I have been a long time user of Continental Grand Prix 4000s (with Black Chilli) tyres but have plan to switc over to trying out a set of Schwalbe Durano once my current tyres wear out. Just interested in trying out a different tyre plus they do a 20" version which I now need on the front on two of my bikes.
I have had good experiences but with the Grand Prix 4000s for sure.
