Don't bother, I was sadly seduced by the name more than anything and foolishly put a full set on my cross bike. At first I thought they were just poor whilst bedding in but even after a dozen rides they were no better, I even refaced them with sandpaper but in the end in just binned them! I happened to be in go outdoors and saw some cheapies which were only £7 per set so I thought what the heck I will give em a try, so far they are performing quite well and the bonus being they come with a spare set of replacement pads.
