Rear triangle with innovative KingPin suspension
The rear triangle is flexibly mounted on the seat tube with the help of a thru axle. The main frame also has flexible zones on the top tube and seat tube. This allows the rear triangle to flex vertically by up to 30 millimetres to absorb shocks and vibrations. This means: more control, more comfort, more traction. The carbon layup and tube diameter are adjusted for each frame size to achieve the perfect level of stiffness and flex for every type of rider. Internal cable guides protect against dirt and emphasize the tidy frame design. Numerous mounting points for accessories make the Topstone an ideal base for bikepacking adventures: the frame and fork offer space for two water bottles and two lowrider front bags. A new addition is a storage compartment in the down tube.
