I just got my hands on some green koxx bloxx, I went for a ride and they were sh*t . I decided to carry on with my ride thinking they had to be worn in, but there still crap. I did just what tarty bikes said, with the light grind. But they don't work. I then got them a bit wet because it says they worked well in it. They were even sh*ter. any one got any ideas. I think I will send them back josh
