical flattening in its top section. The BTP system enables the increase of the side stiffness of the connection of the down tube with the BB shell, thus eliminating the load in the connection with the head tube. We use it on the MTB Infinity, Respect and Logic models, as well as for the Cross Infinity and Respect Series and the FSX – full suspension mountain bikes.
Hydroformly shaped frame tubes on our road frames A4400 and A5500 are creating the replica of carbon frame model CA7707.
