Field of application: All categories

• Tubeless tyres:

Special rims (with or without spoke holes that are sealed to be airtight) and tyres are sealed to be airtight and

make a tube superﬂ uous. Nevertheless, in the case of a breakdown such a tyre can be mounted.

Field of application: Mountainbikes, crossbikes, racing bike/street

• Tube tyres:

The tube is sewn into the tyre. The tyre, including the tube, is adhered during assembly on to the specially

built rim. Here the assembly instructions of the tyre, adhesive and rim manufacturers are to be followed.
