...ein gemischter Haufen

Now a question, which could often only hardly be answered, exists no more:
Which wheels and which tires one uses for which area?!
With the NWB this question belongs to the past.
Advantage of the NWB:
- No rolling resistance = be faster,
- don't care about pot holes or soaked ground,
- never again check air pressure,
- never again need an air pump,
- never again flat tires!! :o)
