I have been rolling around for the last twelve months or so using Maxxis tyre, mostly CrossMark LUST UST. I have found them to be a great tyre for racing. I have never had a flat tyre whilst using these and I put that down to their toughness, which comes without compromising speed.
I am very happy at say I am now sponsored to use these products. The whole Kona team will be rolling around on this great brand of rubber. It will be nice to have a choice of so many good tyres to cover all riding conditions.
