Gran Turismo Composite
In designing the GTC carbon fiber frames, safety and comfort are the main factors. We use high modulus fibers for the parts which are stressed the most ? the head tube, the seat tube top and the bottom bracket area. That is why the frame still offers flex and comfort resulting from the flexible tubes. Our special production process with inner and outer molding forms ensure that the minimum of required material is used, reducing overall weight even with complex frame designs. All GTC frames have of course passed DIN -Plus testing.
Agile Ride Geometry
We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5in wheel size to the very well received portfolio. Three important details lead to the very agile character. Increased fork offsets let us achieve the same trail as our 26in bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle.
X12 Through Axle
In this system, a cone is used to form a play-free connection. It is only necessary to tighten the axle from one side. The position of the wheel is done by an insert in the right-hand dropout which is secured by a bolt. The main advantages of the Syntace system are quick and simple changing of the wheel, reliable position of the brake disc and higher stiffness of the rear of the bike. This allows the assembly to be made lighter than a conventional through-axle.
